Prof.J.Prank1in Collins, 
Dear Mr.Collins, 
T have returned today,by mail,the book of algae 
from Rhode Island. . I have marked the names against the specimens, 
except in a few cases,where determination was impracticable. It is quite a 
representative collection from the locality,well prepared and well preserved. 
Just one specimen,however,I was quite glad to s^. Cladophora rupestris 
was reported from R.I.by Olney and by Rennet,but I have never been able 
to find a specimen. It is here,though,sure enough. 
I am much obliged for the chance of clearing up this rib ubtful matter. 
Very Truly,
