The Ohio Naturalist. 
[Vol. XI, No. 7, 
nonseptate, smooth or minutely roughened at the base, apex 
simply uncinate; asci 5-8, broadly ovate; spores 4-6. On leaves of 
Morns rubra. Oxford, O. October, 1909. 
These species may be distinguished from other Ohio species by 
the narrow, colorless appendages and the 4-7 spored asci; from 
each other, by the number and length of the appendages. 
MEETINGS OF THE BIOLOGICAL CLUB. 
Orton Hall, Jan. 16th, 1911. 
The meeting was called to order by the president, Dr. Dach- 
nowski. The minutes were read and approved. Dr. William E. 
Henderson then favored the society with an interesting and 
instructive address on “Some Recent Theories of Solution and 
Osmosis and Their Biological Significance. He gave an exposi- 
tion of the kinetic theory and contrasted it with the recent solu- 
tion theory of Ivahlenberg. The importance of possessing true 
and definite conceptions concerning osmotic phenomena when 
attacking physiological problems, was made very evident by 
the speaker. 
After a discussion of the address, the society listened to a 
report of the American Association meeting at Minneapolis, by 
Prof. Barrows and a report of the meeting of American physiol- 
ogists at Yale University by Prof. Seymour. In the short bus- 
iness meeting Prof. T. M. Hills was elected a member of the 
society. No further business being presented, the society 
adjourned. 
Orton Hall, Feb. 1.3th, 1911. 
The president, Dr. Dachnowski, called the meeting to order. 
The minutes were read and approved. The first of a series of 
papers on the history of biology was presented by B. W. Wells. 
The early history of biological science was covered down to the 
time of Galen. Mr. B. B. Fulton gave a description of Hocking 
County as a collecting ground, setting forth the wild and primitive 
conditions that still obtain in this locality. Mr. J. L. King pre- 
sented a paper on “Insect Photography,” in which he outlined the 
essentials necessary for success in this special line of work and 
discussed the methods used by experiment stations in illustrating 
their entomological bulletins. A number of lantern slides, made 
from photographs by the speaker, were of much interest. 
A short business meeting was held in which Mr. A. R. Shadle 
was elected a member of the club, after which the society 
adjourned. 
Bertram W. Wells, Secretary.
