Mc GrRAw-HILL Book COMPANY: ING.

to Dr. Forrest C. Allen -2- DATE 1/3/38

both sides it was pretty carefully proofread. When
you do run on to any, please let me know, for as you
know, a perfect book without an error has not been
published yet so there must be a few.

With kindest regards,

Sincerely yours,
