Dear Mr. Schweinfurth: 
I was considerably chagrinned to learn 
that you had found some type photographs of orchids at the 
Gray Herbarium, but much more so when I was altogether unable 
later to find any trace of them here. Unfortunately we do not 
have a complete list of the later type photos, but I can scarcely 
understand how a set of them got to the Gray Herbarium without 
being mounted here. 
If you will let me have the negative numbers of two or three 
of the prints that you borrowed from the Gray Herbarium, I shall 
look into the matter, and see that you get a set of them promptly. 
Also, I should like to have a set of them herel It is barely 
possible but scarcely probable that Macbride had the prints made 
in Germany and sent them directly to Cambridge, but I do not 
believe so.
