MEETINGS OF THE BIOLOGICAL CLUB. 
Orton Hall, March 7, 1911. 
The meeting was called to order by the President, Dr. Dach- 
nowski, and the minutes of the preceding meeting read and 
approved. The President then introduced Dr. Win. McPherson, 
of the Department of Chemistry who addressed the society on 
The Formation of Carbohydrates in Plants. The address was a 
review of the speaker’s recent paper in Science on this subject. 
He gave a summary of the theoretical and experimental results 
accomplished up to the present time and emphasized the necessity 
of the botanist and chemist working conjointly in the solution of 
the intricate problems presented. The address was followed by a 
lively and interesting discussion. 
The next topic of the evening was the second of a series of 
papers on the History of Biology. The period from Galen to 
Lamarck was treated in a very interesting manner by Miss Marie 
McLellan. 
No business being presented the society adjourned. 
Bertram W. Wells, Secretary. 
Orton Hall, April 4, 1911. 
The President, Dr. Dachnowski, called the meeting to order 
and the minutes of the preceding meeting were read and approved. 
Dr. R. J. Seymour then read a paper on A Theory of Nerve 
Activity, in which he presented an interesting theory proposed by 
Herring. This theory supposes the nerve fibres to be qualitatively 
and inherently different. The hypothesis was discussed in its 
various aspects and it was pointed out that while not yet proven 
the theory had no weighty arguments against it. 
Mr. Clcll L. Metcalf, followed with the third of a series of 
papers dealing with the history of biology, discussing the period 
from Cuvier to Pasteur. His paper was particularly valuable in 
that it made prominent a number of the less well known biologists 
of that period. 
Mr. A. R. Shadle reported that he had observed a pair of 
evening grosbeaks on March 19th, at Delaware, Ohio. This, it 
appears, is one of a number of observations made this year of this 
western bird in the eastern Mississippi Valley and New England. 
No business being presented the society adjourned. 
Bertram W. Wells, Secretary.
