A. (Kensington ).—Syrupus Quince lodidi. See page 392. 
Jl. ]f, (Alderley).— Ess. Rhei Dulc. Probably the following formula for Extractum 
Rhei Fhddum, U. S., would give a satisfactory result; and the Senna might be prepared 
in a similar way:—Take rhubarb, in moderately fine pow r der, 16 oz. troy ; sugar, in coarse 
powder, 8 oz. troy ; alcohol, a pint; diluted alcohol, q. s. Moisten the rhubarb w r ith 4 oz. 
of the alcohol, introduce it into a conical percolator, press it gently, and pour upon it 
the remainder of the alcohol. When the liquid has disappeared from the surface, 
gradually pour on diluted alcohol until a pint of tincture has passed. Set this aside in 
a warm place until reduced by spontaneous evaporation to 6 fl. oz., and continue the 
percolation until 2 pints more of the tincture have been obtained. Evaporate this by 
gentle heat to 6 fl. oz., then add the sugar, and, when this has dissolved, add the reserved 
tincture, and continue the heat until the whole is reduced to the measure of a pint. 
J. W. G. —We can give no opinion as to “ business prospects ” in the colonies.
