country. Mycology has always been eagerly studied among us, 
but, with a few prominent sone ms the students of it have not 
done brilliant things, to say the least. Nor is this all. This 
sons y has been me stronghold of obstinate and unreasoning 
con lb 3 shown in the clinging to exploded views and the 
fa olin of new wicaaeaeon on no other intelligible grounds than 
their novelty. It is only fair to say that the influence of that school 
has gone. A dozen years ago, for example, there were a few voices 
crying in the wilderness on behalf of Schwendener’s discovery of 
the dual nature of the lichen-thallus. Now it would be hard indeed 
to find a teacher of botany—or an unfossilised botanist for the 
matter of that—who does not accept it. 
his volume is in little more than name a new edition of the 
author's ‘ Morphologie und Physiologie der Pilze, Flechten und 
Myxomyceten.’ The eighteen years that elapsed between the publi-

srernenkicwelss and with what judgment the task has been accom-

on Deoaler points of Prof. de Bary are ready to ac knowledge that

to the course of development of Fungi, the question of ‘eatin

most remarkable chapter in the book. In the next Ae the
