![find this author confounding ‘together coagulation, consolidation under atmospherical temperature [or. jellying] and congelation [or freezing], which is the more remarkable, because the freezing of blood was among the experiments he must have read a few minutes before, as contrasted with coagulation. It is equally surprising, too, that he should have overlooked Mr. Hunter’s proof that the blood does coagulate [not indeed congeal] within» the body, and even within the vessels, without any aneurism. It is true, it coagulates when out of the body, but there is reason to believe not when it is . dead; for if an animal is killed so instantaneously that no contrac- tion of the muscles follows, that is, that the body never stiffens, the blood likewise never coagulates. This coagulation of blood in the ‘living vessels, reminds me of a passage in another writer, whom, though very different from the former, I am inclined to bring forward in illustration of the subject. Dr. Beddoes, in his edition of Brown’s Elements, has the following note: : « Mr. Hunter, who deserves so much praise for ascertaining facts, has been led astray in some of his attempts to establish prin- ciples by a different, but a very curious species of delusion. In treating of that obscure subject, for instance, the coagulation of the blood, he observes, that it sometimes takes place very quickly, as in mortification ; but then ‘ it is to answer some good purpose, and arises from necessity, which appears to act as a stimulus in dis- . posing the blood to coagulate.’ He adds, that by * actions taking place from necessity, effects are meant which arise from some un- usual or unnatural change going on in the parts, and become a stimulus to action. The stimuli from this cause may vary exceed- ingly among themselves ; but as we are unable to investigate them, TJ have included them under this general term, stzmulus of necessity.’ — On the Blood, p. 24.—It may be laid down as a rule in logic, that general terms ought never to be employed, unless we -can substitute](https://iiif.wellcomecollection.org/image/b22009395_0019.jp2/full/800%2C/0/default.jpg)
