CAUTION. 
Mr. T. Fardon (Maidstone) wishes to caution our readers against a naan who is call¬ 
ing on the trade generally, and offering an article called “ Robinson’s Poison for rats, 
mice, etc.” “His practice is to ask payment for half only of the goods he leaves with 
the purchaser, the remainder to he paid for on his next journey. He shows cards from 
Druggists who have been fleeced by him ; he also solicits an address card, that he may 
put it into the hands of the publisher of the local paper, in which he promises to insert 
an advertisement.” Mr. Fardon states that he believes the powder to be extremely 
fattening , as the mice appear to thrive rapidly on it.

TO CORRESPONDENTS. 
An Apprentice (Bristol).—No time has been announced, but it is not probable that it 
can be prepared for publication for some months after the issue of the new British 
Pharmacopoeia. 
Pharmaceutist (London).—Apply to the Secretary, 17, Bloomsbury Square. 
Inquirer (Birmingham).—A paper on the subject w r ill be published shortly in Professor 
Bentley’s series on “New American Remedies.” 
Cupidus. —Read ‘ Selecta e Prescripts,’ Fownes’s ‘ Manual of Chemistry,’ and 
Bentley’s 4 Manual of Botany,’ and apply to the Secretary, 17, Bloomsbury Square, for 
further information. 
Leptandra virginica. —A paper on this subject will be shortly published amongst the 
“ New American Remedies.” 
M. P. S. (Whitechapel).—We can offer no advice with regard to “ window decora¬ 
tion.” An esteemed contemporary has recommended a good model of a leg wearing an 
elastic stocking ; though we doubt the propriety of putting pharmacy on that footing, 
possibly such an ornament might prove effective in your neighbourhood. 
“ Chemicus.” —( 1 ) The article sold as extract of limes is composed of equal parts of 
liquor calcis and oleum amygdalae, scented with essence of lemon. (2) Vol. XIV. p. 207. 
“ Vulnus ” (Market Drayton).— 1 . Wound stone , the same as lapis divinus , which is 
•composed of sulphate of copper, nitrate of potash, and alum, of each 5 iij, camphor 5 b 
The three first ingredients are fused together in a crucible, the camphor being added at 
the end of the process. Our correspondent wishes for a form for waterproof varnish for 
patent leather.- 
D. E. I. (Llangollen).—It is quite a matter of taste ; probably the following would 
answer the purpose:—Essence of bergamot, two drachms ; otto of rose, six drops, to one 
pint of the oil. 
“ Tyro ” (Wilton).—We believe the chalk having the appearance described, is pre¬ 
pared by dropping it when in a semi-fluid state, on some porous material, which absorbs 
the water, and leaves the chalk in a conical form. 
El. C. (Islington).—By means of nitric acid. 
J. Y .—The quantity of sulphuric acid directed to be used in making bipersulphate of 
mercury is more than theoretically required, so that there may be sufficient present to 
compensate for loss by evaporation, and to prevent the formation of a lower compound. 
Several communications are unavoidably deferred until next month. 
Instructions from Members and Associates respecting the transmission of the 
Journal before the 25th of the month, to Elias Bremridge, Secretary, 17, 
Bloomsbury Square, W.C.
