Dear Joshua:

Itm sorry I don't have any reprints of
J. appl. Phys., 21: 70(1950), but an account of
the present status of our work on osmotic shock
is to come out in the Procedings of the UNDSCO
Conference on Bacterionhage. This is to be pub-
lished in a special issue of the ann. Inst. Pasteur.
which is scheduled to appear sometime this month.
I'll send you a reprint as soon as I have a copy.

It'll be good to have reprints of your latest
work and I'm looking forward to reading them.

Best regards,

~~
