My dear Dr. Holmes: . 
Accept my thanks for your kind letter of May 28. The 
suggestion it contains is a valuable one, and I will endeavor to 
have it followed up. It may be a little difficult to keep track 
of all the members of icp toton but I will see if this cannot 
be arranged for. 
Believe me, with kind regards, 
Yours very sincerely,
