My dear Dr. Bigelow: 
In your visits of the last three years 
to Briarcliff I feel that you have done 
much through your excursions with the 
girls, your walks and your lectures 
with the lantern slides to develop in 
them a love of nature and the wonders 
of outdoor life, but your lecture last 
week with the microscope projections 
quite transcended anything which you 
have done for us heretofore. In fact it 
seems to me one of the most important 
scientific achievements that has come 
under my notice. 
If you can reveal the secrets of the 
microscope to large audiences of young 
people as you did for us you will cer- 
tainly be making a great contribution 
to scientific teaching. I wish you all 
success in developing your work along 
this line ! 
Yours very sincerely, 
fSiened) Edith Cooper Hartman.
