ANOTHER "MARTYN". 



BY BRYANT WALKER. 



The arrival in this country of a third l four-volume copy 

 of Martyn's "Universal Conchologist" seems worthy of 

 record, especially as this differs in several details from those 

 that have been described by Ball, Johnson and Dautzenberg. 



It was obtained from Messrs. William Wesley and Son of 

 London, England, and is now in my library. There is nothing 

 to show who had previously owned it. 



The four volumes are bound as two in finely-tooled calf, 



i This is probably a fourth copy, as a four volume set was acquired 

 few years ago by the Academy of Natural Sciences, No. 406 Conch., 

 of the library. EDS.
