Dear Professor Leopold, 
Than1 youf or your note of December 15th. 
You have not given me any final answer regarding your own participation#

final 
in the preparation of the book. As I don't expect a/ answer from you 
yet, I wish you wJould think over the entire matter a little while longer.

To speak quite frankly,andvdt)4ll due respects to mr. Hickey, it would 
be an inestimable advantage to us to have your nanB on the published 
book. 
If by ill-chance you should see yourself 
obliged to give me a negative answer, only then would I want to go into 
further details about alternate possibilities. Won't you write me 
again in a few weeks? 
Yours sincerely, 
Harold Strauss
