The Bill, though introduced in Parliament, was not pressed. Another and more stringent measure for the regulation of vivisection had been introduced a few days earlier through the efforts of Miss Frances Power Cobbe and the Earl of Shaftesbury. In the conflict of opposing statements and opinions, the Government wisely concluded that more light on the subject was necessary, and a Royal Commission was appointed to investigate and report. But if the Continental party was to conquer in England, its members undoubtedly felt that it must be through audacity quite as much by silence and secrecy. At the annual meeting of the British Medical Association, therefore, Professor William Rutherford delivered an address, wherein for the second time an English physiologist openly advocated the vivisection of animals as a method of teaching well- known facts. Commenting upon this address, the editor of the Lancet remarks: "We confess that we think Dr. Rutherford presses his principle too far when he argues that, teaching by demonstration being the most successful method, we are thereby always warranted in having recourse to it. Physiology and chemistry are both experimental sciences. The chemical lecturer can have no hesitation in employing any number of experiments, or repeating them indefinitely to illustrate every step he takes; but we may fairly assume that the physiologist would be restrained by the thought that the materials with which he has to deal are not so much inert, lifeless matter, but sentient, living things. We hold, therefore, that it would be both unnecessary and cruel to demonstrate every physiological truth by experiment, or to repeat indefinitely the same experiment, simply because by such demonstrations the lecturer could make his teaching more definite, precise, and valuable."[1] [1] The London Lancet, (Editorial) August 21, 1875. Again, somewhat later the same journal brings into prominence one of the greatest difficulties attending all discussion of vivisection--the lack of agreement upon the meaning of words: "It is extremely difficult to get at the exact meaning of the terms used. The physiologist would be ready to declare his utter abhorrence of all `cruelty,' BUT THEN HE WOULD HAVE HIS OWN DEFINITION OF THE WORD. We hope Sir William Thompson was not justified in stating that revolting cruelties are sometimes practised in this country, in the name of vivisection, although we may concur with him in reprehending the performance of experiments on animals in illustration of truths already ascertained.... When the Cardinal (Manning) laid it down as the expression of a great moral obligation that we had no right to inflict NEEDLESS pain, he begged the whole question. By all means lay down and enforce any restriction that will prevent the infliction of NEEDLESS pain."[1] [1] The London Lancet (Editorial), March 25, 1876.
