BLOOD. 311 



The girl was 19 years of age, moving in a respectable station, 

 and tall; she exhibited all the symptoms of unmixed, long- 

 standing chlorosis, which appeared in this instance to have 

 reached its highest development. 



On contrasting it with healthy blood, we find little difference 

 in the absolute quantity of fibrin; this constituent is, however, 

 extremely large when considered relatively with the corpuscles, 

 or mth the solid constituents generally. 



The quantities of albumen and of extractive matters and 

 salts do not differ very much from the quantities in healthy blood. 



Andral and Gavarret have analysed the blood in several cases 

 of this disease. It is different in the incipient and in the fully- 

 developed stages of chlorosis. 



In the former the appearance of the patient hardly indicates 

 the presence of the disease ; the face is blooming, rather than 

 pale, and the blood merely exhibits a very considerable decrease 

 of the corpuscles. 



The following numbers give the maxima, minima, and mean 

 of 8 analyses, made during this stage.

When the disease is fully developed the fibrin is sKghtly di- 

 minished, but the quantities of blood-corpuscles, and of the 

 solid residue generally are very much lessened. 



Andral and Gavarret have made 12 analyses of the blood of 

 9 cases of confinned chlorosis. 



I shall give the maxima, minima, and mean results of these 

 analyses ; omitting, however, the cases that were complicated 

 with inflammatory symptoms. 



The blood in which the corpuscles attained their minimum, 

 had the following composition :
