150 GOODALE’S PHYSIOLOGICAL BOTANY. 
Botany need only be written in German to deserve the honour of 
translation, and perhaps it is worth while pointing out that German 
text-books resemble the heavenly bodies in at least one particular, 
since they differ widely from each other in magnitude and in other 
attributes. One may imagine the grave surprise of certain German 
authors and their friends—particularly their friends--when the 
news of translation reached them. But far be it from me to say 
than a caution on this matter, lest the charge of 
ingratitude be brought. Botany in this country and in America

Goodale’s can be at once traced almost entirely to the German 
original. While so deeply indebted for material, it is nevertheless 
a distinct mark of progress to find this material in its place in a 
work of independent arrangement and treatment, such as the 
present. 
The book is divided primarily into two parts, containing the 
outlines of the histology of phznogamous plants and vegetable 
physiology respectively. The Introduction contains a short and 
useful account of the appliances used in histology—microscopes, 
nag instruments, reagents, staining agen unt 
me 
the reproductive organs, with a physiological classification of the 
tissues with respect to the division of labour in the plant, and the 
mechanies of tissues. I., which treats of physiology propel, 
constituents, the transfer of water, assimilation, the ges of 
anic matter, growth, movement, reproduction, germination and 
the resistance of plants to untoward influences. T k will thus 
be seen to cover the whole field of plant histology and physiology; 
and with a remarkable amount of detail, considering the limi 
ined. act, one is almost te 
think more highly of it as a storehouse of information than as a 
teaching book,—but this, if a fault at all, is perhaps one of the right

to think, a good one. Such directions are best given personally in 
the laboratory, though these instructions may be of aid to the 
from them. ( in body of the book, however, it may be said 
without hesitation that it consists of the results of accurate and 
conscientious labour. It is very lucidly written, and though a fe 
phrases strike strangely on British ears, it may be after all that 
these are more English than ours would be. Of the two parts of the 
the second is the better done, and at the same time the more — -
