April 23, 1907.My dear Miss Gowing:-
The urine came was quite satisfactory, and I am glad for you to keep on your same diet and quantity of soda. I am sending you some Proto Puffs. You can have one of these daily as a substitute for a casoid biscuit, not in addition to the casoid biscuit.
When you next send a specimen of urine, if you will also send some of the huckleberries which you canned, I will have them tested, and let you know whether they are suitable for you.
Sincerely yours,
Elliott P. Joslin
