THE MICROSCOPE. 149 



The committee on prizes for microscopical investigation ap- 

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

 $50 to Miss Edith J. Claypole, 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. 



Prof. W. W. Rowlee, of Ithaca, N. Y., read a paper on the 

 aerating roots of Mikania scayideus, a climbing plant belonging 

 to the Composite on the banks of streams, and throwing fine 

 roots upward from its main roots, the sole object of which ap- 

 pears to be to convey air to the interior of the root system. 



In the afternoon the society listened to a demonstration of 

 the use of apparatus for photomicrography by Dr. A. C. Mer- 

 cer, of Syracuse, N. Y., and continued by Prof. S. H. Gage, of 

 Ithaca, N. Y., W. H. Walmsley, of Philadelphia, and others.
