Dear Beets:

We have just turned up a few strains which we are
anxious to test for ‘genetic identity with some that you
people have reported. I wonder if it would be possible
to get these for this purpose? I can assure you that
nothing will be published on these strains until checking
back with you. We have just found an adenine requiring
strain in methylcholanthrene treated material which shows
sex~linkage. We would like to test this against adenineless
35293, which is in. linkage group 1. The other two strains
which we would like to have checked is tryptgghaneless, which
apparently is similar biochemically to you € 983,) and a his—
tidineless, ead: We are anxious to know if WH identical
With that reported by Lein et al. We would appreciate the
opportunity of carrying out these tests.

 

Thanks for your letter regarding the symposium meeting.
I shall be looking forward to further information.
