and pure blood. Probably some differences would present them- 

 selves, which might lead to important conclusions respecting ic- 

 teric blood. MM. Orfila and Clarion are of opinion that bile 

 exists in icteric patients ; Thenard and Lassaigne that such blood 

 contains no traces of bile ; while Chevreul, Boudet, Collard de 

 Martigny, and Lecanu believe that icteric blood contains the co- 

 louring matter of bile, but none of its other constituents. 



Chevreul found in the blood of icteric children three colour- 

 ing matters, one orange-red, another green, and a third blue ; 

 which he considers as identical with the colouring matters in hu- 

 man bile. Collard de Martigny found in the blood of an icteric 

 woman, besides the usual constituents, 



1. A yellow matter, characterized by its solidity, its colour, its 

 insipidity, want of odour, and insolubility in water and alcohol. 

 It is almost insoluble in muriatic acid, which gradually gives it 

 a green colour. It is very soluble in potash, from which it is 

 precipitated by the acids. It is very little soluble in nitric acid, 

 but assumes from it a green colour. 



2. A green matter, which is soft and elastic, of a deep-green 

 colour, without smell, acrid, soluble in potash, to which it com- 

 municates a brown colour. 



It appears from the analysis of Lecanu, that the blood of per- 

 sons afflicted with jaundice contains fewer globules than healthy 

 blood. He obtained in two different trials, 



Water, ., 828-66 830 

 Albumen, 76-82 65 



Salts, &c. . 14-90 8 



Globules, . 79-62 97 



1000-00 1000 



The mean quantity of globules in 1000 of healthy blood is 132-49, 

 and the minimum quantity 115*85. 



7. Blood in Asiatic Cholera. The blood in this disease has a 

 much greater consistency than healthy blood. It contains a much 

 greater quantity of fixed matter, and much less water than healthy 

 blood. This will appear from the four following experiments of 

 Lecanu :
