Dear Joshua:

I am afraid thet there are no longer any
reprints available of the 1944 paper on transformation.
It has been some time since we scraped the bottom of the
barrel on this reprint.

On referring again to your original letter,
I ses that I did jump to an unwarranted conclusion in
assuming that you were considering the inclusion of the
Mellon paper in your volume. I am sorry that I discussed
the paper under this misapprehension, but the statements
that I made would stand in any case.

Sincerely yours,

(fet What,

Maclyn McCarty, M.D.
