Gilycocoll and Bi-sulphate of Potash. 
Gl, 80,+Gl, KO, SO,,. 
By dissolving bi-sulphate of potash in water and adding a 
solution of glycocoll, throwing the whole down with alcohol, re- 
dissolving by heat and setting aside to cool and crystallize, the 
above salt is obtained in semi-opaque prismatic crystals. 
A single determination from the salt dried over sulphuric acid 
gave from 0°6873 grm. of substance 0°6200 grim. sulph. baryta. 
In per cent. giving sulphuric acid =30-94. The formula 
4 4 NO,; 80,+C, H, NO,, KO, SO,, 
requires of sulphuric acid 30-83 per cent. 
Gilycocoll and Bi-chromaie of Potash. 
If glycocoll be dissolved in an aqueous solution of bi-chromate 
of potash, and absolute alcohol be added till the liquid becomes 
turbid, and the whole set aside, in a little time crystals will be 
ormed, 
These, even under the liquid, in a few days become decompo- 
sed, with the deposition of carbon. They were not further ex- 
mined. 
Gilycocoll and Urate of Ammonia. 
Gl, U, AmO, U. a 
' When to a hot filtered solution of urate of ammonia, glycocoll 
is added, in a little time as the liquid cools, long semi-opaque 
needles shoot out from the sides of the vessel. 'The addition of 
alcohol after the first crystallization, causes the separation of a 
second portion. 
Upon dissolving in hot water equivalents of glycocoll and 
urate of ammonia, and cooling, a flocculent mass was thrown 
down, which the addition of alcohol increased, and which, when 
examined with the microscope, proved to consist of exceedingly 
minute prisms. | 
The salt dried over sulphuric acid and burned with chromate 
of lead, gave from 0-2926 grm. substance, 0°3463 grm. carbonic 
acid and 0-1144 grm. water, which equal carbon 32°46, hydrogen 
4-40. The formula 3 
alg H, NO,, 5 N, H, O,+NH, 9, C, N, H, O0,, 
requires carbon 32°30, hydrogen 4°61. se 
imilar flocculent precipitates were obtained from solutions 
glycocoll in both urates of potash and soda. . 
- Gilycocoll and Uric Acid. 
The importance of finding a compound of uric acid that would 
eadily dissolve in water, suggested the effort to combine it with 
glycocoll.
