280 THE AMERICAN MONTHLY [Oct., 



2000 check signatures. A steel bar plated with Iridium for 

 micrometric purposes, by M. D. Ewell. 



. On the blood of Cryptobranchus and Necturus. On the 

 structure of the teeth and bones of Paleozoic fishes. The ac- 

 tion of leucocytes towards foreign matter, by Edith J. Claypole. 



Prof. W. S. Miller, of Wisconsin Universit}', gave a very full 

 description of the methods of reconstruction of the lung from 

 thin serial sections, many hundreds of which are made about 

 two-hundreths of a millimeter or one twelve-thousandth of an 

 inch in thickness, and sheets of wax one-twelfth of an inch thick 

 or 100 times as thick, which are cut out like the sections, only 

 100 times as large, and are piled on one another till a part of a 

 lung is modeled on a scale 100 times the size of the actual or- 

 gan. Thus the real construction is made much more familiar 

 to the mind of the student. Other organs may be made in the 

 same way. 



The committee on prizes for microscopical investigation ap- 

 pointed last year reported the awards as follows. One prize of 

 $50 to Miss Edith J. Claj'pole, of Akron, Ohio, for her exami- 

 nation of the blood of Necturus and Cryptobranchus; one prize 

 of $50 to Herman Shrenck, of Brooklyn, N. Y., for his investi- 

 gation of the parasitical relations of epiphegus, or beech drops, 

 a plant without chlorophyl, growing on the roots of beech 

 trees (both of these essays were theses for a degree from Cornell 

 University and were copiously illustrated by numerous beauti- 

 ful drawings); one prize of $20 for six microscopic slides, illus- 

 trating the structure of the human spinal marrow, by Wm. C. 

 Krauss of Buffalo, N. Y. 



The society voted to publish 500 copies of its proceedings 

 and also to add abstracts of American microscopical work. The 

 committee on universal screw reported progress and was con- 

 tinued. It was decided not to give a soiree this year. The lo- 

 cal committee gave an excursion on Lake Mendota.
