PULVIS IPECACUANHA ET OPII. 
The Ph. Hisp., V II, includes this preparation under the title 
“ Pulvis ipecacuanha opiatus,” and directs it to be made from 10 
parts each of powdered ipecacuanha and powdered opium with 40 
parts each of powdered potassium nitrate and potassium sulphate. 
The several ingredients are to be thoroughly triturated in a mortar 
until a homogeneous mixture results. — Farmacopea Official Espanola, 
1905, p. 484.

Murray, Benjamin L., discusses the structural formula of quinine 
and presents a chronological bibliography, comprising 68 references, 
on the constitution of quinine and related compounds.- — Merck’s Rep. 
N. Y., 1905, v. 14, p. 301. 
Lyons, A. B., points out that the several tests for the purity of 
the different quinine salts are still open to the very serious objection 
that the same weight of the salt is taken in each case without regard 
to the percentage of quinine in the salt. The test is therefore rela- 
tively more stringent in the case of quinine alkaloid than it is in the 
case of quinine bisulphate. The inconsistency of this was pointed 
out long ago by Dr. Prescott and has been commented upon by others, 
so that the Revision Committee sinned not from ignorance. He also 
points out that the proposition to substitute lime water for ammonia 
water should be investigated, and doubts if there is any good reason 
for embarrassing the assay with the time consuming detail of drying 
u for two hours at 50° C.” — Proc. Am. Pharm. Ass., 1905, v. 53, 
p. 259. 
The report of the Bandeong quinine factory for 1904 shows that 
921,317 kilos of bark have been worked during the year, containing, 
according to analysis, a total of 56,210.34 kilos of cinchona alkaloids, 
which, after deduction of waste, yielded 54,616.66 kilos. The Dutch 
Indian Government has contracted for from 15,000 to 20,000 kilos of 
quinine sulphate this year. — J. Soc. Chem. Ind., Lond., 1905, v. 24, 
p. 1135 (from Chem. and Drugg.). 
An editorial calls attention to the passing of quinine, as evidenced 
by the marked decline in the amount of quinine used within the past 
year. — Am. Druggist, 1905, v. 47, p. 198. 
Reichard, C., discusses the reactions of quinine and cinchonine with 
a number of substances, such as mercurous nitrate, copper oxychloride, 
ammonium persulphate, potassium dichromate, sulphuric acid with 
ammonium molybdate, etc. — Pharm. Ztg., Berlin, 1905, v. 50, p. 314.
