Dear Szilards
You may remembering my mentioning Cavalli's name, for someone that

the Institute might consider bringing here. Bertani knows him, and says
he is about 28 years old. Luria may know him also. Cavalli's address is:

Luigi @avalli, Dept. Genetics, University of Cambridge,
44 steurey'd day, Canor&dge, Englani.

As you may have surmised already froa the erasure above, I am a little
muddled as to whether this was mentioned with yourself or Dr. Hogness,but
this should make little difference if the information can be of any use
to the Institute.

ne had a very good tine this trip, and thank you for It.

Sincerely,

Joshua Lederberg
