582 The American Naturalist. [June, 
panied by illustrations of all the genera. This publication is to bear 
the name “Flora of Nebraska” and will be issued in “ parts” as the 
material is ready for publication. It is estimated that twenty-five parts 
of about fifty pages each, will be required to complete this work. In 
August of last year Parts I and II wereissued. They cover the classes 
Schizophycex, Chlorophyces, Coleochæteæ, Rhodophyces and Charo- 
phycex, and are illustrated by thirty-six plates. Part XXII, the 
Calyciflorae, is nearly ready for the press, and will probably appear 
about the middle of the year. The plates, of which there will be 
eleven, are already made, and will illustrate the more difficult species 
and genera.

Pharmaceutical Botany.—A few months ago Professor Sayre’s 
book “ A Manual of Organic Materia Medica and Pharmacognosy ” 
was issued by Blakiston & Co. of Philadelphia. An examination of 
the work, and some use of it in the laboratory show that it is well 
adapted to the use for which it was designed. The introductory chap- 
ters, devoted to an outline of Morphological and Structural Botany, 
will enable the student without other preparation to take up the work 
of the body of the book. The sequence of pharmaceutical products is 
strictly botanical, beginning with those which are derived from the 
Ranunculaceæ, and ending with Irish Moss from one of the Red algæ. 
The descriptions are good, and there are numerous illustrations, many 
of which are very good, while even the cruder ones will prove useful 
to the young pharmacist. Aside from its high value in pharmaceutical 
botany, it will be a useful reference book in any botanical laboratory. 
Professor Bastin has recently added another useful book “ Labora- 
tory Exercises in Botany” (published by W. B. Saunders, Phila.) to 
his well known series. Although not distinctly so stated, it is especially 
suited to the wants of students in Medical Colleges, and those who are 
preparing to take up Pharmaceutical Botany, and for these it will be 
of much service. The numerous illustrations, while often not artistic, 
have the merit of making their meaning plain. The two books might 
very profitably be used together.
