was told that he could not move his upper jaw); but science has
to consider only the truth of the hypothesis, and not whether
conceited people will like it or not. In vain do the sentimental
champions of vivisection declare themselves the most humane of
men, inflicting suffering only to relieve it, scrupulous in the
use of anesthetics, and void of all passion except the passion of
pity for a disease-ridden world. The really scientific
investigator answers that the question cannot be settled by
hysterical protestations, and that if the vivisectionist rejects
deductive reasoning, he had better clear his character by his own
favorite method of experiment.

SUGGESTED LABORATORY TESTS OF THE VIVISECTOR'S EMOTIONS

Take the hackneyed case of the Italian who tortured mice,
ostensibly to find out about the effects of pain rather less than
the nearest dentist could have told him, and who boasted of the
ecstatic sensations (he actually used the word love) with which
he carried out his experiments. Or the gentleman who starved
sixty dogs to death to establish the fact that a dog deprived of
food gets progressively lighter and weaker, becoming remarkably
emaciated, and finally dying: an undoubted truth, but
ascertainable without laboratory experiments by a simple enquiry
addressed to the nearest policeman, or, failing him, to any sane
person in Europe. The Italian is diagnosed as a cruel voluptuary:
the dog-starver is passed over as such a hopeless fool that it is
impossible to take any interest in him. Why not test the
diagnosis scientifically? Why not perform a careful series of
experiments on persons under the influence of voluptuous ecstasy,
so as to ascertain its physiological symptoms? Then perform a
