BLOOD. 257 



The decreasing ratio of the corpuscles, and the increasing 

 ratio of fibrin is less striking in this disease than in pneumonia 

 and rheumatism. Andral and Gavarret give the following ex- 

 planation of the first case, in which the high number 148-8 is 

 assigned to the blood-corpuscles. This individual exhibited 

 symptoms of typhoid fever at the period at which he was re- 

 ceived into the hospital. In the second analysis the number 

 is less by 38-6 than before. The symptoms of typhoid fever 

 had now disappeared, and made way for those of bronchitis: 

 the increase of fibrin from 7'3 to 9-3 sufficiently indicates the 

 progress of inflammation. 



In the fourth case the small quantity of solid constituents in 

 the serum was coincident with a highly albuminous state of the 

 urine; the patient, who was about 30 years of age, had for 

 some time been in a weak and emaciated state. The urine in 

 the fifth case, (a debihtated person 28 years of age, whose 

 lower extremities were cedematous,) also contained albumen. 



Andral and Gavarret have likewise analysed the blood in 

 chronic bronchitis. They state that, as the febrile symptoms 

 disappear, and the disease assumes the chronic form, the blood 

 ceases to exhibit a large excess of fibrin, and in fact does not 

 differ in any respect from ordinary healthy blood. 



The same is the case if the chronic bronchitis is combined 

 with pulmonary emphysema. 



The average of five analyses made on the blood of four per- 

 sons suffering in this way, scarcely diff'ers from ordinary blood.

In one of these cases a second venesection was ordered, in 

 consequence of the severity of the dyspnoea. The blood exhi- 

 bited a diminution of 11 in the coi-puscles, of -6 in the fibrin, 

 and of 22 in the solid constituents. 



[Scherer has published an analysisof the blood of a woman 



in the seventh month of pregnancy, who was suff'ering from 



bronchitis, and probably from tubercular phthisis. The serum 



had a specific gi'a\^ty of 1022-69, and contained in 1000 parts :
