The Pros and Cons of Vivisection.
by Charles Richet.
PREFACE
To scientific readers, Professor Charles Richet needs no introduction, but to the public at large it may be necessary to mention that he is one of the best known of French physiologists. He has occupied for a good many years the Chair of Physiology in the Faculty of Medicine in Paris, and he has contributed greatly to the progress of the science to which he has devoted his life; some of his discoveries are alluded to with all modesty in the pages which follow. He is, moreover, a man of great erudition, and has been wisely selected to be the editor of a monumental work, _Le dictionnaire de physiologie_, which is issuing from the press to-day.
Professor Richet has given particular attention to the study of the psychological side of physiology, and his views on pain will be read as coming from one who is specially fitted to deal with this and other mental phenomena.
I therefore consider it a great honour that Professor Richet should have asked me to write a preface to his most interesting and convincing book on the Pros and Cons of Vivisection, and it is a great pleasure to me to commend its thoughtful perusal to all who are interested in the subject.
Professor Richet is not only one who speaks with authority, but he is one of the gentlest and kindliest of men. The science which he teaches is the science of life. To understand the meaning of vital processes it is necessary to study the living organism, and to obtain this knowledge it is sometimes necessary to perform experiments on living animals. When he defends a practice which many regard as cruel, detestable, and immoral, mainly because of the unscrupulous misrepresentations put forward by the professional Anti-vivisectionists, he does so because he is convinced that none of the epithets just mentioned correctly describe the experiments which are carried out in physiological laboratories at the present time.
These experiments are undertaken only by properly qualified persons having a due sense of their responsibilities. Every regard is paid to the comfort of the animals employed; and the ultimate aim of this work is the progress of knowledge, and the consequent relief to suffering which is so often only the result of ignorance. The benefits which accrue are felt not only by human beings, but also (as in veterinary practice) by the animals themselves. No attempt is made here to defend experiments which have not these objects in view, or which (as has happened in the past) pay no consideration to the pain an animal experiences.
I feel quite sure that if the British public were convinced that the experiments in our laboratories were all conducted in accordance with our present law, the Anti-vivisection crusade would flicker out. It is the object of those who are active propagandists on the other side to keep their agitation going, by omitting to mention the painlessness of the operations performed, or by suggesting (either directly or by innuendo) that anaesthesia is a sham. My own experience, which is a wide one, has been that physiologists not only obey the law literally, but are most punctilious in its due observance. A certain number of trivial irregularities have been reported to the Home Office by the inspectors appointed under the Vivisection Act, but there has been no case of omitting the use of anaesthetics. The majority of these offences have been for using anaesthetics unnecessarily. A certificate in certain cases is granted for the omission of an anaesthetic: this is given when the operation is a trifling one, and has never been granted for any operation more serious than the p.r.i.c.k of a hypodermic needle. Nevertheless, the operator has sometimes employed an anaesthetic even for this, and has in consequence been reported to the Home Office for infringing the terms of his certificate.
Pawloff has truly said that the ideal experiment is one performed without anaesthesia and without pain. In many cases this ideal can be realised, but in other cases it is unattainable. Physiologists have, therefore, had to select which of the two disturbing factors shall be absent, and they have unhesitatingly chosen the latter. Pain must be absent (1) on grounds of humanity, (2) because it is a far greater disturber of the normal functions than anaesthesia is, and (3) because the struggles of an animal in pain will nullify the accuracy of the experiment, and endanger the safety of the delicate apparatus which it may be necessary to employ.
Exactly the same arguments apply to the employment of the antiseptic or aseptic methods of surgery, in experiments in which the animal is kept alive after an operation to study its effects. The healing process is then painless, and there is absence of those febrile and inflammatory conditions which would otherwise complicate the issue.
It is therefore for two reasons that an experimenter uses both anaesthetics and antiseptics, (1) to save the animal suffering, and (2) to ensure the success of the experiment.
The barbarities which are recorded by Anti-vivisectionist agitators do not exist; the repet.i.tion of their stories in spite of repeated contradictions is partly due to wilful misrepresentation and exaggeration, and partly the result of ignorance of the meaning of the technical terms employed by physiological writers.
At the Royal Commission which is now considering the question of Vivisection, the cases of alleged cruelty have been one by one sifted to the bottom, and in no single case has a charge of cruelty been sustained.
Any one who cares to wade through the four bluebooks of evidence which have been printed will discover for himself that this is so. In fact, one prominent Anti-vivisection journal (the _Verulam Review_, April-June 1907, p. 186), in reference to the evidence given by one of the witnesses before the Commission, had to confess, ”Almost every one of Mrs Cook's horrifying cases seems, when examined, to melt away.”
An Anti-vivisectionist publication which has obtained some notoriety (”The Shambles of Science”) figured in a recent lawsuit. When the particular charge which was the subject of the action was investigated by a prolonged inquiry before the Lord Chief-Justice, a British jury showed their sense of the enormity of the slander by awarding the physiologist impugned the very substantial damages of 2000. An undertaking was subsequently given by the publisher of this ”hysterical work” (to quote the words of the Lord Chief-Justice) that it should be withdrawn from publication. Yet the book has been since re-issued by the authors, with the chapter that formed the subject of the trial omitted, but otherwise with very little alteration.
The libellous statements scattered through its other chapters can still be read by the lovers of sensation, and the authors doubtless hope that their readers will never take the trouble to read also the evidence before the Royal Commission in which all the allegations of cruelty have been shown to be groundless.
The subject of curare, another bugbear of the Anti-vivisection lecturer, is so adequately dealt with by Professor Richet that I will spare the reader any further discussion on that question here. I have taken the liberty of adding, in a footnote on p. 36, a statement in respect to the usages of English physiologists in relation to that drug.
The experiments of the pharmacologist in the investigation of the action of drugs can be and are carried out under anaesthesia in the same way as those of the physiologist. But the experiments of the pathologist, which consist in conveying germs and other disease products to animals, come under a different heading. One does not deny that if the animal takes the disease, suffering is produced. This is fully admitted by Professor Richet, and I think that any common-sense reader will be convinced by the arguments put forward that the practice is fully justifiable. It is difficult, as Professor Richet points out, to gauge the amount of pain an animal such as a rat, guinea-pig, or rabbit (the animals usually employed for the purpose) really feels when given a disease experimentally, and whether this is greater or less than the suffering it will endure when another disease or a violent death carries it off in the usual course of nature. It is, however, undeniable that the suffering of these animals is much less than those of human beings. A man, when he is ill, suffers a certain amount of discomfort and physical bodily pain; but this is a drop in the ocean compared to the mental worry and anxiety he endures--all that, at any rate, is absent from the suffering rabbit. The pathologist sees beyond the pain which he inflicts to the pain which he prevents. The death of a few lower animals may be, and has in the past been the means of preventing pain and disease both to the animals themselves and to human beings also, who may be counted by thousands or even millions.
If there is one piece of evidence more than another which was given before the Royal Commission that deserves rescue from the oblivion of a bluebook, it is that given by Lord Justice Fletcher Moulton. His is one of the keenest legal intellects of modern times, and he at any rate cannot be accused of having any axe of his own to grind. I regret that exigencies of s.p.a.ce prevent me from making more than one or two references to it.
He begins by taking the case of a s.h.i.+p infected with plague, and infested also with rats, the carriers of plague. The s.h.i.+p enters port. Would it be preferable to kill the rats, and so prevent them and the disease from entering the port and causing untold disaster there, or staying one's hand because the slaughter of the rats would be a painful proceeding? The captain who gives orders for the destruction of the rats inflicts pain and death on them in order to prevent greater pain and more widespread death elsewhere. The captain who says, ”Spare the rats,” is guilty of the criminal act of causing the death of many innocent human beings. So it is with the Anti-vivisectionists: they see only the pain inflicted, and do not heed the pain prevented. On this score they are in a sense logical when they call Lord Lister a brute, although he of all men living at the present time has been the means of preventing the greatest amount of suffering.
They see only the pain which he deliberately inflicted on a few rats and rabbits; they cannot see, or refuse to see the measureless amount of misery he has prevented.
In another place the Lord Justice points out that the pain inflicted in all the laboratories of the country put together during a year is infinitesimal compared to that which is inflicted every day in the slaughter of animals for food; to that which ignorant farm labourers inflict without anaesthetics, in spaying animals by thousands in order that beef and mutton may be tenderer or have a more pleasant flavour to the consumer; to that inflicted by sportsmen when their victims, imperfectly shot, die a lingering death; to that which women thoughtlessly allow in order that they may have ospreys in their hats and furs upon their backs.
So far as the satisfaction of appet.i.te, the pandering to the so-called sportsman's instincts, or the gratification of vanity are concerned, these things may go on. The average Anti-vivisectionist disregards them, or at least makes no effort to prevent them. The only kind of pain which stirs his feelings, and meets with his opprobrium, and enables him to indulge in his favourite epithets, is _the one justifiable bit of pain in the whole world_--a pain inflicted with the n.o.blest of all objects, and by the most humane of all men (for so the medical profession admittedly is), the object, namely, of preventing future pain, which otherwise would encompa.s.s the world of life.
Professor Richet has wisely not made his book too long. He has been content to select a few typical and striking examples of the benefits which experimentation on animals has conferred upon humanity, instead of attempting even to enumerate them all. He might for instance have dwelt upon the extinction of rinderpest in South Africa: here, at the expense of a few experimental animals, Koch has prevented a scourge which formerly exterminated hundreds of thousands of cattle annually, and might still be exercising this fell influence on to all eternity if the opponents of scientific knowledge had their way. He might have taken the case of snake bite, and the discovery made by his great fellow-countryman Calmette of the means of combating this deadly poison, which has. .h.i.therto killed our Indian fellow-subjects by its tens of thousands a year.
On coming to one of the most recent of beneficent discoveries, he might have dwelt upon the case of Mediterranean fever, and the way which it has been practically stamped out at Malta and Gibraltar, because the method of its spread has been discovered and the disease prevented at the expense of a few goats and other animals.
