 a remarkable milk-white turbidity, not caused by fat in a state 

 of suspension, but (as shown by the microscope) produced by 

 numerous minute solid granules, which, by diluting the senim, 

 and then allowing it to rest, were collected, washed, and analysed. 

 Thev were not soluble in alcohol or in ether, but dissolved

The blood in the 3d analysis was taken from a robust man, 

 aged 55 years, in the first stage of granular degeneration, and 

 sufFering from anasarca. The urine was very albuminous, but 

 not bloody : the serum was milky, and abounded in urea. 



The blood in the 5tli analysis was taken from a man aged 48, 

 suffering from anasarca and continued fever. The kidneys were 

 in the first stage of granvilar degeneration; the urine contained
