Dear Maryanna: 
Thank you for forwarding my mail, especially since bills were 
involved. I think you should add to the droppings a note telling 
everyone why I'm in Nebraska. The last one only mentioned the 
fact that I was commng out here. I'm working with the 7 ####$## 
families, 2li subfamilies, and 171 genera of feather mites. 
The ifie&ther mite collection here is extremely good. 
Several more things that should be obtained are as follows: 
Wild Microscope Accesories: 
#7032 Filter Exchange T/M20 
#8065 Grey Filter, dia. 33 mm, transmittance 32^ 
# 8066 " " " " » 50 % 
Slide boxes U doz. Black cardboard like last order. 
Glass Sheet 3 1 x 2' \ in thick for use under micro scope 
^ Florescent Lamp for table (clamp-on type,with moveable arm) 
It has warmed up considerably and the snow is melting very fast. 
It's now down to about 6 inches. We may get some more on Sunday, 
however. 
Best regards, 
Binion
