extracts already alluded to by us.* * * § Its properties and administration have 
been already alluded to in this paper. 
Tincture of Wild-Cherry Bark. —This is not generally considered a good 
preparation in America, but as it is frequently prescribed in this country and 
elsewhere, we subjoin a form :—Take of wild-cherry bark, bruised, two ounces; 
proof spirit, twenty ounces. Digest for fourteen days, express, and filter; or the 
tincture may be better prepared by the process of displacement or percolation. 
Several other formulas for a “ Wine of Wild-Cherry Bark,”j" “ Ferrated 
Extract,”! u Tablets,”§ etc., have been also given in different periodicals, etc. ; 
for the mode of preparation of which we refer our readers to the authorities 
cited. We have given those which are commonly regarded as the best adapted 
for ordinary use. 
Doses. —The dose of the powder is from thirty grains to a drachm , which may 
be repeated three or four times a day; that of the infusion, two fluid ounces , or 
more, repeated according to circumstances ; that of the syrup, half a fluid ounce , 
to be repeated as above ; that of the fluid extract, a fluid drachm , which is 
equivalent to two fluid ounces of the infusion ; that of the tincture, from two 
drachms to half a fluid ounce. The average dose of prunin, according to Dr. 
Grover Coe,|| as a tonic, is two grains ; as a sedative, from four to eight grains. 
The frequency of the repetition must be governed by the judgment of the 
practitioner. As an expectorant, according to Coe, one to two grains should be 
given every two hours. 
INTRODUCTION OF CINCHONA INTO INDIA. 
The Blue Books that appear under the authority of Parliament contain in¬ 
formation that is certainly not wanting in copiousness and variety ; but true as 
this is, it is rare indeed to find one of these documents replete with information 
belonging especially to the domain of pharmacy. Such however is the case in 
respect to the u Return to an Address of the Plonourable the House of Com¬ 
mons, dated 9 March, 1863 ;—for, ‘ Copy of Correspondence relating to the In¬ 
troduction of the Chinchona Plant into India , and to Proceedings connected with 
its Cultivation, from March 1852 to March 1863ordered by the House of 
Commons to be printed, 20 March 1863.” 
The result of this order has been the production of a folio volume containing 
no fewer than 272 pages and 5 maps, prefaced by a very useful table of contents 
which enables the reader to gain an idea without much trouble of the somewhat 
heterogeneous documents of which the volume is composed. Referring to this 
table we find it to commence with a letter under date 27 March 1852 from the 
Governor-General of India to the Court of Directors of the East India Com¬ 
pany, forwarding a recommendation of the Government of Bengal that cinchona 
plants should be introduced into India. To this succeed a Minute of the Re¬ 
venue, Judicial and Legislative Committee of the Company, and a letter from 
Dr. Royle, strongly urging the desirableness of introducing the culture of cin¬ 
chona into India. Then follow letters relating to the transportation to India in 
the year 1852 of a few plants of cinchona obtained from European botanic gar-
