April, 1847.] 195 



A letter was read from the Rev. Dr. Thomas S. Savage, 

 dated Cape Palmas, Western Africa, January 1, 1847, ac- 

 knowledging the receipt of his notice of election as Corres- 

 pondent. 



Dr. Leidy mentioned, as a remarkable instance of the great 

 fecundity of the Cryptogamia, that in a puff-ball (Lycoper- 

 don) of large size, he counted under the microscope 27 

 sporules in the cubic hundredth of a line, which by calcula- 

 tion, allowing for cellular tissue, makes the total amount con- 

 tained in the specimen, 1,007,669,000,000. 



On motion of Prof. Johnson, Resolved. That a committee 

 be appointed to inquire into the conditions of the bequest of 

 the late William S. Warder, Esq., to this Institution, and 

 to ascertain whether the conditions on which said bequest 

 was made, have not been so for realized that the Academy 

 may be justly entitled to receive the benefit intended by the 

 testator. 



Messrs. Johnson, Pearsall and Carpenter were then ap- 

 pointed the Committee.
