= am writing for your opinion 8s to the desirability

of having @ m per at the Extranuclear factor seetion of the
Uutation Conference on the relation of viruses to these

factors. As You Imow,the COs stary in Drosophila (L'Heritter
and Teisster) ts belng interoreted as due to a virus and

some people have sugsested that kapva and Lindesren's
cytogenes ars viruses. Do you think 16 worth while to ore-
sent an analysis of the whole situation with a view to
clarifving thinking on the subject? If you think thts

would be worth doing,i'd like you to undertake 1b. You

lmow the tima limits. Our section is llkely to have more

‘speakers than the 4 or 5 Demeree sugsested,so I think we

should stick closely to the 20 minuts limit and make it

even less,if possible.

Let me have your answer as soon 4s convenient and,

“4f you decide to undeptake this mper,let me have your
‘subject and the time you will require.

With very best greetings of the season to you and
