Force, and Spirit.” But enough of this. Practically the best part of the 
work is that which has to deal with electro-metallurgy. In this we find an 
ample Explanation of the various processes; it extends to about fifty 
pages, and thoroughly compensates for the many deficiencies in the other 
parts of this volume. The dictionary of terms will also be found useful. 
SACH’S BOTANY* 
A LTHOUGH we have waited for some years for the translation of this 
-FY book, which was promised to us at an earlier date, we can now under- 
stand the many difficulties which attendedthe labours of the two distinguished 
botanists who have been concerned in the delivery of the English translation 
of this important work. And imprimis let it be distinctly understood that 
at the present moment it is not the intention of the Reviewer to do much 
more than notice the 1 publication of the volume ; for he has felt bound to 
put off his review of so voluminous and vast a work to the October number 
of this journal. And in order to justify his procrastination he must explain 
the fact that the book was not put into his hands till the month preceding 
the publication of this journal. He will, therefore, in the present instance 
merely proceed to indicate the general plan of the book, putting off' his 
criticism to the later season. In the first place, we may observe that the 
Editors have endeavoured to bring the book up as much as possible to the 
times. And this they have done by having the fourth German edition for 
consultation ere they went to press with their translation, and also by in- 
ducing Professor Williamson, of Manchester ; Mr. Sorby, of Sheffield; and 
Professor McNab, of Dublin, to come personally to their assistance in the 
preparation of chapters in which their own researches were especially 
referred to. Of the plan of the book, which we shall only speak of in this 
notice, the following may be taken as a resume. It is divided into seven 
chapters, extending over a space of 850 pages of somewhat small but clear 
type, and of the largest 8vo. size. Thus it will be seen to be no small book. 
It is illustrated with more than 450 woodcuts intercalated with the text. 
In some few cases the cuts are repeated, and in almost all cases they will be 
absolutely new to the English reader ; most of them are from Professor Sach’s 
original drawing, and in all cases where they are borrowed from other 
workers there is the somewhat unusual honesty exhibited of stating from 
whom they have been borrowed. Of the seven chapters of which the work 
is composed the following are the titles, each of which is subdivided into a 
number of sections, and the whole of which are included in the three 
sections into which the book is divided, viz. : — General Morphology , Special 
Morphology , and Physiology : — 1st, morphology of the cell ; 2nd, morphology 
of the tissues ; 3rd, morphology of external conformation of plants. Then
