866 MC. Lea—Method of Estimating Ethylie Alcohol, 
would be useful, I have oe an examination of the proposed 
method, which i is as follow 
1. Some good wood-spirit, which I had distilled over — soda, 
was gies Pe I tried, however. r, in bo th ways. 
. The adhering liquid was squeezed out as completely as possible 
with a spatula, the _ was liquified by heat, and a thermo 
metric bulb placed in - 
Crystals first sppeuneat --- 102°F. 
The liquid became thick with c Seed at’ ..0° 100

. The crystals of methylic oxalate were freed from a 
liquid as far as could be done by pressure, the mass was lig
