—The third and fourth editions of Sach’s German treatise, and 
Van Tieghem’s French —— of the third, have been n noticed 
which have received high praise. The oe mto 
English is nes like Van Tieghem’s, on the third German edi- 
tion, and one is therefore tempted to first compare English with 
French editi ite Considered as a translation merely, the former 
is superior. It is very close, idiomatic, and as clear as the original. 
In some instances the selection of English words to convey the 
expression involved in a compound German word is most felicitous. 
Considered as an annotated revision, the English edition is inferior. 
The solid pages, for instance those devoted to Tensio m, remain as 
in the German, whereas in the French, skillful paragraphing has 
rendered the whole far easier of reference. The use of signifi- 
cant headings for the tugpee has enabled Van Teighem also 
to give a synoptical table of contents of much value. It has been 
shown in a previous notice that Van Tieghem’s table peda 
clear and wubiaetiin outline of the whole work. Nothing more than 
a list of sections replaces this in the present volume. This lack, 
This conscientious translation is a valuable and timely gift to bo- 
tanical students; that our American fellow students may be more 
ready to welcome it, we present a sketch of the wor. 
The Text-book is divided into three parts: General Morphology, 
Special Morphology and Physiology. The first treats of the 
nature and forms of cells, the formation of cells, the structure of 
nts. Ti 
defined as aggregates of cells which obey a common law 
are next considered with reference to their formation and forms. 
ree systems of tissues are fully described, epidermal, fibro-vas- 
cular bundles, and fundamental. Here are presented comprehen- 
sive studies of laliciferous and wetionlex — sap-conducting 
aap ec spaces and glands. The primary meristem, the unt- 
fo made up of cells, all of which are ¢ capable of dividing, 
is next genstod of in connection with the terminal point of growt 
Here a somewhat confused Bass wees (Hanstein’s) is introduced. 
Frequent cross-references to illustrations further on would have 
made this free from the poe iguity which now “ae it. 
The fault lies, Saanich r,at the door of the German abstract of 
anstein’s and Reinke’s work. The outward shapes of plants, 
differences between structural members and working organs, and 
metamorphosis, come next. Most of this chapter is a literal trans- 
lation of the least satisfactory portion of the third edition. Much 
of it has been rewritten in the fourth German, and for the better.
