Note 204 — GENERAL REMARKS ON THE MEDICAL EVIDENCE REQUIRED TO SUBSTANTIATE AN ACCUSATION OF POISONING.

The author refers the reader to the first volume of his Pharmacologia, page 124, note. In addition to what he has there observed it may be stated, that many fallacies have arisen in pharmacology, from deducing conclusions respecting the effects of remedies upon inferior animals. One example will suffice.—Several substances have gained the reputation of Styptics, from the effects which have followed their application to the wounded and bleeding vessels in the extremities of the horse and ass; whereas the fact is that the blood-vessels of these animals possess a power of contraction which does not exist in those of man, and to which the cessation of the hemorrhage, fallaciously attributed to the styptic, is to be wholly attributed.
