Notice of Book . 
It is much to be desired that the present position of the whole 
question as to the ascent of sap in plants should be brought fully 
before English readers by some physiologist specially conversant with 
the subject. In the present review nothing more has been attempted 
than to point out how complete a revolution in prevailing views must 
be effected by Professor Strasburger’s investigations. 
In conclusion it only remains to congratulate the distinguished 
author on the brilliant success of his latest lines of research, and to 
recommend his book to the careful study of all botanists, as being the 
most important contribution of the last fifteen years at once to the 
anatomy and the physiology of the higher plants. -
