and some of its Products of Decomposition. 65 



Whgn 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 04992 

 grm., 0-3055 grm. carbonic acid = 1658 per cent, of carbon. 

 The formula C 4 H 4 N0 3 , KC1, requires 16-92 percent, of carbon.

Glycocoll and Chlorid of Sodium. 



A concentrated solution of glycocoll and chlorid of sodium 

 in water, gave upon addition of absolute alcohol and standing a 

 length of time, crystals containing both of the above mentioned 

 ingredients. A quantitative examination was not made. 



Glycocoll and Bi-chlorid of Tin. 



By dissolving glycocoll in the least quantity of water, and ad- 

 ding bi-chlorid of tin, after a time, crystals containing both in- 

 gredients of the solution are formed. They were not more par- 

 ticularly examined. 



Glycocoll and Hydrochlorate of Berberin. 



Gl, Ber, HC1. 



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 

 whole 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. 



The salt dried at 100° C. [212° Fah.j and burned with chro- 

 mate of lead, gave the following results: 



0-1563 grm. substance gave 0*3485 grm. carbonic acid and 

 00826 grm. water, which expressed in per cent, give carbon 

 b 080, hydrogen 5-87. These correspond with the formula 



C 4 H 4 NO,+C 4f H,, NO,, HC1, 



wnicn, containing berberin with the constitution given by b leit- 



jnann * requires 60-21 per cent, of carbon and 503 per cent, of 

 hydrogen.
