480 PROCEEDINGS OF THE ACADEMY OF [1898. 



He was elected a member in May, 1874. He served as Treasurer 

 during the years 1893 and 1894 and was a member of the Finance 

 Committee from 1890 to 1893 and again from 1895 until his death. 

 He was Chairman of the Library Committee, and was continuously 

 a member of the Council from his first election thereto in 1881 until 

 his decease. 



In all these positions Mr. Perot was a wise, liberal and devoted 

 friend and supporter of the Academy. His services were given 

 with fidelity and with high efficiency. In all these various relations 

 Mr. Perot not only won the confidence of his associates but by his 

 urbane manner and equable temperament he secured their personal 

 friendship as well. He was a good type of those broad minded 

 and sympathetic business men in Philadelphia and vicinity who 

 have freely given their valuable aid to this institution and have con- 

 tributed so largely to its usefulness and high standing. 



The Academy of Natural Sciences of Philadelphia hereby ex- 

 presses and places on record its appreciation of the value of Mr. 

 Perot's efficient services to the institution and of the great loss 

 which has been sustained by his death.

Occurrence of Oryzomys palustrls in Southern New Jersey. — Mr. 

 Witmer Stone placed on record the capture of two specimens of 

 the Rice-field Mouse, Oryzomys palustris, in southern New Jersey, 

 on Nov. 21, 1898, by Mr. Henry W. Warrington. 



The history of the species is of peculiar interest. It was originally 

 discovered in 1816 by Dr. John Bachman at Charleston, S. C. but 

 was not described until 1836 when a specimen and description were 

 sent to Drs. Pickering and Harlan of Philadelphia for comparison 

 with Ord's Arvicola riparia and for publication if the southern 

 animal proved distinct.
