Dear Mrs. Shriver:

1! was happy to teke note of the dinner in your honor, which

Is being held in Sen Francisco on Friday, April 5. Unfortunetely
other matters make [it Inconvenient for me to attend, but |

hope that the occasion might stil! allow for an opportunity to
take an hour or so of your time to discuss some of the progress
we have been making towards the operations of the Kennedy Labora-
torles here.

in addition, | thought you might be personally interested in some
statistics on the seasonal variation of births that we have been
analysing, both with respect to the total population and to the
patients in Institutions for the mentally retarded.

Would there be any possibility of your visiting us In an informal
way on Friday morning?

Yours cordially,

that you might be particularly interested [In this line of
Investigation and it is one where, frankly, your personal
Interest might be a very great help in the mobilization of
the necessary data.
