Related article: while larger proportions of the false preparation prevented it entirely.
The authors conclude that the false apomorphine under examination did
not contain much over 20 per cent, of true apomorphine. These correc-
tions of Frerichs's findings, however, do not invalidate the test which he
proposes for determining the presence of foreign alkaloids (trimorphine^
etc.) with which the apomorphine is associated, since the object of the test
is not to determine the presence of apomorphine, but that of the foreign Buy Kamagra Cheap
bases contaminating it. Aside from other considerations, the authors em-
phasize that while apomorphine is emetic in its action, the phaiinacologic
activity of trimorphine is morphine-like, and Buy Kamagra Cheap that consequently the false
article is absolutely unsuited as a substitute for true apomorphine hydro-
chloride. Pharm. Ztg., Iv (i9io\ No. i, 6-7.
Morphine Salts Development of Volatile Odorous Bodies, Buy Kamagra Cheap C. Reichard
having on a previous occasion called attention to the emanation of a
peculiar odor during certain morphine reactions, has recently again
noticed this odor during experiments undertaken for the purpose of estab-
lishing new reactions for Buy Kamagra Cheap morphine. Following up the observation experi-

mentally, he has determined that an extremely faint musk-like odor is
uniformly developed when solution of morphine salts are heated, and that
even the salts themselves emanate this odor when carefully heated. The
intensity of the odor is increased by the concentration as well as the
quantity (extent of surface) of the solution. Speculating upon the cause
of this odor, the author considers it probable that it is due to the minute
volatilization of the morphine salts with the water vapor, or, possibly by
the formation and volatilization of free acid ; but no positive deduction
is at present available. Pharm. Zentralh., 5/ (1910), No. 7, 128-130.
Papaverine Synthesis, Goldschmidt has shown that the constitution
of papaverine, which must be regarded as one of the most important of the
opium alkaloids, is comparatively simple. Am^ Pictet, in colaboration
with A. Gams, has now succeeded in preparing it synthetically, as follows :
By the action of acetyl chloride on veratrol in the presence of aluminum
chloride, acetoveratrol (I) is formed, which yields with nitrous acid an Buy Kamagra Cheap
isanitroso derivatii^es (II) and this is with stannic chloride reduced to
aminoaceloverairoi chlorhydrate (111), Then, starting with vanillin, the
methyl derivatives of which yield hydrocyanic acid an oxy acid nitrite
{IV), this yields on boiling with hydrogen iodide, removal of the methyl
groups, saponification of the cyanogen and reduction of the hydroxyl,
homoprotocatechmc acid (V), which is again methylated and converted
into the chloride (VI). The base (III) and the acid chloride (VI) are
now caused to react on each other and the product of the combination
(VII) by reduction with sodium amalgam in alcoholic solution, Buy Kamagra Cheap main-
tained acid with acetic acid, is converted into the corresponding alcohol
^w^lVIII). To complete the synthesis, the latter is now subjected to
hydrolysis by boiling with phosphorus pentoxide in xylol solution. The
papaverine so obtained proved to be identical in all respects with the
natural base. Schweiz. Wschr. f. Chem. u. Pharm., xlvii (1909), No. 40,

I^ysostigmine An Intensely Fluorescent Derivative. F. Gaubert draws
attention to a body derived from physostigmine whose red fluorescence
surpasses that of all known substances. An aqueous solution of physostig-
mine is allowed to stand for several months until it becomes of a dark blue
color. On adding hydrophthalic acid, a blood-red fluorescence is devel-
oped. The production of this color is at once a distinctive test for either
substance. The crystals of this new body are deep blue in color. Meconic
acid in crystals, silk, cotton, alcohol, ether, etc., are also colored blue by it,
but there is no fluorescence in these cases. On the other hand, aqueous so-
lutions of the crystals sufficiently diluted to be only faintly blue, almost
colorless, by transmitted light, show by reflected natural light a red tint
comparable to that of very fine rubies. Pharm. Joum. and Buy Kamagra Cheap Pharmacist,

372 REPORT ON THE PROGRESS OF PHARMACY.
Scopolamine Influence on the Action of Morphine, k. Friedlander Buy Kamagra Cheap
finds that scopolamine increases the sedative and calmative action of mor-
phine in a remarkable manner, and renders active minute doses wnicb,
alone, would be without effect. On the other hand, morphine acts as an
antidote to scopolamine ; and the latter should never be prescribed with
the former, so that the disagreeable effects of scopolamine, when given
alone, may be avoided. Buy Kamagra Cheap Scopolamine-morphine is specially indicated for
cases in Buy Kamagra Cheap which there is excitement of the central nervous system, or for the
treatment of long-standing neuralgias, where secondary morphinism may
result from the frequent use of morphine alone. Its use is also suggested
in chronic morphinism, since it allows the dose of morphine greatly to be
reduced, and that of scopolamine increased. Habitual morphinism is not
likely to occur with the use of the combined injection. It must, however,
be practiced under assiduous observation, with due attention to the idio-
syncrasy of the subject. As a commencement -^-^ grain of morphine and
^-^ grain of scopolamine may be injected. When the effect of this is les-
sened the amount of scopolamine may be cautiously raised, then, if neces-
sary, that of the morphine. Pharm. Journ. and Pharmacist, Sept. 4, 1909,

Strychnine, Derivatives and Characteristic Reaction. According to
Paul Malaqnin a distinct and characteristic reaction of strychnine in solu-
tion of I : 1 00000 is obtained as follows : To a mixture of i Cc. of the
liquid under examination and i Cc. of pure hydrochloric acid some granu-
lated zinc (just previously treated with HNOs and well washed with water)
is added. After the evolution of hydrogen for several minutes, the mix-
ture is quickly heated to boiling, cooled by immersing the test tube in
water, and a substratum of concentrated sulphuric acid is introduced,
when, in the presence of strychnme, a rose- red ring forms at the zone of
contact of Buy Kamagra Cheap the two liquids, either at once, or after a few minutes. This
color increases in intensity and finally permeates the entire liquid, which is
then heated to boiling. The color so produced is permanent and Buy Kamagra Cheap does
not disappear on boiling, but disappears on the addition of a few drops of
10 per cent, solution of potassium sulphocyanide, and also with an excess
of ammonia reappearing:, however, in the latter case, on supersaturation
with HiSO*. Pharm. Ztg., liv (1909), No. 102, 1007; from Jour, de

Strychnine and Brucine Effectual Separation in Nux Vomica Assays,
In consequence of the unfavorable criticisms regarding the efficiency of
the U. S. P. method of separating strychnine from brucine in the assay of
nux vomica and its preparations, and the suggestion that the difficulties
encountered may be overcome by the presence of nitrous acid in the
nitric acid employed, G. Pinchbeck, after a considerable amount of ex-
perimental work, finds that excellent results are obtained by the employ-
