Donations for the Library were announced : From M. Dunod,

Dr. Coates presented a paper, by Mr. Hector Orr, on the 

 subject of " Our Monetary System," which was read, and 

 referred to a committee to advise with the Secretaries with 

 regard to its publication in the Proceedings of the Society. 

 Committee consists of Mr. Colwell, Mr. Fraley, and Prof. 

 Trego. 



Prof. Cresson referred to some experiments made by Dr. 

 C. M. Cresson, on the preservation and destruction of vege- 

 table matter, and the influence of temperature upon such 

 material. He finds, in connection with this, that there is a 

 change or increase of temperature produced by the odor of 

 flowering plants, which seems a provision of nature for their 

 preservation from the eff"ects of cold. 



Dr. Rogers mentioned the fact of an increase of temper- 

 ature in the germination of plants, and attributed the changes 

 to the influence of carbonic acid, and its action at various 

 stages of the growth of plants. Dr. Coates and other mem- 

 bers took part in the discussion. 



And the Society was adjourned.
