BLOOD.

The quantity of alkalis is greatly diminished, and it is remark- 

 able that the excrement and matter vomited by cholera pa- 

 tients contain alkali. The fibrin is diminished, but the globules 

 are very much increased in quantity. 



Wittstock and Herrman could detect no urea in cholera 

 blood, but Marchand and Dr Nagel detected it in the blood of 

 a cholera patient who had passed no urine for three days.* 



8. Blood in Yellow Fever. According to Steevens the blood 

 in yellow fever is very thick, has a very dark colour, and con- 

 tains less than the usual quantity of salts. This exactly corre- 

 sponds with the state of the blood in Asiatic cholera. 



9. Blood in Typhus Fever. The small bulk of the crassamen- 

 tum, and its want of consistency in the blood of typhus patients, 

 has been long remarked. This would indicate a diminution in 

 the quantity of globules an opinion confirmed by the two fol- 

 lowing analyses of M. Lecanu : 



Water, . 805-2 . 795-88 

 Globules, . 115-0 . 105-00 

 Albumen, &c. 79-8 99-12 



1000-0 1000-00 



10. Mr Gulliver has detected pus in the blood in almost 

 every instance in which there was either extensive suppuration or 

 great inflammatory swelling without a visible deposition of pus 

 in any of the textures of the body. He considers the presence 

 of pus in the blood to be the proximate cause of sympathetic in- 

 flammatory, sympathetic typhoid, and hectic fevers, j 



1 1 . Blood in diseases of the Heart. M. Lecanu made several 

 analyses of the blood of patients affected with diseases of the 

 heart. The following table shows the results of these analyses :
