This is a transcription of the letter:
IKW June 26 
Here are the prints you selected from our Annual Meeting collection. I relied on the list of numbers Mr. MacLennan gave me and hope I haven't made any mistakes. Also enclosed is duplicate of a slide of Dr. McKellar, taken by Constantine [Papacosmos], which we thought was exceptionally good.
I hope the moon tables reached you alright and that it wasn't too much of a scramble getting everything ready for the printer. We'll be glad to proofread the moon tables and it would give us a chance to double check the two sets of calculations.
We were all pleased that Dr. Millman agreed to step into the office of President and his acceptance must have been a relief to you people at Headquarters. It has been an upsetting year, hasn't it, with Mr. Kennedy's illness, etc. and climaxed by the death of Dr. McKellar.
I have several more sets of prints to send on their way so I'll close for now.
[signed] Isabel W.
