mycologists to benefit by his personal acquaintance in the field ; and as joint 
author of the Fungus Flora of Yorkshire, and as Chairman of the Yorkshire 
Mycological Committee, he has greatly helped forward the study of the 
lower forms of plant life with which he is so familiar. In the work under 
notice he has placed all students under a debt of gratitude for the careful 
Fusicladium pirinum, a destructive Parasite on Pears. 
1. Fungus forming minute, velvety, dark-coloured patches on a pear leaf. 2. Fungus 
forming scurfy patches, and causing cracking of the flesh of a pear. 3. Conidiophores 
bearing conidia. Figs. 1 and 2 reduced; fig. 8 magnified. 
way in which he has put in a presentable form all the modern views on 
the subjects referred to in the sub-title, as well as by giving an introduc- 
tion to the comparatively new lines of research. A useful chapter on 
‘Biologic Forms’ is contributed by Mr. E. S. Salmon. Not the least 
valuable part of the book is to be found in the numerous illustrations and 
the descriptions thereof, which from an economic point of view are in- 
valuable. We believe they are all from Mr. Massee’s own pencil, and 
prove him to be a most capable artist as well as a learned author. By 
the courtesy of the publishers, we are able to reproduce one of the 141 
figures. 
The March ‘ Naturalists’ Quarterly Review’ has secured one or two new 
contributors. Mr. Westell (W. Percival, F.R.H.S., M.B.O.U.) informs us 
that in April the ‘ Lambs become s¢vonger,’ in this way, presumably, differing 
from the young of other animals. In the usual praises for new books we 
once again learn ‘that these are quite the finest photographs we have ever 
seen,’ and that ‘this is one of the very best volumes we have ever seen,’ etc., 
etc. The same ‘reviewer’ apologises for describing ‘The Evolution of Man’ 
in a previous issue as ‘The Evolution of W/ars/’ An advertiser (whose name 
we might perhaps guess), wants ‘list of duplicates with lowest prices’ of 
‘finely marked recent clutches of British Birds’ Eggs.’ Is it possible that 
the same individual writes upon the advantages of the Acts for the Pro- 
tection of Birds and Eggs ?
