In seeking to benefit mankind by vivisections, it would be necessary to have recourse to pathological facts founded on experiments on _human_ beings.”--_Longet, quoted in Fleming’s Essay_, p. 42. =Lovèn, Christian.= M.D., Prof. Med.

When a powerful unnarcotised animal was submitted to the experiment, I observed that in most cases, the arteria auricularis became smaller at the commencement of the stimulation. This occurred more surely and quickly as the animal expressed its sufferings more violently by cries and struggles. This narrowing of the artery lasted for different, but always very short periods of time, and then gave place to an enlargement even during continued stimulation.… This is, however, not always the case when a great number of experiments are made.… Once it happened that in an unnarcotised animal, immediately at the commencement of the stimulation without any signs of narrowing a very powerful distention occurred. This result appeared in the same animal as long as the sensitiveness of the nerves remained sufficient to allow the experiment to be continued.”--_Erweiterung von Arterien durch Nervenerregung, Ludwig’s Arbeiten_, 1866, pp. 9-10. =Luchsinger, B.= Prof. Physiology Vet.
