    f h tH’Jk^tyfvviM\} ON THE COAGULATION OF THE BLOOD Dr. Buchanan showed some specimens of hydrocelic serum, the fibrin of which was coagulated by means of a few fragments of the icashed clot of blood added to it sometime before. The coagulated masses were transparent and tremulous, like calf-foot jelly, and so firm as to admit of being inverted on a plane surface without altering their shape. Dr. Buchanan made the following observations in explanation of the phenomenon. The experiment exhibited to the Society, and the analagous ex- periments mentioned below seem to me important, as serving to rectify some prevailing opinions as to the essential properties of Fibrin, and the part which it plays in the coagulation of the blood, and certain other physiological processes. They are still farther interesting to me, as enabling me to correct some erroneous views of the constitution of the blood which I entertained, and which having been made public in the first volume of the “ Proceedings of the Society,” I feel it a duty to rectify. The opinions commonly entertained by physiologists and chemists, to which allusion has just been made, are, that fibrin has a spontan- eous tendency to coagulate: that this spontaneous coagulability is a characteristic property of fibrin, by which it is distinguished from albumen and casein: and that the coagulation of the blood, and of various other animal fluids depends on the spontaneous coagulation of the fibrin which they contain. My experiments, on the other hand, show, that fibrin has not the least tendency to deposit itself spontan- eously in the form of a coagulum: that, like albumen and casein. riBRINIFEEOUS LIQUIDS.
