Dear Dr. Kennedy: - 



Please accept my thanks 

 for your check which seemed large to le 

 after reading your note. When our : radium 

 department is established, I shall ask you 

 to call and take a look at it in Ifche autumn. 

 We have a very interesting organization out 

 there and I am hoping we are going to accom- 

 plish something. In fact today I saw some 

 mice whose tumors had been made to disappear 

 entirely, under a peculiar method of X-ray 

 treatment. 



With renewed thanks, I am, 



Sincerely yours,
