young. The number during July, August and September averaged 
6,000. Berries and green corn formed the bulk of the diet. 
Prof. Claypole read a short paper on the Potato-rot Fungus, giving 
considerable evidence to show that the infection of the tukers from the 
parasite upon the leaves is not through the stem, but by the conidia 
falling to the ground and penetrating the tubers at the eyes. 
“A Peculiar Case of Spore Distribution,” by F. L. Stevens, cites with 
photographic evidence the distribution of spores of Uncinula necator by 
animal agency, probably a snail. 
“An Anatomical Abnormality in the Human Hand,” by E. W. 
Claypole, mentions a skeleton in which there were two scaphoid bones 
on both the right and left side. 
“Os acetabuli,” by Lynds Jones, describes this important secondary 
element of the os innominatum, which has been ignored by the major- 
ity of anatomists. 
Gerard Fowke gave an account of archeological work in Pike County, 
and Warren K. Moorehead made remarks on a State archelogical map. 
Among the most interesting and important papers was one by Mr. E. 
E. Masterman, of New London, O., giving an account of the finding of 
a grooved stone axe, the material of which was profoundly oxydized at 
a depth of 22 feet in glacial drift or in the top of the boulder clay. The 
circumstances were such that every opportunity of mistake was appar- 
ently eliminated, and there seems to be no possibility of escaping the 
conclusion that the implement is a genuine relic of human workmanship 
which dates back to the later part of the ice age, when streams of water 
from the melting glacier deposited the sheets of gravel and clay which 
cover the plain of New London. Full details of the “ find ” have been 
published by Prof. E. W. Claypole in the November number of the 
American Geologist, to which the reader is referred. 
Mr. Masterman exhibited also several other specimens, but none from 
80 great a depth as the axe. 
A list of Ohio Crambids was given by J. S. Stine, also a paper on 
“Museum Pests and Their Treatment,” and one on “A Few Green- 
house Insects.” E.W. Claypole presented a list of butterflies found in 
Summit County, and a paper on a peculiar katydid. Prof. Kellicott 
described a dragon-fly nymph from a thermal spring in California. 
Prof. F. M. Webster read a long and interesting paper on “ Biological 
Effects of Civilization on the Insect Fauna of Ohio,” and another on 
“The Protective Value of Action, Volitional or Otherwise, in Protective 
Mimicry.”
