M. C. Lea on reactions of Ethylamine and Diethylamine. 81 
Cerium,nitrate ofprotoperoxyd, light brown precipitate, insoluble in ex- 
cess of the precipitant. 
Glucinum, sulphate of glucina, white, insoluble in excess. 
Zirconium, chlorid of zirconia, white, insoluble in excess. 
Molybdenum, protochlorid, reddish brown, insoluble in excess. 
2 bichlorid, reddish brown, insoluble in excess. 
While the analogies which unite ethylamine to ammonia are 
extremely well marked, the differences in their reactions are also 
very well defined. Like ammonia, ethylamine redissolves its 
toperoxyd of cerium, glucinum, zirconium, protochlorid and 
bichlorid of molybdenum, peroxyd of uranium, bismuth and 
disposition to redissolve in even a large excess of the precipitant

al Ethylamine, like ammonia, has the property of reddening an 
Coholic solution of dinitronaphthaline. 
DIETHYLAMINE, 
the action of nitrate of ethyl upon ammonia is particularly 
well suited for obtaining diethylamine on account of the rela- 
uvely large proportion sbisinstt at once. Further experience, 
Since I published that process, has shown me that the product is 
ane larger than I supposed. ‘The quantity of diethylamine pro-
