Dear Josh: : g 4 ;

This may be a little late, like most of my letters I seein to get

around to writing, but I did want to drop you a note introducing a
recent graduate of Northwestern Medical School, Gerald Kolodny, who is
starting his internship at Stanford this summer. I imagine he is
already on deck and may have introduced himself already.

Jerry is particularly interested in the field of exobiology and
did a three months "clerkship" with us this winter. Fven though I
explained to him before he came that our excursions into exobiology were
primarily concerned with killing earth microorganisms so that someone
else might examine the Martian ones, he did a very nice piece of work
for us particularly in connection with the Partichrome, of which I
believe you are familiar, and which has of course points in common with
the microscopic scanner you were considering for Mars. We gave him the
dirty task of trying to chase down the sources of some of the particulate
matter in air which takes up the biological stain even though it is
apparently not of microbiological origin. As a matter of fact we are
not certain but that some of it may even be!brganic in origin.

Jerry has a nice background and training in instrumentation and
many other interests beyond that of the usual medical student. He did
not even take too great offense when I made the crack that someone
interested in exobliology should probably be getting a veterinary
rather than a medical degree. I hope he will have a chance to meet you
if his internship does not keep his nose to close to the grindstone.

Sincerely,
