Dear Dr. Lotmar:
I am glad to have your letter of January 2 about the value of the length of the b
axis of the muscle diagram.
I had already noticed that there was some difficulty in indexing your line (011).
The measurements that we have made on your photographs lead pretty definitely to a
value for b of about 5.3 A instead of 5.65. With this value of b (011) cannot be
satisfactorily explained on the basis of your unit. We have accordingly decided that
the unit has to be changed. At present it seems likely that the only change necessary
is to double one of the other axes. This makes a much larger unit, and the agreement
with the photograph is not nearly so convincing; nevertheless I myself think that
there are good structural arguments to support the choice of the new unit.
We ourselves are trying to make some samples of crystalized muscle, but do not know
whether we are going to be successful or not.
As to the fibrin diagram of Rudall, we succeeded in indexing all of the reflections,
with a unit that has two small axes and one very large one. I have now asked Rudall
to make some more photographs, since he still has the specimen of crystallized fibrin.
I am looking forward to receiving your new reprints.
Sincerely yours,
Linus Pauling:W
