om the liver of an adult three to six days after death. On 
examination Gorup Besanez found the opalescence to be due 
to glycogen ; and he gives the following method for preparing 
it pure: The opalescent liquid from the liver is freed from al- 
buminates by acidulating with acetic acid, heating rapidly to 
boiling, and filtering from the coagulum ; it is then mixed 
with twice its volume of 90° alcohol ; a bulky precipitate falls 
which, after standing some hours is collected on a filter, washed 
Out with alcohol, dissolved in water, heated to boiling with a 
few drops of acetic acid—which causes the separation of a 
very strongly starch or inulin. Water dissolves it toa strongly. 
opalescent liquid, not cleared by boiling. The solution is col- 
0 
tic acid, becoming rather clearer by this treatment ; thus agree- 
ing with the observations of Hensen, Scheerer, and Lochner, 
but in opposition to those of Bernard and Lehmann. The 
‘trong opalescence of the liquid prevented any determination 
of its rotatory power. On analysis, his assistant Klinksieck 
obtained numb
