It has for some time been the general opinion among physiologists, that the fibrin of the blood is liquid during life, and becomes solid onlj when that fluid dies ; and this opinion is based on the well-known experiment, first performed by Miiller, of filtering frog's blood before its coagulation, and thus obtaining the clot separate from the globules, which remain behind on the paper. At the meeting of the British Association at Glasgow, Dr. A. Buchanan exhibited a method of show- ing the same thing in human blood, by receiving it from the vein into a vessel of serum, in which the globules subside before coagulation. The common notion of the change which takes place on coagulation has been well expressed as follows:— T3ioc*v,« i Fluid Serum T winn. Wn.^ / I Fibrin \ VDead blood.

These gentlemen hold, that while of the cor- puscles of the blood the red take no part in the coagulation, and are merely engaged as it were by accident in the clot, from which, by the above mentioned means, they may be artificially excluded; yet the white corpuscles and the molecules which exist in the fiuid, really * Anat.
