tial, radial and transverse slices of 150 pieces of trees, and form an 
nvaluable part of the equipment of any botanical museum. Cross 
sections of these woods mounted as lantern slides are also pre-

Photographs of Fungi. We have received from Mr. C. G. 
Lloyd, of Cincinnati, the first set of a series of photographs and © 
photogravures of the larger fungi, prepared by him for distribu- 
_ tion among a limited number of students. The execution of these 
photographs is excellent and they cannot fail to be of great aid to 
mycologists. The species are determined by Mr. A. P. Morgan, 
of Preston, Ohio. Mr. Lloyd informs us that the sets are not for 
sale.

the omission of the anatomy and developmental history, although 
the latter reappears in a review and summary of the Vascular 
Cryptogams. Many additions have been made to the “ special 
studies,” particularly in the portion of the book “devoted to the
