toa method recommended by Kemp, that of mixing chlorate of 
potash with sand. 
The method which I finally adopted was suggested by Prof. 
Mulder. 'The substance to be burned is mingled thoroughly in 
a silver crucible with two or three times its bulk of caustic soda ; 
layer of the soda is placed upon the surface of the mixture so as 
to entirely prevent the escape of any sulphur without coming in 
contact with it. Heat is applied very gently, and through the 
water of the soda the whole mass in the crucible becomes semi- 
fluid. The heat is gradually increased until this water is driven 
off, and the remaining carbon is burned away by the addition of 
a few crystals of nitrate of potash. The mass is now dissolved 
in water, and after the addition of an excess of hydrochloric acid, 
the sulphur is determined by baryta in the usual way. 
_ Lat first attempted to determine the phosphorus also by this 
Method ; after the sulphate of baryta was separated, ammonia 
was added until the solution became neutral, phosphate of baryta 
(2Ba O+PO*) immediately fell, this was separated, weighed, 
Steady boiling are necessary. I attempted an improvement by 
dissolving the substance in nitric acid ina platinum basin, and 
ture however always exploded with great violence. | 
Having thus mentioned the methods adopted, I now proceed 
to the results of my analyses, and will begin with the legumin of 
almonds. 
Ihave made in all of these substances two or three distinct 
Preparations, and have varied a little the mode of obtaming them
