Thoracic effusions. I have analysed the fluid obtained from 

 the cavity of the pleura by paracentesis thoracis. It was of 

 a yellow colour, devoid of odour, and consisted of two portions, 

 viz., a thin liquid portion and a gelatinous clot floating on it. 

 The fluid had a strongly alkaline reaction, a specific gravity 

 of 1022*4, and showed, under the microscope, a few primary 

 cells of the size of pus- or mucus-corpuscles. The coagulum 

 was slight in its consistence, and when examined microscopi- 

 cally was found to exhibit the structure of coagulated fibrin, 

 with a few enclosed primary cells ; when washed with water 

 the fibrin was left perfectly white. 



In 1000 parts there were contained :

The fluid, both in its physical and chemical characters, closely 

 resembled lymph. 



[The following analyses of similar fluids have been made by 

 Scherer. In 1 and 2 the fluid was taken at an interval of 

 eight days from the same person. In 3, it should be observed, 

 that the fluid was not analysed till a fortnight after the 

 operation.
