whom the blood in the eighth analysis was derived yielded, on 

 a repetition of the venesection, blood which contained :

Lecanu noticed in the blood of one of these men a solid 

 floating mass, (which, when dried, weighed about 100 grains.) 

 It had a fleshy appearance, and on a section being made it ex- 

 hibited a solid, loosely attached nucleus, of a brick-red colour, 

 in the centre, which slowly dissolved in water. On the second 

 occasion of this patient being bled, the clot presented even a 

 more singular appearance. It was almost entirely formed of agglo- 

 merated clusters of small, round, white, grape-like masses, which 

 were composed centrally of a bright red gelatinous substance. 



[In a case of pericarditis with efiusion, occurring in a woman

 and Rodier, the following results were obtained :

In the first analysis the phosphates were in excess (0-684); 

 in other respects the salts occurred in their normal proportions. 



At the period of the third venesection, the heart-symptoms 

 were much alleriated. The most remarkable feature in this 

 blood is the extreme diminution of the albumen. There was no 

 albumen in the urine.]

The blood usually exhibits, at least when the symptoms are 

 at all urgent, decided indications of hyperinosis. The buffy 

 coat is scarcely ever absent, the serum is clear, and the clot
