Ottawa, 18th. April, 1910 
Dear Sir:- 
With this I am sending Ios.449 and 450 of my 
series of mosses. 
The pamphlet will speak for itself. In it 
will he found descriptions of many of the species or 
varieties included in the 450 forms sent. Many of the 
remaining descriptions pertain to those that will he 
sent next autumn. 
Yours truly.
