Lloyd, John Uri, points out that — 
The Eclectic School of Medicine employs only the natural benzoic acid, made 
from gum benzoin, and rejects that urine made regardless of reaction. In the 
commercial world very little of this natural acid is distributed, owing to its 
expense. It can be safely said that if one wishes benzoic acid made from gum 
benzoin instead of urine he will necessarily be forced to give the subject his 
personal attention. The same is true of the benzoates made therefrom, includ- 
ing both common and rare in medicine. 
The editor adds : 
Attention should be directed to the fact that most of the commercial benzoic 
acid of to-day is made from toluene. — Pharm. Rev., 1905, v. 28, p. 298. 
Douglass, Malcolm E., in notes on materia medica, suggests its use 
in concretions in the joints, affections of the bladder, nocturnal 
enuresis, and in rheumatism. — Hahneman. Month., Phila., 1905, v. 40,

Fendler, G. (Apoth. Ztg., v. 20, p. 757), discusses the turmeric 
reaction for boric acid and outlines a method recommended as giving 
an admirable test paper in so short a time that it is not necessary to 
keep a stock. — Abstr. Pharm. J., Lond., 1905, v. 21, p. 617. 
Goske, A., points out that the generally used turmeric paper test 
for boric acid and boric acid compounds is not free from possible 
objections in that it is too delicate, table salt that is not entirely free
