PHARMACY AT THE DUBLIN EXHIBITION. 
Foreign States. —From Austria are sent Wax, both bleached and un¬ 
bleached; the former is cut or shaved in small pieces, with the view of in¬ 
creasing its apparent whiteness, so that it is impossible to compare it fairly 
with the bleached wax of home production, E. Loehnert (Bohemia) has a 
good collection of dextrines, “gum substitutes,” and other modifications of 
torrefied starch. 
Belgium. —Bruneel and Co. (Ghent) have a good series of products from 
the destructive distillation of wood. De Cartier (Anderghem), Iron Minium, 
obtained by calcining red haematite and levigating the product. The “iron 
minium ” is said to be in many respects a better paint than either red lead or 
oxide of iron, prepared from the sulphate. Blondiau (Alost) sends Glucose, 
a substance which is now prepared in vast quantities from farina, and finds a 
ready sale in this country, being probably used as a source of alcohol. 
France. —MM. Baudesson and Houzeau (Reims) furnish to the Exhibi¬ 
tion an extensive series ef chemical products and specimens of “ photography 
on tissues,” concerning which latter no information has been afforded. 
E. Dubose and Co. (Havre) contribute specimens of liquid and solid ex¬ 
tracts of dye-woods. Of these I have examined those of Logwood and Per¬ 
sian Berries, which are of very good quality, and are nearly totally soluble 
in cold water. The other French exhibitors of chemical products are MM. 
Tissier (Conquet), Roques and Bourgeois (Ivry), and Odepli (Luxeuil). The 
last-named shows Extract of Pomegranate, a preparation which, by the way, 
might very advantageously be introduced into English pharmacy. The value 
of pomegranate bark as an astringent in diarrhoea, although popularly appre¬ 
ciated, is not sufficiently recognized by physicians. 
Italy. —In this department there are of course several exhibitors of Sul¬ 
phur, of which many of the specimens are in very fine crystals. The chief 
contributors of sulphur are S. Barbagallo (Catania), the Duke of Brolo 
(Palermo), and the proprietors of the Romagna Sulphur Mines (Bologna). 
Oils of Lemon, Orange, and Orange Flower, and of Bergamot, are sent by 
the firms of Mellisari (Reggio) and Antonnio (Catania). Citric Acid, not 
very remarkable for whiteness, is shown by A. Campisi (Catania). A very- 
extensive series of chemical products, presenting, however, nothing very re¬ 
markable, is contributed by Cancliani and Co. (Milan). It includes, however, 
Borate of Manganese, used in the preparation of drying-oil, and said to be far 
more effective for this purpose than oxide of lead. 
Dr. Bandiera (Palermo) sends a styptic fluid, which, under the title of 
Hcemostatic Water, is said to be very effective in controlling hemorrhage. 
This is, I presume, a solution of the double chloride of sodium and peroxide 
of iron, which was described by, I think, Dr. Phipson, in the ‘ Chemical 
Hews,’ some time since. 
A very interesting series of specimens is contributed by the Convent of 
Servite Friars (Sienna). The monks appear to turn to good account the car¬ 
bonic acid evolved from the mineral springs of Chianciano, and manufacture 
by its aid very good Bicarbonate of Potash and Bicarbonate of Soda. They 
make also “ Protocarbonate of Iron” by double decomposition of the sulphate 
and an alkaline carbonate, and then drying the product in an atmosphere of 
carbonic acid. I had hoped that the carbonate thus obtained might really be 
something more than sesquioxide, and that the Serrite Friars might be able 
to supply English pharmaceutists with a product which we have no oppor¬ 
tunity of preparing for ourselves, but I was not a little disappointed to find, 
on examining the “protocarbonate,” that it contained but a trace of carbonic 
acid, and was little, if at all, more deserving of the name than the oxide of 
our own Pharmacopoeia. 
The other specimens of interest in the Italian department are those of
