34 MUSEUM OF COMPARATIVE ZOOLOGY. [May, 



(C.) I have endeavored during this last year, through my 

 personal acquaintances, to enlarge our relations with foreign 

 museums as well as with private friends, in order to stimulate 

 exchange^and assist the Museum in further collecting specimens 

 necessary for scientific investigation. 



In consequence of my appointment as " Geologist and Natur- 

 alist of the Darien Expedition, " I am obliged to stop my work 

 at the Museum for several months ; but I hope that I shall 

 nevertheless be able to do good work for it during this journey ►
