and much of the morphology is really found in this section. The 
preceding 226 pages are devoted to an exposition of the external mor- 
phology of plants; an introduction to microscopic technique and vege- 
table anatomy; and an account of the structure of some of the more 
important drugs. 
The morphology of the vegetative organs of the lower plants is dis- 
missed with a few pages, a treatment which is only justifiable in con- 
sideration of the small part these plants playin medicine. Even from 
this point of view, it might well have been longer; what there is is 
good. The discussion of the morphology of the members of the 
higher plants is a compact and clear presentation of, for the most part, 
modern ideas, with comparatively few survivals of useless terminology. 
We cannot say so much for the account of the morphology of the flower 
of angiosperms in the systematic part, where Dr. Warnecke does not 
seem to be so much in touch with modern conceptions. 
The section on anatomy (leaving out of the special anatomy of the 
selected drugs, regarding which we are not competent to express an 
Opinion) is again a well selected and well arranged compendium of the 
Wee histology. Dr. Warnecke has shown good judgment in 
_/4S put in and what he has left out. The treatment of second- 
pili atin for example, so important for an understanding of the 
pee most ot the barks, stems, rhizomes and roots which come
