1 Howarp, F.L.S., F.R.M.S, F.R.H.S., Member of the Pharma- 
ceutical "em of Great Britain, and of the Botanical Society of 
France, etc. London: L. Reeve and Co. 1869. Pp. x. 44, 
with three coloured Plates by Tuffen West. 
Seven years have elapsed since the appearance of Mr. Howard's 
*Nueva Quinologia of Pavon, and now we have the above work 
fully sustaining the author's reputation as an accomplished chemist 
and botanist. Mr. Howard is one of those lovers of science, unfortu- 
nately by no means numerous, who stick with persevering zeal to the 
investigation of a particular branch of inquiry with a view to its eluci- 
dation; and in the present instance, such has been the application of 
our author that he is justly considered to be one of the greatest quino- 
logists living. Would that others would produce such valuable 
monographs on little-known subjects! and the result would help to 
render economie botany less perplexing to the student than it now is. 
The present work treats on the result of the acclimatization of the 
Cinchone in India, under Mr. M‘Ivor, who is as successful a cultivator 
as Mr. Broughton is a quinologist. Mr. Howard well observes of 
these gentlemen, ** The Indian Government have been fortunate in the 
choice of servants to whom the practical carrying out of the details of 
this great scheme has been confided, and I am glad to think in this 
‘most recent instance they have been equally successful." 
The work consists of four parts. 1. Microscopical Observations on 
the Plates; 2. Chemical and Microscopical Investigations ; 3. Appen 
. dix; 4. Addenda et Corrigenda. 
- In the * Microscopical Observations’ we have some remarks on the 
 Strueture of those barks which have been “ renewed," and having an 
important bearing on physiological botany. The plates, for the ac-
