Michael Foster, Popular Science Monthly (1874)
“ The physiology of the future, if not hampered by any ignorant restraint, will, out of the death of animals, continue to press further and further into the mystery of—and year by year bring the physician, and not the physician only, but every one, power to prolong, to strengthen, and to purify—the life of man. By no other way can man hope to gain this end. He is thereby justified for the death he causes and the pain he gives. ”
