acid, adding 10 c.c. at a time and rubbing all the while in the 
mortar. After the addition of all the acid, it is continually 
stirred for half an hour ; it is then further diluted with twenty 
times its weight of water and mixed for another fifteen minutes. 
It is quickly filtered with the aid of a pump and the residue 
washed with dilute hydrochloric acid. The filtrate is received 
in a large test glass and saturated solution of sodium bicar- 
bonate is gradually added, keeping a thin layer of ether on 
the surface of the liquid and stirring all the while till the 
addition of a further quantity does not produce any efferves 
cence. It is allowed to stand for a short time for the complete 
separation of the precipitate. It is then filtered and 200 ce. 
of the filtrate are transferred to a separator and shaken 
with 50 c.c. of chloroform for five minutes. The aqueous layer
