assimilation had passed off in the urine. In no other*manner can we 
account for this otherwise singular fact; but upon the present view of 
the constitution of gelatine, it is just what we should expect. It is in- 
deed a direct proof, and furnished as it is, by a cautious and intelligent 
observer, who had no theory to sustain, is of peculiar value. 
comparison of the quantity of ammonia in the urine when the pa- 
tient was subsisting upon a flesh diet, and one of gelatine, would be of 
much interest and would, doubtless, show in the latter case, a greatly 
increased excretion of ammoniacal salts.
