Providence, March 13, 1934 
Pear Fernalds 1 have yours of the 12th. Your suggestion 
concerning enlarging to x50 instead of xlOO is exactly what 
1 thought of suggesting to you, but finally decided not to 
mention it to you and see what your reaction might be. 
Your suggestion concerning the micrc-Tessar and enlarging 
from that had not seriously occurred to me. There may be some¬ 
thing worth while to try out along this line. If we decide to 
try this 1 think it will be oest to use your outfit rather than 
what we have here, merely because your micro-resear lens stops 
down considerably smaller than do either of our micro-Summar 
lenses here, 
Within the next few days 1 will find out if there is-any 
possibility of using our miero-Stiamar on the bniv. phot©-, 
micrographic apparatus and getting anything amove x4 0T~T f I can 
it will mean that the seeds will’'have'to be "fastened—fce-uj. micro 
slide so that it can be photographed :in a vertical insfg?t(j£of 
horizontal position. After a few tests iwill write you again. 
_ Sincerely, d.i.G. _
