 My dear Mr. Deane: 



I think I told you that I hope to get off to 

 South America soon after the first of June. One of the places 

 on my proposed itinerary is Arequipa, Peru, where Harvard Uni- 

 versity has an observatory. I believe that Professor Campbell 

 is in charge, but whether he is there or not I do not know. 

 Are you acquainted with any of the people stationed at Are- 

 quipa? 



Yours very truly, 







Research Associate.
