 history books, and specimens of all kinds are in constant 

 use by its readers. Asa medium of exchange between those 

 having specimens it is without a peer. Place your 1917

 thing over fifty dollars and gained a number of regular and worthy cor- 

 respondents who I would perhaps have known by name only had it not 

 been for The Oologist."
