Dear Dr. Wetmore: 
Your letter inclosing identifications of the birds from which 
you took blood smears last spring is gratefully acknowledged. 
I inclose a list of the infected species arranged according to 
parasites found. There was a slide marked ^3 "but the findings 
on it were negative. I am, of course, most interested in the 
infections of Plasmodium since they are more closely related to 
human malaria. I am not sure whether I mentioned that some 
Brazilian workers have described a very interesting species of 
this genus of parasites from Bamphastos toco Miiller. I should 
be especially interested in smears from birds belonging to the 
family to which this species belongs. 
I hope your next field trip is shaping up and I surely envy you 
the chance to go into the field. I hope you will not let my 
interests burden you when you are so hard at work in the field.
