BLOOD. 



283 



The blood taken on the first occasion was of rather a dark 

 colour, the clot was loose, and the serum was turbid and light 

 red, in consequence of the presence of hsematin. The spe- 

 cific gravity of the serum was 1030, and the relation of the 

 clot to the serum as 4^46 : 554. 



The blood contained in 1000 parts : 



Water 797-00 



Solid constituents . . . 203"00 



Fibrin 600 



Blood-corpuscles . . . 92-36 



Albumen with extractive matters . 96-03 



Fixed salts 8-35 



A second venesection was instituted 33 days afterwards. The 

 physical characters of the serum were much as on the former 

 occasion, except that its specific gravity was only 1025. The 

 blood was taken partly from the arm, and partly from the foot. 



The blood from the arm separated into 598'4' parts of clot, 

 and 401 '6 of serum, and was composed of: 



The blood from the foot separated into 5 08" 6 parts of clot, 

 and 431*4 parts of serum, and was composed of: 



Water 778-43 



Solid constituents 

 Fibrin 



Blood-corpuscles 

 Residue of serum 



221-57 



5-84 



125-80 



89-93 



In the blood from the foot, the clot was covered with a buffy 

 coat of about two lines in thickness ; in the blood from the arm 

 there was no indication of that phenomenon. 



Heller likewise analysed the blood in a case of convulsions 

 occui'ring a few hours after delivery. At the period of the 

 venesection there were symptoms of metroperitonitis and 

 endometritis. 



The blood was of a tolerably bright red colour, and sepa- 

 rated on coagulation into 587'3 parts of clot, and 412*7 of 

 serum. The specific gravity of the latter was 1026, and it 

 contained a large quantity of biliphtcin.
