cardamoms, reduced the dry articles to a uniform coarse powder passed through 
a sieve of 20 meshes to the inch, put them into a 4-pint wide-mouthed bottle, 
then cut and added the raisins. I then put in 3 pints of proof spirit, macerated 
with occasional agitation for forty-eight hours, then with a covered funnel 
filtered into the 80 fl. oz. bottle as much as would drain off. I then pressed the 
marc and filtered the product. Having returned the marc to the wide-mouthed 
bottle, I added the fourth pint of proof spirit, again macerated for twenty- 
four hours, and pressed and filtered the product. I then added of proof spirit 
sufficient exactly to fill the 80 oz. bottle, which was 5 fl. oz. I have tried the 
same plan with compound tincture of senna, P.L., and with the same results, 
excepting that the waste was oz. instead of 5 oz. of spirit. By this plan the marc 
is practically exhausted, the process is easy, the result certain, the waste small, 
and the time occupied short, requiring perhaps to be extended a little in one or 
two instances, but not more. I have only a common screw-press, and my pupil 
has been the manipulator. Considering the difficulties attending the percolation 
process even under favourable circumstances, I am disposed to think the plan I 
have suggested will prove more eligible. If you think it worth while, you 
can publish this for the benefit of all whom it may concern. 
I am, Sir, yours faithfully, 
Bath, May 24, 1864. John C. Pooley. 
P.S.—I trust that in the revised edition of the British Pharmacopoeia there 
will be some more accurate adjustment of the title “ compound,” as it passes 
my skill to divine why tincture of senna is not , if tincture of cardamoms is, a 
compound.

TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
Sir,—That the process given in the Pharmacopoeia for this preparation does 
not yield a product which will answer the tests there given for its purity, few 
who have tried it will, I think, deny, but, on the contrary, will agree with the 
remark made by Mr. E. Davies, in his lecture on “ Iron,” as reported in the last 
Journal, that u it gave a dark liquid containing protosalt and nitric acid.” 
After various experiments, I have found that if twelve instead of ten ounces 
of hydrochloric acid (sp. gr. 1T7) are used in the Pharmacopoeia process, add¬ 
ing the additional two ounces after the iron is dissolved and the liquid filtered, 
then adding the nitric acid as directed, and evaporating to the bulk ordered, 
that a liquor is obtained which will answer the tests given, and on the addition 
of the requisite quantity of spirit, yield a tincture of elegant appearance, simi¬ 
lar in colour and taste to the Tinct. Ferri Sesquichlor. P.L. 
To those of your readers who possess Mr. S. Darby’s translation of Wittstein’s 
1 Practical Pharmaceutical Chemistry’ I need say no more, they will find the de¬ 
composition clearly and fully explained there ; and it may be sufficient to re¬ 
mind others, that profochloride of iron requires half as much more chlorine as it 
already contains to convert it into perchloride. 
I am, Sir, yours respectfully,
