Dear Mr.Collins, 
I examined the three bottles last night. The Mesocarpus 
is just conjugating,but nothing can be done about the species without 
ripe or nearly ripe spores;if you can presuade it to keep on,we can prob¬ 
ably determine it. The Spirogvra shows no signs of fruit,and also must 
go unnamed. The third bottle is quite interesting. It is a Stigeo- 
clonium,of course,but I cannot make it agree with any species in Hazen's 
monograph. Of course it may be an autumn condition of some known species, 
but I do not think this likely;! think I shall send yourbottle to 
Hazen for his judgement. Did you get a set of this? 
Last Sunday I went over y-ur Gaspe algae,and I think I know them as 
well as I ever shall. If it is any more convenient to you,I can return 
them at once,instead of waiting till next month. 
Very Truly, 
( f^ry ( ^Uc jd. ■
