CHLOKODYNE AND THE MEDICINE STAMP DUTY.

In speaking of cocoa-nut stearine as a substitute for Theobroma oil, I by no 
means wished to advocate its use. There can be no doubt that the latter sub¬ 
stance is by far the best material for this whole class of preparations, and whilst 
the weather is warm even the five or ten per cent, of lard recommended for 
mixing the powder with in the first place is unnecessary, if not unadvisable. 
The stearine requires more regulation with reference to weather than the cacao 
butter, at least my experience leads me to think so. Still, a dispenser having 
many suppositories to make, may not be ungrateful for the hint, especially if 
soap or any similar substance be a frequently prescribed ingredient. 
There seems to be considerable difference in the quality of Theobroma oil. 
I have by me three specimens, English, French, and German in their origin. 
Of these, the French is the best, though not greatly superior to that from Ger¬ 
many, but either is better than the English. I believe the latter is quite genuine, 
but it has not had the same care bestowed upon its preparation that the foreign 
samples have evidently received.

TFIE PEESERYATION OF LEMONS. 
Sir,—I have for some time adopted a plan of securing fresh lemon-juice at 
all seasons of the year, by the very simple process of varnishing lemons with a 
solution of shellac in spirits of wine. As an experiment, I kept a lemon many 
months in this way ; and as lemons unprotected from external moisture are 
prone to decay, and the juice to deteriorate, I quite believe I have discovered a 
very simple, inexpensive process, by which the medical profession can secure 
lemons during the season of plenty, and lay up with a little care a store of fresh 
lemon-juice for the feverish patient at all seasons of the year. 
To the housewife who desires to use the peel for flavouring, by simply knead¬ 
ing the elastic lemons in the hands, the skin of shellac readily peels off, and 
leaves the rind quite unimpaired. 
I am your obedient servant,

CHLOEODYNE AND THE MEDICINE STAMP DUTY. 
TO THE EDITOR OF THE PHARMACEUTICAL JOURNAL. 
Sir,—You say in your May number, in reply to my question, “ I should like 
to be informed the grounds of distinction between the following labels:— 
“ Barling’s Essence of Peppermint 
Barling’s Syrup of Rhubarb, 
Barling’s Chlorodyne,” 
that “Mr. Barling will perceive that the ground on which the preparation to 
which this correspondence refers is held to be liable to the medicine stamp duty 
is, that it is described as ‘ Barling’s Chlorodyne,’ which implies an exclusive 
right to its preparation ; of course the same would apply to the other 'articles 
mentioned by Mr. Barling.” 
This appeared such a strange doctrine to me,—I, in my ignorance, not being 
able to see the difierence between Barling’s Essence of Peppermint and Essence 
of Peppermint prepared by T. Barling,—that I sent two labels to the Board of
