DR. BENCE JONES ON CHYLOUS URINE. 
respects, excepting in the diminution of the solids in the serum, the analysis of the 
blood corresponds with that of a case of cerebral congestion given by Andral.

The general results are — 
1st. That the most important changes in the urine take place independently of the 
influence of digestion. 
2ndly. That the urine in one respect only resembles chyle, and that is in contain- 
ing, after digestion, a large quantity of fat in a very fine state of division ; but the 
excess of fat in the urine is not caused by any excess of fat in the blood, for no excess 
of fat was found there. 
3rdly. It appears that some change is produced in the kidney by which fibrin, albu- 
men, globules and salts are allowed to pass out whenever the circulation through the 
kidney is increased : if, at the same time, fat is present in the blood, it escapes also 
into the urine. 
That this change of structure is not visible to the naked eye on post mortem exami- 
nation of the kidneys. Dr. Prout long since demonstrated ; and in a case of this dis- 
ease, which was in St. George’s Hospital, and was examined at Plymouth, no disease 
of the kidney was observed. From the total absence of fibrinous casts of the tubes 
from this urine, it is not improbable that by the microscope a difference may be de- 
tected in the structure of the mammary processes rather than in that of the cortical 
part of the kidney.
