NOTICES TO CORRESPONDENTS. 
Coroners’ Juries. 
A. E. S. (Liverpool).—The question of liability to serve on juries has been repeatedly 
referred to in this Journal, and the Act relating thereto will be found at page 95, 
Vol, IV. (New Series), from which it will be seen that a Pharmaceutical Chemist is 
exempted from serving on any juries whatsoever, “All Registered Pharmaceutical 
Chemists are absolutely freed and exempted from being returned and from serving upon 
any juries or inquests whatsoever, and shall not be inserted in the lists to be prepared 
by virtue of the principal Act or this Act.” 
B. \V. (Halifax) wishes to know the composition of the “ Chemical Fly Papers.” 
“ Pharm. Brit." —(1.) For recovering spirit or ether from preparations in which those 
liquids are used in the process but are not finally left, a copper or tin dish with a still-head 
that fits on as the lid of a saucepan does, may be employed. When used for recovering 
the volatile liquid, the joint may be luted with linseed-meal. (2.) There is no autho¬ 
rized formula for pepsine wine, but it may be made by macerating medicinal pepsine in 
wine in such proportion that there shall be a dose of pepsine in a teaspoonful of the 
product. 
“ Saffron .”—The sort of mill known as the cannon-ball mill answers well for making 
mercurial ointment. 
“ A Student .”—In making medicinal infusions the temperature of the water and the 
time of maceration are regulated with a view to the solution of what is required and 
the rejection of what is not required of the solid ingredients. 
“ Apprentice .”—The Pharmacopoeia which is in use both for the Major and Minor Ex¬ 
aminations, is the British Pharmacopoeia, but candidates ought by no means to be un¬ 
acquainted with the composition of the more important medicines of the London Phar¬ 
macopoeia, and they should also possess a competent knowledge of all drugs which are 
in common use, whether included in the Pharmacopoeia or not. An acquaintance with 
the new system of chemical notation is desirable, but is not, we believe, at present re¬ 
garded as compulsory. 
“ An Assistant ” (Cheltenham) wishes to know the best means of preserving liquorice 
root. 
“ Duhius ” (Ripley).—In reply to the question in our last number, Mr. T. Burkenshaw, 
of Tickhill, says, “I poisoned a hedgehog last summer with two scruples of prussic acid 
of Scheele’s strength. I had kept the animal in possession some time previous (along 
with two others) taking great notice of their curious habits, so know it to have been in 
a good state of health at the time of the experiment, and believe a smaller quantity 
would have dispatched it.” 
“ A Correspondent .”—(1.) No. (2.) Dr. Attfield’s ‘ Pharmaceutical Chemistry.’ 
J. E. G. (Derby). —Acetate of Iron .—Take of Sesquioxide of Iron 1 part, Acetic Acid 
(sp. gr. P066) 6 parts. Digest for three days, and filter. 
“ One who wants to become a Pharmaceutical Chemist .”—The paragraph is correct and 
clearly worded. Our correspondent should write to the author, who would, doubtless, 
gladly give explanations or advice in cases of difficulty. 
11 .—There is no difference in the supposed varieties of Potassce Chloras. 
K Cl + 3 (Ca 2 HO) + 3 Cl 2 = K Cl 0 3 + 3 Ca Cl 2 + 3 H 2 0.
