Thank you for your letter dated March 6, that I found on arriving at Cold Spring Harbor last month. I knew that Stocker had
tried transduction by phage in Salmonella but without success. I have been more lucky and I got colicinogenic transfer by
phage lysates. It is however not very efficient and selection of the transformed cells is at the limit of my technical possibilities.
I am now trying transduction by phage with coli strains.
I am now arranging for my travel in June. I expect to arrive in Madison by June 9th at 1 or 2. p.m. and spend the afternoon
with you. I hope that this date will be convenient for you because my program is very tight as I have only one month to travel
to California and back, and it would be difficult to alter the plans.
Are you going to the Chicago Meeting of the S.A.B.? I shall be there and hope to meet you.
