Dear Joe:

     I am curious to know your reaction to the memos that I sent
you in my classified ILLEGIBLE of a few weeks ago.  Have you looked
into the matter enough to have any ideas of the possibilities of
our getting samples on any of these individuals?

     The report that we are preparing is going to be the last word
on the plutonium situation.  Even ILLEGIBLE sample from one or two
of these individuals after this late date will be entirely valuable
data to have.  It will afford a basis of checking the mathematical
expressions that we have derived and will give us some confidence
in our extrapolations.

     I am writing to ask you if you feel the possibility of our
getting a sample in the near future is sufficiently good that I
should hold up the report of the information we already have.

                              Sincerely yours,



WHL/ed                        Wright K. Langham

Dear Dr. Warren:

     Dr. Bassett has been here and helped me finish the semi-final
draft of the Plutonium Report.  We feel that it is essential that
we have your approval on the report before we proposed with its
ILLEGIBLE.  The Rochester people have already seen it and a copy of
a letter from Dr. ILLEGIBLE is included.

     It is our present plan to issue the paper as a joint report
from the Los Alamos and Rochester laboratories.  We think the
classification will be "Secret" and the circulation limited,
depending on Dr. Shields Warren's vistas.

     Please let me know immediately whether or not the present form
is acceptable to you.  Please notice the acknowledgement page,
especially with regard to the statement that you were largely
involved in the imitates of the project.  Do not hesitate to add
any other ILLEGIBLE to the report that you may care to.

     I would like very much to have you return this document with
your comments by July 13.

                              Sincerely yours,




WHL/ed                      Wright H. Langham

Dear Wright:

     You will be pleased to learn that Dr. Shields Warren has
approved your report for CONFIDENTIAL classification and limited
circulation as you requested.

     As to the follow-up on the former Los Alamos employees, Dr.
Durham tells me that the examination form submitted by you was
approved.  It is only necessary that you send such a form with a
suitable letter of instruction to each person to be examined, and
ask that he report to the nearest competent medical facility for
the examination.  Payment of the fees, travel, etc. may be made
through your research budget.  In the case of direct necessity, we
will try to transfer special research funds to you for the purpose. 
This letter therefore is our authorization for you to proceed with
the studies as this basis.

     Dr. Durham has promised to ILLEGIBLE Joe Bowland on the two
Rochester cases.  Have you fully informed Howland of exactly what
you want?  If you will do so, I believe this project also can be
put into operation.

     I hope this information will justify your phone call of this
morning.

                              Yours very truly,



                              Walter D. ILLEGIBLE
