Dear Fred: 
This really means you are part of the "In ,! group. It takes a 
GS-11 or above to get a copy!! Dr. Humphrey is concerned lest this 
report be touching on classified material and wants to limit the 
distribution as much as possible. 
Poor Dr. Ely, he shed a tear when this all went to the printer 
and he couldn't lean on Linda's shoulder anymore!J 
Commit this number to memory, you are responsible for it just 
as for the zip code, room number, driver's license, social security 
number, and my telephone number. 
Bye*
