Book excerpt: Excerpt from The International Dental Journal, 1893, Vol. 14: A Monthly Periodical Devoted to Dental and Oral Science Fifty years ago the symptoms of inflammation apparently coin cided with what could be seen with comparatively low powers of the microscope. The web-membrane of the frog was fastened upon a piece of cork, hollowed out. A drop of caustic ammonia was applied, or it was touched with a red-hot glass rod, and the result of' the irritation was observed mainly, if not exclusively, in the vascular system of the web-membrane. The current of the blood, which was seen to be normal before the irritation, soon afterwards became irregular and slackened, then oscillating to and fro, and at last arrived at a complete standstill, - the so-called stasis. Most of the pathologists agreed that by the irritation a rapid contraction of the vessels was produced, soon terminating in a paralysis of the walls of the blood-vessels, which latter did not offer any resistance to the pressure of the blood-current. At the same time an inundation of' the tissues of the web-membrane with a liquid had occurred, often mixed with extravasated blood, and after twenty-four hours a num ber of granular corpuscles were seen suspended in the liguid, which was termed exudate. These corpuscles or cells were thought to have originated in the exudate itself, and were named exudate cells. The process of inflammation was evidently a disturbance in the blood and the blood-vessels, and, since all diseases at that time were attributed to a certain mixture or crasis of the blood, the pathologists holding these views were called humoral patholo gists, with whom all diseases were due to a faulty mixture of the blood, - so-called dyscrasia.
