to make out with 400 units a week to the middle of August and probably 300 for the last half of August. I promise you that you and your cases will be taken care of at any price but I think you will agree with me that it would be a great mistake to sacrifice our plan of development.

I greatly enjoyed your visit and feel that all of us gained a great deal by getting together here and in Boston.

Yours sincerely,

P.S. I am making it a required condition that no one gets material without promising to submit data to you and us and to give you absolute priority holding their publications til you [?] are ready. So you see I can protect you and you can help me best just now by wiring Mr Lilly an indication that we can start experiments again.
