Dear Bill:

Thank you for the trouble you took in your last letter. I realize that
you really could not answer the questions I posed, but I am as sure now as
ever that we have a sympathetic outlook on the publication project. We are,
therefore, happy to return the contracts with our signatures.

The following comments will be assumed to be understood as conditions of
the agreement. While all the business arrangements should be handled with
mi, as a matter of convenience, "GENETIOS AND CHEMOTHERAPY" is a joint enter-
prise of which, as atated on the chapter outline, Luca (Dr. Cavalli) 1s the
senior author, and should be cited as such. In addition, it should be under-
stood (I assume without any question) that section IX, lasts has no
application to research articles or reviews in scientific per » nor
to the work on "Comparative Genetica" which Sonneborn and I have been discussing
with you for some time,

Luca's address in Italy ia: Dott. Luigi Cavalli-Sforza, Istituto Sisroterapico
Milanese, Via Darwin 20, Milano, Italia. However, as stated above, all business
womaunications can be made with me, for my own part, and as agent for him. We.
have agreed to divide royalties equally. When the time comas, any checks can
be written to his order (for his part) and sent to me.

With best wishes,
Yours sincerely,
