MEETINGS OF THE BIOLOGICAL CLUB.

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. Wm. 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 w^as 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

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. Seymotir 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 w^hile not yet proven 

 the theory had no w^eighty arguments against it. 



Mr. Clell 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 ntunber of the less well known biologists 

 of that period. 



Mr. A. R. Shadle reported that he had observed a pair of 

 evening grosbeaks on Alarch 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 Valle}' and New England. 



No business being presented the society adjourned. 



Bertram W. Wells, Secretary.
