Dear Torbjorn--

In all likelihood you will have received some official notification
of an informal discussion session to be held in the course of the forth-
coming Bilochenistry Congress in Moscow. You might have some reason to
wonder about my own part in this. If the plane could have been soli-
dified in reasonable time, I would have looked forward to the occasion,
and to the opportusAty it might also give to visit Stockholm; unfor-
tunately, it would be quite impossible for me to leave here for any ac-
preciable period this summer. [Elliot and I are looking forwar.: to seeing
you in October,

Have you had any experience with the Cooke UV lens mentioned in the
enclosed aivertisement? Can you advise how it might compare with the
Zeiss lenses?

I am sorry not? to be able to revert any definite action so far on
the automatic-microscope contract. A number of detailed proposals have been
received back from &he companies, but as far as I know, the contract has
not yet been awarded.

Unless it will adakx delay the transmittal of this letter, I will ve
enclosing some samples of dried silica; and, as you asked, a ganole of the
fluid 4s being sent separately.

We have been having a wonderful experience with the Kleins this sumer,
and will be quite envious of you for having them back.

Cordially,

Joshua Lederbers
