XXXIV. — On the Fibrin contained in the Animal Fluids, the Mode in 

 which it coagulates, and the Transformations which it undergoes. By 

 Andrew Buchanan, M.D., Professor of the Institutes of Medicine, 

 University of Glasgow, f Continued.) 



VIII. — MIXTURE OF SERUM OP BLOOD, AND SERUM FROM SEROUS CAVITIES. 



Several years ago, I read in this place an account of the singular 

 property which mixtures of the serum of the blood, and serum 

 from cavities lined by serous membranes, possess of undergoing 

 spontaneous coagulation, while neither of the two liquids possesses 

 that property in the separate state. {Med. Gazette, 1836. No. 28.) 

 The development of the fibrin does not take place suddenly, like a 

 chemical precipitation, but goes on gradually increasing during several 

 days, like the development of yeast granules in a solution of gluten 

 and sugar. The fibrinous mass is chiefly made up of filaments, but 

 vesicles are also observed in it, although they never attain the full size 

 of the vesicles in the blister liquid. It is in such mixtures that the 

 particles of fibrin are best seen to arrange themselves in the reti- 

 cular form of cellular tissue. (Med. Gazette, loc. cit.) 



IX. — ORIGIN OP THE CORPUSCLES CONTAINED IK THE ANIMAL FLUIDS. 



The origin of the granules and vesicles contained in the animal 

 fluids is the only subject announced at the commencement of this 

 paper, on which a few observations, are still required.
