and some of its Products of Decomposition. 65 
When the solution had become very concentrated, fine needle- 
formed crystals filled the whole mass. They deliquesce readily 
in the air. | 
A single combustion with chromate of lead, gave from 0:4992 
gm., 03055 grm. carbonic acid = 16°58 per cent. of carbon. 
The formula C , H , NO,, KCl, requires 16-92 percent. of carbon. 
Gilycocoll and Chlorid of Sodium. 
_ A concentrated solution of glycocoll and chlorid of sodium 
m water, gave upon addition of absolute alcohol and standing a 
length of time, crystals containing both of the above mentioned 
mgredients. A quantitative examination was not made. 
Gilycocoll and Bi-chlorid of Tin. / 
_By dissolving glycocoll in the least quantity of water, and ad- 
aoa bi-chlorid of tin, after a time, crystals containing both in- 
tedients of the solution are formed. ‘They were not more par- 
ticularly examined. 
Gilycocoll and Hydrochlorate of Berberin. 
Gl, Ber, HCl. 
This salt is obtained by adding a hot solution of hydrochlorate 
of berberin in spirits of wine, to a concentrated solution, in ex- 
cess, of glycocoll in the same menstruum. + Upon cooling, the 
hole mass becomes solid, and consists of myriads of the most 
delicate needles, of a brilliant orange color and bitter taste. The 
salt may be washed with water, as glycocoll is therein readily sol- 
uble, while the salt of berberin is not. 3 
The salt dried at 100° C. [212° Fah.] and burned with chro- 
Mate of lead, gave the following results: 
0:1563 grm. substance gave 0°3485 grm. carbonic acid and 
0-0826 grm. water, which expressed in per cent. give carbon 
60:80, hydrogen 5:87. These correspond with the formula 
? , H, NO,+C,, H,, NO,, HCl, 
Which, containing berberin with the constitution given by F'leit- 
mann,* requires 60-21 per cent. of carbon and 5-03 per cent. of 
hydrogen, 
Glycocoll and Potash. 
. PY dissolving glycocoll in diluted caustic potash and evapora- 
Ung to Syrup consistence over a water bath, crystals in the form 
ong delicate needles, containing the two ingredients, are form- 
res They may be rapidly washed with spirits of wine. ‘They 
deliquesee rapidly in the air, even over sulphuric acid. ‘Dissolved 
‘0 Water, the salt gives a very strong alkaline reaction. It was 
° turther examined.
