"There is no question that vivisection is, in many cases, inseparable from suffering and that suffering is inevitable to the pursuit of the practice; further, that the suffering which is caused is altogether a minor matter to some of the men who cause it. This the public has yet to realize. It has to understand that in assenting to and encouraging experiments on living animals it is giving its consent to possibilities of illimitable suffering."
