I thought the experiment ought to be repeated, and accordingly the next morning I made another trial. The patient this time was a working shoemaker, thirty-eight years of age, exactly in the same far-gone, hopeless state as the patient of the day before. In his case, the inward commotion caused by the injection was more powerful; twenty minutes after the injection he was able to see, to understand, to speak, to raise his head; but this vital recovery was, as in the former case, but of short continuance, and two hours and a half after the operation the man expired.

After these experiments I dissected the two bodies, and then, finding that their lungs were infiltrated with water, I understood that the alkaline solution had not been assimilated, that it had stopped in its passage into the pulmonary parenchyma, to the detriment of the functions of the hæmatosis. I also understood that the proper injection, instead of distilled alkaline water, would have been the serum of the blood, drawn at the very moment from some man or animal.

The conclusion which I drew from these experiments was that a variety of operations, made at different stages of the malady, might lead to beneficial results, especially if we succeeded in transmitting the cholera to animals, as that would enable us to test a large number of curative agents and to pursue a methodical course of experimentalization.

From all I have said, I infer that life, health, and disease, being subject to the same laws throughout the whole animal kind, it is certain that the physician should possess precise knowledge as to the organization, the functions, and diseases of animals. That by proceeding in this manner, we shall advance from the simple to the complex, from the plant to the animal, and from the animal to man. That we must of necessity emerge from the state in which we are now entangled by founding and establishing in London a College of the Natural and Medical Sciences. Every medical pupil might spend two years in this college, receiving in it an experimental and practical training; he would devote himself in it to the chemical analysis of all bodies, to physiological experiments and tests, without limit and of every kind.

Most deeply do I appreciate the many difficulties and obstacles that would interfere with the execution of such a design. In our civilized age, nations seem rather bent on seeking out the means of exterminating each other than of protecting themselves and animals from epidemics and epizootias. It is believed that every first-rate kingdom now spends from 400 to 500 millions of francs (16 to 20,000,000l.) annually in maintaining their land and sea forces, whilst one-half of their populations are living in misery and ignorance, in disease and corruption. The time is not come – shall we ever see it? – to employ the vital powers of the peoples, to better incessantly their social condition. Perhaps, by reason of its organization, the Government of this country would not be authorized to devote 100,000l. or 200,000l. to the establishment of an institution like the medical college I suggest, notwithstanding its paramount necessity. But England is in the habit of doing great things independently of the Government. In default of the ruling powers, then, let me appeal to the national initiative, for if the spectacle which we are at present witnessing was not, in the case of England, one of those trials which invigorate a people by the salutary teachings which they bring; if it did not induce them to take some energetic resolution by which their interests would be saved and their power enlarged, it would indeed be a deplorable sign of the times and make us despair of its future.

Moreover, to show the urgency of founding a College of Natural and Medical Science, let us add, that in every other country they are endeavouring to unite this indispensable complement to medical education. The German universities, the Faculty of Paris, have, for several years past, incorporated a course of comparative pathology, with the other series of public lectures.

It is not a mere Utopia that we propose, but an extension and improvement, all the parts of which are already prepared. If this College could be thrown open to-morrow, competent professors would be ready at the call of duty to indite the programme for this instruction within twenty-four hours; and as for the professors themselves, there would be enough to choose among the large body of efficient scholars who do honour to the country.

If we have been rightly understood, we desire to see established in London an institution which would afford an equivalent to what exists in Paris, at the Museum and Collège de France, where numerous courses of lectures on anatomy, physiology, physics, and chemistry are given. Only in London this special college would be formed and organized on such a scale as to bear away the palm from every previous foundation of the same kind; it would be an institution unexampled in the world, out of whose halls would one day come anatomists, physiologists, and pathologists of the very highest order of excellence. – But organic matter would not be the sole object of this instruction, for the animal is something more than matter. Courses of medical history and philosophy, of really general pathology, would introduce the students to the grand phenomena of nature, to the great laws which govern the worlds and the globe; and descending from the heights of science to the observation of the infinitely minute, they would never forget the important part of the vital powers, and of that unknown power called at different times by the names of πνευμα, archéc – mind and soul.

The Regent's Park would, we think, be the proper site for this college, as the contiguity of the Zoological Gardens would afford continual opportunities for investigating the diseases of animals.

Moreover, this college would not trench upon or interfere in any manner with those medical and veterinary establishments which at present exist; it would ally itself with, and complete them, nothing more. The instruction received at this "College of Natural and Medical Science" would be so useful and necessary, and so attractive withal, that the sons of the great families would come to it to finish their collegiate studies, to the great benefit of the country. Other young men, in considerable numbers, would flock to it from various parts of the world. The foundation of such an institution would be an epoch in the history of science, and would give England another claim to the esteem of nations.

I conclude, then, with a conviction that a nation which owes to Lord Bacon, the founder of experimental philosophy, his imperishable book on the restoration, the method and teaching of the sciences; to Harvey, the circulation; to Priestley, the constitution of chemistry; to Sydenham, the modern Hippocrates, his treatise on "Practical Medicine"; to Jenner, vaccination; and to Charles Bell, the discovery of the sensitive and motor nerves – is a people too great and too enlightened to retrograde; and that, if the epizootic of ox typhus did find them at first unready and disarmed, they will in the end convert this disaster into a new source of greatness and strength.

Such is the sincere hope which I cherish and the prayer I offer up for the happiness of a country which, for the future, has become my own.

APPENDIX

Note ABremen, August 30.

The following report, drawn up by two German veterinary surgeons, of a recent visit to London to examine into the cattle murrain, has been furnished by the agent of the North German Lloyd's at Nordenhamm: —

"On Wednesday, the 9th instant, we, the undersigned, were requested to be at Nordenhamm, if possible, the following morning. Upon our arrival we were asked by the agent of the North German Lloyd's, who had consulted with several of the chief cattle exporters, to undertake a voyage to London at once in the steamer Schwan, in the interest of the cattle export from the Weser. The object of our mission was, first, to examine as closely as possible into the epidemic cattle disease raging in and around London for some time past; then carefully to observe the treatment of cattle upon the vessel during the voyage, upon arrival, and at the time of disembarkation; lastly, to use every means in our power to prevent obstacles being opposed to the continued export of cattle from these ports to England.

"Furnished by the agent of the North German Lloyd's with letters of introduction to cattle dealers in London, and with the necessary funds, we left Nordenhamm in the steamer Schwan, Captain Christensen, at 4 P.M., on the 10th instant. The vessel carried 347 head of large cattle, 2 calves, and 260 sheep. Favoured by very fine weather, we arrived in the Thames at 2 P.M., on the 12th. At the beginning of the voyage the animals were rather uneasy, trampled a good deal, and caused considerable motion in the ship; after a time, however, they became quiet. A sharp, penetrating smell was easily perceptible in the 'tween decks of the ship, which was quickly removed upon a light breeze springing up, by means of the excellent ventilation and numerous air-pipes and wind shafts. The animals were several times watered, and it was easy to see how greatly they were refreshed. The hay in the racks, on the other hand, was hardly touched.

"Upon arriving in the port we were introduced by the captain to the two veterinary surgeons stationed here to inspect the cattle, and witnessed the rapid disembarkation of the cargo, all of which were thoroughly healthy, not one being condemned. The cattle, when landed, were immediately brought to carts standing in readiness and transported to London, where they are cleansed and then driven into the adjacent fields.

"After doing all in our power to attain the object of our journey, we went back to the port to wait for the Schwan, having first thoroughly cleansed the clothes we had worn during our inspection of the diseased cattle. The Schwan came in shortly after our arrival, and disembarked 256 head of large cattle, 12 calves and 400 sheep, all in good condition. Mr. Philipps, the London agent of the North German Lloyd's, was on the spot, together with several reporters from newspapers, who wished to see by personal investigation how and in what condition cattle are brought from the Weser.

"We re-embarked on the Schwan upon the 19th. The crew were engaged during the voyage in carefully cleansing the ship. The weather was fine, and we arrived safely at Nordenhamm upon the 21st.

Professor Simonds having had such opportunities of investigating those diseases as they existed in England and in foreign countries as were possessed only by a few Englishmen, might be permitted to offer a few observations. He had been appointed by the Royal Agricultural Societies of England and Ireland to proceed to the Continent in 1857, when there was a rumour that the disease which existed among cattle in this country at the present time was prevailing in Mecklenburg. Consuls sent despatches that the rinderpest was prevailing largely, and the Government, as a precautionary measure, closed the ports against the introduction of cattle from the Baltic to this country. He found, however, from his observations abroad that since 1817 there had been no disease of this kind westward of a line between Revel in the Baltic and the Gulf of Venice, but to the eastward of that line it had existed. He came up with the affection at the Carpathian mountains, where it was raging in 1857 just as it is raging in England at the present time. Not only had it existed there, but it had been carried into the interior of Russia in the ordinary method of the cattle trade. A person who was in the habit of purchasing cattle attended a fair and bought a number of animals, and took them to his own farm, and in the course of ten days one or two were seized with the disease, and the result was there was a gradual spread of the evil in that district. It gained ground until the Government instituted the sanitary police regulations, which, though they were such as would be considered strange in England, were, he believed, absolutely necessary for the extirpation of the plague. It was undoubtedly true that no foreign animals had been seized at our ports or in the metropolitan market; but it was not necessary for the case they had in hand to say whether the disease was or was not of foreign importation. There was this fact before them, that it was not until the month of June that the disease appeared in England. A certain number of animals came out of a diseased district. He had documentary evidence that animals came from Revel and came from the district of Esthonia. He had before him proof that the disease now in England was raging in that district. They had proof that shortly after the arrival of those cattle in England the disease manifested itself here. He admitted there were difficulties in the way of checking the importation of foreign cattle. The Government had its eyes open to the matter, and he did not think it possible for the Government to have done more than they had done or to have done more quickly what they had been doing. At this moment half the supply of the metropolitan market came from foreign countries, and he did not wish to convey any reflection by saying that this disease had its origin from abroad. He would admit that the animals from Germany and Hungary were coming in a healthy condition; but he could not admit that they came from Russia, Poland, or Galicia in so perfect a condition, because the regulations there were not sufficient to stamp out the disease. The Government had made an inquiry as to the general health of cattle on the Continent. They believed France, Belgium, Holland, Schleswig-Holstein, Oldenburg, and a large part of the Continent that supplied cattle to this country were free from disease. This went to show that we had admitted a disease not from where we received our supplies of meat, but from some other district. Then it must be associated with the fact that it came into this country when animals arrived here from an infected district in Russia. Animals from Germany and Hungary were often shipped and mixed with others from a diseased district. As regarded the disease being spontaneous, we had been free from it for twenty years. What was the state of our cowsheds fifty years ago? Were they not in a more filthy condition than they are now? If, therefore, the disease had been induced from common causes it would have been here years and years ago. It was no reflection to say that a great many cases could be traced directly to the metropolitan market. Take one case which occurred in Sussex. Certain cattle had been bought in the metropolitan market and were taken home. In three or four days they were ill, and presented symptoms of this affection. In a few days more the cows and calves were dead. In another instance calves were bought in Chichester Market, where they had been taken from London. The result was the death of twelve cows and ten calves. The people had other cattle on the same farm, and not one of them took it. He could say, too, that persons who had only one animal had lost it by the disease. How had the disease got into Norfolk and Kent but by the animals which went from the metropolitan market? He could prove by documentary evidence that it was so. He could show there was not a single instance where the origin of the disease could not be traced to the metropolis. It was the most fearful visitation that had ever been seen in England. They had adopted a system of compensation in Norfolk, and if by this meeting something was done to shut out the animals of infected districts, no doubt the promoters would receive not only the thanks of London, but the country generally.

Mr. Gibbins – Now, if the disease came from abroad, and diseased cattle were shipped on the other side of the sea, no doubt the voyage would concentrate and aggravate the disease. The Government inspectors reported, however, that not one instance had been seen of foreign cattle so diseased, nor had any been seized and destroyed in London or anywhere else. Whether the disease came from abroad or elsewhere he was not able to state. Sir George Grey asked him whether he had found any disease among the foreign cattle that came into the market. He said not one. They had, no doubt, many instances of the disease amongst the cows that were ordinarily called milch cows, but that were not milch cows when they came to market, because one effect of the disease was to deprive the animal of milk. These were then sent to the market and sold as fat stock. He could only say they had had no cases, except in cows, whether they came from the dairies in London or elsewhere.

M. Dembinski, Professor of Analytical Chemistry and Natural Science, had also addressed a communication to the Lord Mayor on the subject. The prevalent Rinderpest, he said, originated in the steppes of Podolia, from which considerable herds of cattle were exported through the steppes to Moscow, St. Petersburg, Riga, and Revel, and thence to the ports of Memel, Königsberg, Dantzic, Hamburg, Kiel, and the Hague. Deprived of congenial food and pure water on their transport through the steppes, and then arriving at marshy lands, the exhausted animals drank the stagnant water, which, during hot weather, exhaled a pestiferous malaria, and infected them with a predisposition to the epidemic in question, which developed itself into a kind of fever on the voyage to England in a crowded condition.

Note DInternational Veterinary Congress, Vienna,August, 1865.

With regard to the cattle plague, it may be well to state that Austria has been most unfortunately situated, from the readiness with which Russian cattle have been admitted into the country at various parts of the western and southern frontiers. At the opening of the Congress this difficulty was particularly noted by the Ministerial counsellor, Dr. Vell, who attended on behalf of the Government, for the purpose of welcoming the assembly, and giving an assurance that its deliberations would meet with all the attention they deserved. He specially referred to the fact that the laws relating to cattle disease prevention had been entirely revised in 1850, but that the Steppe murrain continued to be introduced by smuggled stock into the western and southern provinces of the State. It was therefore necessary to attempt a more effectual control over the propagation of so disastrous a malady.

Herr Pabst welcomed the meeting on behalf of the Minister of Trade. He said that the value of the cattle of the Austrian dominions considerably exceeded one hundred million pounds sterling (one thousand million Austrian florins), and that cattle plagues completely put a stop to the development of that essential branch of agriculture which embraces the improvement and increase of live stock in a country. He assured the assembly that all would be done that was possible to improve the existing state of matters, and that he hoped they would greatly aid the Government by the discussions which would take place and the conclusions at which they would arrive.

I may state, by the way, that an opinion rather generally expressed by some, and stoutly maintained by others, was that the peculiar disposition of some of the Austrian subjects, and the feeling existing in Hungary against State measures, rendered the law, to a great extent, inoperative. I can, from personal experience, state that although stringent and most efficient means are used for the suppression of cattle plagues, and with the best results in Austria proper, there is great difficulty in carrying out the law in districts where Austrian rule is at a discount. Indeed this is clearly indicated by the manner in which the Rinderpest penetrates into Austria, where the laws are similar to those in the kingdom of Prussia, which is, and has long been, completely protected from invasions of the disorder.

At the meeting of the first International Congress, held in Hamburg in 1865, Dr. Röll stated that owing to the length of time to which the quarantine for Russian cattle extended on the Austrian frontier, herds of cattle were often smuggled through, and companies had been formed for the purpose of insurance against seizure by the authorities. The unlawful traffic was therefore carried on with comparative safety to the dealers, who cared not what misfortune they brought on a country if only their personal ends could be served. This question was the first to occupy the attention of the Congress last week; when a resolution was proposed to shorten the period of quarantine for cattle from Russia into any country from twenty-one days to ten. The discussion was keen. It was stipulated, however, that the quarantine should be carried out most strictly over all parts of the frontier, without respect to any breed of cattle or other circumstances which might be brought forward as exceptional reasons for retaining animals in quarantine. The committee appointed to prepare a succinct report on the subject included Professors Unterberger, Seifmann, Werner, Zlamal, Hertwig, Haubner, and Röll; and the committee decided in favour of the shortened quarantine, on the following conditions: – First – When the establishment of quarantine institutions is effected in accordance with the requirements of trade and the peculiarities of the frontier, special attention must be paid to the erection of quarantine stables, &c., where there are facilities for procuring an abundance of fodder and water. Second – The animals to be kept under efficient veterinary supervision wherever they have to submit to quarantine. The inspectors must be properly qualified veterinary surgeons. Third – The use of a brand to indicate that the animals have been in quarantine. Fourth – The effectual disinfection, by washing and otherwise, of animals as they leave the quarantine. Fifth – The introduction of a poll-tax along the eastern frontiers, and the appointment of proper veterinarians to be on the watch as to the health of cattle along the frontiers. Sixth – Careful supervision to be placed over the traffic in cattle wherever it takes place in a country. Seventh – The punishment to the full extent that the law allows of all who break the rules relating to quarantine or other means for the prevention of the cattle plague.

Professor Hertwig, of Berlin, whose opinion is always listened to with great respect in veterinary circles, stated his reasons for adopting these resolutions now, whereas in 1863 he was against shortening the period of quarantine. He referred chiefly to the importance of not offering temptations for cattle dealers to evade the law by insisting on unreasonable restrictions. The feeling of the assembly was greatly in favour of avoiding vexatious and expensive measures, which might greatly interfere with the employment of capital in cattle traffic. A small number of professors, not exceeding eight or nine, held out for a quarantine of twenty-one days.

It may be as well to state that quarantine regulations, which have been regarded as almost useless in the prevention of human disorders, from the great difficulties in the way of carrying them out efficiently, are recognised as of great value in controlling the propagation of cattle plagues. It is possible to control the movement of herds, and the governments of Central Europe have found it absolutely essential so to do. Indeed, the ablest medical men who have written against the adoption of a quarantine system for human small-pox and cholera, such as Professor Siegmund, of Berlin, acknowledge its value and absolute requirement with regard to the Rinderpest. A professor from Galicia argued in favour of controlling the movements of people wherever the disease appeared, and no fact seems to have been better ascertained than that of the communication of the Rinderpest from herd to herd by human beings. Professor Jessen, of Dorpat, states that in Russia the malady was at one time speedily propagated by the people, who regarded the destruction of their stock as a visitation of Providence, and who summoned a priest into their stables to pray with them that the plague might be stayed. Moving from farm to farm, the malady was by this means rapidly transmitted. In Hungary, many outbreaks result from people dressing the carcases and hawking about the meat, which, even where human beings remain uninjured, is deadly to the cattle whenever the water with which it is washed is thrown about the yards, or the meat is hung up near sheds containing living animals.
