Oil of Cloves. ]. Hortvet*) published a communication on experiments about 
direct determination of volatile oil in cloves, by means of distillation in a current of 
steam. In this he starts from experiments made by Reich*®) whose method he modifies — 
350' cc. capacity, in the neck of which a cylindrical flask of 75 cc. capacity is intro- i 
duced which is fitted with a siphon-like side-tube. The smaller flask can be joined to 
a condenser. For distillation purposes 2 g. of cloves are placed in the inner flask 
along with 25 cc. of 20 per cent. salt solution, and 250 cc. of salt solution in t 
outer flask. The apparatus is then closed and connected with the condenser. Whe 
the liquid in the outer flask has reached boiling point, the ‘steam is forced throug 
the mixture of cloves and salt water in the inner vessel, and distillation is continue 
until 225 cc. of the distillate have been collected. The distillate is next shaken ‘int 
separatory with 35, 25, 15 and 10 ce. of ether successively, the united Ge pee 
(American) method of eeenichion: in vith: process the total ether ‘extiable eee
