PHARMACY AT THE DUBLIN EXHIBITION. 
continue the trituration, gradually adding rose water and the spirit of 
nutmeg, so as to form 20 fluid ounces of an uniform emulsion, which pre¬ 
serve. When required for use, add the sulphate of iron in the proportion 
of 3| grains to each fluid ounce. 
The next formula respecting which I would offer a few words, is that for 
Mucilago Tragacanthse. This preparation is rarely wanted, and never, I be¬ 
lieve, kept ready prepared. It is, moreover, much too thick, and twenty-four 
hours is a longer time than can generally be allowed for preparing it. If a 
mucilage containing tragacanth only is required, which in the presence of so 
convenient a preparation as the Compound Powder is very questionable, the 
following formula will be found to afford a good result. 
MUCILAGO TRAGACANTHJ2.

To the water contained in a pint bottle, add the tragacanth, agitate briskly 
for a few minutes and again at intervals until the gum be perfectly dif¬ 
fused, which will occur in about five or six hours. 
PHARMACY AT THE DUBLIN EXHIBITION. 
There is perhaps no other art which is not better represented in the Interna¬ 
tional Exhibition, now open at Dublin, than that to the interests of which the 
pages of the ‘ Pharmaceutical Journal ’ are devoted. This is, I think, readily 
explained by the fact that the London Exhibition of 1862 gave to the manufac¬ 
turers of chemical preparations, all that could be desired in the way of publicity, 
while the extensive display organized under the auspices of the Pharmaceutical 
Society, left little to be done in that of illustrating the position which Pharmacy 
now occupies. Then, again, the very products which generally excite the greatest 
interest, are, for the most part, not those which are representative or even new; 
but those which—like the codeia bowl of Messrs. Smith, of Edinburgh, or the 
mass of calomel of Messrs. May and Baker in the Exhibition of 1862—cost much 
trouble to prepare, and are not easily transported to a distance. Yet, there is 
the British Pharmacopoeia with all its new—if not improved—preparations, 
which have as yet never been collectively illustrated. How comes it that no 
pharmaceutist has thought it worth the trouble to bring together a complete 
collection of these ? Nevertheless there is—when one throws aside the catalogue 
and really seeks in earnest for matter, which, if not very closely connected with 
Pharmacy, yet has some bearing upon it—a great deal that is interesting and 
some that is novel. It must be understood that I speak now only of the British 
Department of the Exhibition, to which I propose to confine this notice. As far 
as I can judge from a very short ramble through the foreign courts, Pharmacy 
is much better represented in them than in the home section. 
Perhaps the best idea of the way in which the medico-chemical art—if I may 
be permitted to coin a phrase—is represented on the part of the United King¬ 
dom, will be obtained if I take from the Official Catalogue the few pithy notices 
which must be the key-words to all that I shall have to notice as far as Phar- 
macy, pure and simple, is concerned. It is always well to have a fixed plan, 
and to adhere to it as closely as may be. Having given this short list of the 
pharmaceutical exhibitors and the products which they exhibit, I propose first 
to speak of such specimens as appear to deserve notice, and then to describe such 
other objects in the Exhibition, as from their connection with chemistry and
