HEXAMETHYLENAMINA. 
Caldwell, Paul, says of the name “ Hexamethylenamina : ” f 
This is one of the things in the new pharmacopoeia which gives a dignified 
air but which seems to disinherit the average physician so far as any benefit 
to be derived from the use of the book is concerned. — Drug. Circ. & Chem.

Wohlk, Alfred, suggests the use of Nessler’s reagent for the detec- 
tion of ammonia, amides, and paraformaldehydes in hexamethylen- 
amine. He asserts that hexamethylenamine itself, even on boiling 
with solution of sodium hydroxide, does not liberate even a trace of 
nitrogen in the form of ammonia. — Ztschr. f. analyt. Chem., 1905,

effect of the sodium chloride that may be present. — Pharm. Ztg., 
Berlin, 1905, v. 50, p. 561.
