There can be no question that the practice of vivisection hardens the sensibility of the operator and begets indifference to the infliction of pain, … - Henry Jacob Bigelow

The horrors of have supplanted the solemnity, the thrilling fascination, of the old unetherized operation upon the human sufferer. Their recorded phenomena, stored away by the physiological inquisitor on dusty shelves, are mostly of as little present use to man as the knowledge of a new comet or of a tungstate of zirconium: perhaps to be confuted the next year, perhaps to remain as fixed truth of immediate value, — contemptibly small compared with the price paid for it in agony and torture.

Every discoverer of a new truth, or inventor of the method which evolves it, makes a dozen, perhaps fifty, useless combinations, experiments, or trials for one successful one. In the realm of electricity or of mechanics there is no objection to this. But when such rejected failures involve a torture of animals, sometimes fearful in its character, there is a distinct objection to it.

Watch the students at a vivisection. It is the blood and suffering, not the science, that rivet their breathless attention. If hospital service makes young students less tender of suffering, vivisection deadens their humanity, and begets indifference to it.
