OUR BOOK SHELF. 
Micro-Fungt: when and where to find them. By THos. BRITTAIN. 
Manchester : Abel Heywood & Son. 
This interesting little work, published at the modest price of one 
shilling, will be welcomed by many a field naturalist, who up to the 
present time has been without an inexpensive work on micro-fungi 
to aid him in his rambles. To the student, such a guide book is 
invaluable, and as Mr. Brittain is well known as a collector of 
micro-fungi, and his knowledge of localities so extensive, especially 
in the neighbourhood of Manchester and Buxton, that no words of 
Ours are necessary to recommend it. 
The work had its origin in the papers contributed to THE 
NorTHERN Microscopist by Mr. Brittain; some of them have 
been revised, and an appendix of some value to the student has 
been added.

utility to Microscopical friends. : 
Considerable labour has been involved in its preparation, so as 
to make it not only a list of books in my own library, but by the 
addition of the ‘ Desiderata’ as complete a Bibliography as possible. 
Part III., comprising the literature of the Diatomaceze, for which 
I have had the good fortune of securing the active co-operation of 
Mr. F. Kitton, F.R.M.S., is printed in advance of Parts I. and IL,
