- Test for Strychnine, (Compt. Rend. des Trav., &c., Aug., 1847, 
from Jour. fir Pract: Chem., t. xxviii, p. 511.)—M. Orro employs 
bichromate of potash in place of the peroxyd of lead proposed by M. 
Marchand. This salt added to a solution of strychnine in sulphuric 
acid, produces immediately a beautiful violet color much more brilliant

10. New Methods of separating Nickel and Cobalt.—(1.) Method, by 
H. Rosz, (Royal Acad., Berlin, June 14, 1847, L’Institut, No. '727.)— 
The mode of separation proposed by Mr. Rose for these two metals, 
rests on the fact that in a solution of oxyd of cobalt which contains 
free hydrochloric acid, this metal may, by means of chlorine, be 
Wholly transformed into perchlorid, while the chlorid of nickel suf- 
h gat ea 
ny traces of oxyd of cobalt. After separating the excess of baryta 
from this filtrate the nickel is thrown down by a solution of potash. This
