Heller observes that lie lias often been able to detect bill- 

 plisein in tbe blood of pneumonic patients when there have 

 been no other indications of a disordered state of the hepatic 

 functions. 



In pneumonia venosa the buffy coat is absent. (Schonlein.)] 



y. Pleuriiis. 



Never having analysed pleuritic blood, I shall merely give 

 the results obtained by Aiidral and Gavarret. 



That the blood in this disease may exhibit considerable dif- 

 ferences, will be seen by the following cases. 



1st stage. Pleuritis in its early stage, before any effusion has 

 occurred. In two cases of this nature, Andral and Gavarret 

 found the quantity of fibrin increased to 5*8 and 5*9. 



2d stage. Pleuritis not yet advanced, but effusion. 



Andral and Gavarret found that the quantity of fibrin varied 

 from 4 to 6 in eight cases of this nature. 



3d stage. Pleuritic effusion of some duration ; no fever. In 

 four cases of this nature, in which effusion had occurred during 

 well-marked pleuritis, from two to four months previously, the 

 quantity of fibrin was increased, less certainly than in the pre- 

 ceding cases, but still in one instance rising as high as 4' 8, and 

 averaging about 4. 



Hence it follows that the fibrin is increased in the blood in 

 pleuritis, especially in the acute form, accompanied with fever ; 

 the increase, however, is not so decided as in pneumonia, bron- 

 chitis, and (as we shall presently see) in acute rheumatism. 



Nassei states that the buffy coat is particularly characteristic, 

 and seldom absent in pleuritic blood.^

* The huffy coat was absent 9 times in 35 cases in which blood was extracted 

 during pleuritis, 3 times in 11 cases of pneumonia, and twice in 5 cases of bronchitis.
