representatives, in natural size and also much enlarged, of the seeds of 100 
of the most troublesome species. These illustrations are from the water- 
color sketches of NoRMAN CRIDDLE, and will enable the farmer to identify 
readily most of his plant enemies, either while they are growing in the field 
or while polluting his seed grain. 
The book is well printed and strongly bound, which, together with its 
other admirable qualities, makes it a valuable addition to the literature of 
economic botany.—GeEo. D. Futter. 
A text-book of pharmacognosy.—A fourth edition of KraEMER’s Text- 
book has appeared.3 It is “intended for the use of students of pharmacy, asa 
reference book for pharmacists, and as a handbook for food and drug analysts.” 
Such a statement indicates that the volume does not fall within the province 
of a botanist for review, and yet the material presented is of great interest to 
botanists. Part I (pp. rags is entitled ‘‘Botany,”’ and comprises a presenta- 
tion of all the great groups, “outer morphology of angiosperms,” ‘“‘inner mor- 
phology of the higher plants,” “classification of angiosperms yielding vegetable 
drugs,” and “cultivation of medicinal plants.”’ Of course this is botany for 
the pharmacist, and Dr. KRAEMER is in a position to know what the pharma- 
cist needs. Only the first chapter, dealing with the great groups, really per- 
tains to the non-pharmaceutical botanist. Perhaps it makes no difference 
to the students concerned, but the very antique flavor of the presentation of 
the great groups is somewhat surprising to the modern morphologist. Part 
II (pp. 383) is entitled “Pharmacognosy,” and deals first with crude drugs, 
and then with powdered drugs and foods. Part III (pp. 88) is entitled 
“Reagents and technique”; and part IV (pp. 38) deals with “ Micro-analysis.” 
The volume is certainly a thesaurus of information for the pharmacist, 
and doubtless will have great influence upon the progress of pharmacognosy 
in this country. There is abundant evidence, also, of an immense amount 
of painstaking labor on the part of the author, who is to be commended for 
his many years of faithful effort to organize and advance his subject.—J. M. C.
