Dessaigne obtained the salt directly from hippuric acid by em- 
ploying oxalic instead of a stronger acid, to effect the decomposi- 
tion. It does not alter upon exposure to the air. : 
- Combustion with chromate of lead gave the following :—0:3600 
gm. gave 0:4227 grm. carbonic acid, which in per cent. express- 
ed, gives carbon 32:02, corresponding with the formula 
which requires 32°43 per cent, of carbon. ; 
Acetate of Glycocoll. 
" , HO, A, 2HO. 
This salt is readily prepared by dissolving glycocoll in acetic 
acid, and adding absolute alcohol drop by drop, till the solution 
becomes turbid, and then afterward at intervals, as the crystalli- 
zation proceeds. ‘The salt analyzed was prepared by adding ab- 
solute aleohol in excess to a concentrated solution of glycocoll in 
acetic acid, (the latter in excess,) by which the salt was thrown 
down. It was then redissolved by heat, and set aside to cool and 
crystallize, by which slender prismatic crystals of great beauty 
were obtained. . 
On combustion with chromate of lead, 02981 grm. gave 0:3644 
grm. carbonic acid and 0-2031 grm. water, which in per cent. 
expressed correspond with carbon 33°33, hydrogen {Bins eRe

Tartrate of Glycocoll. 
By dissolving glycocoll in tartaric acid and adding absolute al- 
cohol in excess to the solution, an oily appearing liquid separates 
and settles to the bottom. Repeated and protracted agitation
