Mr. William Brewster, 
Brattle St., Cambridge, Mass. 
Dear Brewster: 
The box containing the specimens for examination has arrived, 
ana been checked up with the list sent and found to be correct. 
In audition to the specimens already sent, I would much like to 
have your series of Icterus abeillei and Icterus bullocki. 
Will get right at the material on hand in connection with other 
specimens which I have borrowed from other collections, and 
hope to be able to return the specimens with the results in the 
course of a couple of weeks, I have received Mr. Deane's 
‘letter saying that you would be pleased to have me cooperate 
in the paper on Mexican birds in your collection, and I shall 
try to find time to do the portion which I proposed. If I can 
do this I think that altogether the paper can be made an important 
one, for it will have a lot of new matter of interest. Hope 
you are getting on satisfactorily with your work and that we 
will see the Cambridge list published soon, 
Sincerely yours,
