Dear Professor Parlow: 
Your letter of the 14th and the two 
packages of algae are just at hand and I thank you very much, 
both personally and in behalf of the Garden, for your kindness. 
We are very glad to have all of these specimens. The Columbia 
University set of the Parlow, Anderson, and Eaton exsiccatae 
was defective when Underwood and I arrived on the scene in 1896, 
but the specimens that you now send go far towards filling the 
gaps. Certain things, mysteriously missing from the Columbia 
herbarium, reappeared when the private herbarium of a former 
curator was bought back after his death some years ago, but 
these algae were not among them. 
The best set of duplicates from Coker’s Peruvian algae has 
already gone to Washington, but there still remain some Peruvian 
things of probable interest that I shall hope to send you within 
a few days. And we have a considerable number of duplicate 
Hepaticae from the United States and the West Indies that you would 
perhaps find acceptable. The originals or supposed duplicates of 
these have been named chiefly by Evans, Underwood, and Miss Haynes. 
In our next distribution of duplicate algae from the West Indies, 
I shall be glad to send you one of the best sets. 
Very sincerely yours, 
Professor W. G. Parlow, 
24 Quincy Street, 
Cambridge, Massachusetts.
