 INTRODUCTION. 



I HAD originally selected for the address 

 which it is my duty and privilege to give 

 to-day a very different subject f from that

 been asked for.| Of the multitudinous

JThe Third International Zoological Congress, 

 (Leyden Sept., 1895), appointed an International 

 Commission of five members to study the various 

 codes of nomenclature in use in different countries. 

 This commission is composed of Dr. Eaphael 

 Blanchard (France), Prof. Carus (Germany), Prof. 

 Jentink (Holland), Dr. Sclater, (England), and Dr. 

 Stiles (United States). Dr. Stiles requested the ap- 

 pointment of an American Advisory Committee. This 

 Advisory Committee has now been completed and is 

 made up as follows :
