Dear Colleague:
I am happy to participate in the publication of a memorial volume in memory of my friend Academician N. M. Sissakian.
I have written the enclosed paper for this purpose.  It is entitled Orthomolecular Methods in Medicine.  I think that it is appropriate to the volume.
I apologize for the delay in answering your letter, which arrived while I was away from home for two months, on a trip to India and other countries.
With best regards, I am
Sincerely yours,
Linus Pauling
