Oil of Calamus. As a note of warning we may here mention a sample: of calamus— 
“oil submitted to us for analysis by a Leipzig firm. It sailed under the proud designation: a 
of Oleum Calami, Ph. G. V. but was found to be a concoction containing i.a. a safroly 
camphor oil fraction as well as traces of salicylic acid and apparently also benzoic ~ 
acid. Its suspiciously weak odour showed that there was but little calamus oil in the 
mixture. Of the chemical constants an abnormally high ester value and insufficient 
solubility betrayed the character of the sample; specific gravity was within recone 
limits and optical rotation only very little too low: diso 0.9612, a) -+ 8°, acid v. 0.9, 
ester v, 139.1, soluble in 5 volumes and more of 90 per cent. alcohol. For comparison _ 
purposes we may mention that pure oil of calamus is soluble in almost any proportion 
of 90 per cent. alcohol and possesses a saponification value from 6 to 20. Unfortunately — 
we were unable to determine the kind of ester which had been added, as the quantity — 
of oil submitted for analysis was insufficient, but the comparatively large amount of 
‘acetic acid which was separated in the process of saponification points to an acetate 
having been used; it is probable that the above- nents acids were contained in’ 
the sample in the form of esters. . . < 
Another sample, of the same origin, which was examined by us quite recently, 
was also found to be adulterated in the most baretaced manner. Re es
