a difference of only between 3 and 4 grms., ^.e., between 10 and 13 
per cent., very little more than the results of Rubner show for a 
healthy man. Of the 170 grms. of proteids absorbed, only 97 
grms. were changed to urea, i.e., about the amount which, according 
to Voit, is required for a normal diet. Corresponding to the re- 
maining nitrogen, we find the excretion of 69 grms. of the globulin 
substance. 
Was this 69 grms. of the proteid of the food retained to make 
good the loss, or was it, having undergone some change in the liver, 
excreted as a globulin with the characters above described ? 
That it is derived, somewhat directly, from the proteids of the
