    alfo examined the phenomena prefented by the blood of an healthy dog, the better to judge of the date of that fluid in all the fucceeding Experiments. And let me Here obferve, that the Experiments I Ihall have occafion to re- late, were made in the prefence, and with the afliftance of toany worthy friends, Meflrs. Jefle Thomfon, John An- drews my fellow graduate, and Jacob Wagner, junior. They were witnefles to all the phenomena ; and I take this public method of acknowledging my obligations to them for their kind afliftance. EXPERIMENT I. September 6th. 1792. An ounce of blood was drawn from one of the crural veins of an healthy dog, at 15 mi- nutes after 2 o’clock, P. M. it was coagulated at 20 mi- nutes after 2 ; feparation into ferum and craflamentum was evident at 34 minutes after 2. Serum did not change the colour of a piece of paper ftained with a vegetable blue. * EXPERIMENT II. A young dog was kept for the purpofe of ftarvation, and the phenomena were as I ftiall now relate. I there- * The vegetable blue was made life of as ateft, with the view of afeertaining whether the ferum of an healthy animal contain- ed any alcaline fait in a formal ftate, as it is a well dlablifhed fatt that the volatile alcali is produced by putrefaction; and the produc- tion of it is one of the charaCteriftic circumftances of that procefs: the fame teft was made ufe of in the fubfequent experiments, to af- certain whether ferum gained any alkaline properties by the differ- «nt treatment which the feveral animals fufFered.
