80 THE AMERICAN MONTHLY. [ April. 
Twelfth Annual Report of the American Postal Microscopical Club. Samuel Lock- 
wood, president. Troy, N. Y. 1887. (pp. 16). 
This report shows that for the past twelve years the Club has given to its members 
opportunities, not otherwise attainable, for comparing notes on, and products of work, 
for the pleasures of companionship to those far apart, and the stimulus of sociability 
and practical advantages of comparison of one’s own work with that of others. ‘These 
advantages, which are only of incidental importance to those favored members who 
are situated at the scientific centres, in the midst of the libraries, laboratories, and 
strong local societies, become of vital importance * * * to isolated workers, sup- 
plying them with a means of contact with the experience of those whose expertness 
can set them a standard of excellence, and whose suggestions can greatly aid them to 
approach that standard.’ The club is doing good work and has a flourishing mem- 
bership. 
Bulletin of the Washburn Laboratory of Natural History, Vol. I, Nos. 1, 2, 3, 4, 5,, 
and 7. By F. W. Cragin. Topeka, Kansas. 1884-1886. (pp. 212, pls. 7). 
These several bulletins, seven in number, the last one dated December, 1886, con- 
tain the collected results of natural history studies bythe students in Washburn College 
and others. They are made up of papers descriptive of various zoological and_botan- 
ical collections, made for the most part as part of the work of the Biological Survey 
of Kansas. The papers are entirely systematic in character, and are lists of species, 
or descriptions of new species, both botanical and zoological. The papers show a great 
amount of activity upon the part of the editor, Prof. Cragin, who has contributed 
numerous papers upon a variety of topics. Papers by Eugene Rau, Francis Wolle, 
Chas. H. Gilbert, W. A. Kellerman, and other well-known writers upon collections of 
the Survey, add to the value of the Azd/etin. Mr.R. E. Call has contributed a large 
number of valuable papers upon the Land Mollusca of Kansas, many of which are 
well illustrated by plates and cuts inserted in the text. The Az//etin bears the evident 
mark of careful work upon the part of its contributors.
