Dearest, dearest Mumsey,
I hope to goodness this does reach you safe_
ly for it carries in it some very interesting news I think. Dr. Bant_
ing came in as usual last night about 5.30 P.M. and said he had a good
report to make. The insulin which they have been working on for so long
will now be ready for use in a couple of days at the most, and it is the
most powerful that has yet been made. So much so, in fact, that I will
only have to take 1 C.C. at a time when I begin on my two doses, which
will be very soon, I think. He is getting enough of it so that his three
outside patients, Ruth Whitehill, Teddy Ryder [sic], and myself will not have
to change our insulin of a month or so, which is a very good thing as
you know. He was so happy over that part of it, and he really feels that
it is becoming more stabilized all the time. He said, you can tell your
Mother that I can promise her that with this new extract, the next
time you see me I will be on 2240 calories the full amount that a girl
of my age should be having. It will be divided like this 60 of protein
50 of carbohydrate, and 200 of fat. Now if I don't begin to gain weight
on that I will be crazy. The power of this new insulin is so strong
that he expects me to carry all that on only 2 C.C.'s per day, one in
the morning and the other at night. You see what he's so happy about, is
that once he finds out my balance on that, why he has enough insulin on
hand now, so that I won't have to change for a least a month, anyway.
If I once get on 2240 calories, it will be an establised diet plenty
Of calories for me, and maybe then I can live at home with Blanche to
Give me the extract and tend to all my food, for once my diet is ex_
Tablished like that I wouldn't need a doctor unless something went ra_
