Hothrock, Lesley, Frazer and Kane, with special reference 

 to the occurrence of abnormal rings in timber, Mr. Price 

 desired it to be remarked that Dr. Rothrock's important 

 practical discovery was the direct result of the practical use 

 to which the American Philosophical Society had put its 

 portion of the Michaux Legacy, as the minutes of the last 

 few years show. 



Dr. Frazer communicated a paper entitled : " Some Com- 

 parative tables showing the distribution of Ferns in the 

 United States," by Geo. E. Davenport, of Medford, Mass. 

 (See page 605.) 



Dr. Frazer presented the report of the Special Committee 

 on a Memorial to Congress, which was approved, and the 

 Officers were authorized to sign the Memorial and transmit 

 it to Congress. The Committee was discharged from the 

 consideration of that part of the subject which related to 

 the Light House Board. 



The President reported that he had received and paid over 

 to the Treasurer $132.75, being the quarterly interest on the 

 Michaux Legacy last due. 



On motion of Mr. Price, the expense of preparing the 

 illustrations of Dr. Roth rock's paper was charged to the 

 Michaux Legacy fund.
