We are consequently forced to assume that the lipochrome 
pigment leaves the body in one way or other, or that it is broken 
down to unknown substances. If then the pigment loses its colour 
or solubility in alcohol and ether, we cannot for the present follow 
its course further. Perhaps it is decomposed, and passes into a 
colourless modification, or it may lose its colonr throngh oxidation 
(as happens under the influence of light). 
We have not succeeded as yet in demonstrating lipochrome 
pigments in urine or in bile.
