Dear Josh:

I really appreciate your efforts with regard to the nosition in
Kalekar's group and the correction of my paper. I rezret that the former went
no further because it seemed like a good opportunity. On the other hand I do not
feel like moving just now that my lab is picking un,

Concerning the reprints I will take 100 and I will write the
waberley Press to send them here directly. I will be glad to share costs of
reprints, just let me know the easiest way to do it. I could send you the
amount or settle it with the Press, The number of reovints I will need here in
Chile is low because I plan to send them to the people on my mailing list from
the States. If you plan to send them to vour "customers" it will be better to
compare your list with mine,

I am enclosing here a copy of a letter I sent you just before I
received yours of April 12th. It probably cot lost in the mail beecsuse you haven't
nentionedit. My plans about visiting the States have not changed Sinre that letter
except that I will leave for sure around August 15th and spend a month in Bernie's
lab. I received a President's fellowship from the SAB to do go. liy visiting to
Madison can be arranged later depending on several factors,

Please let me know about the questions on my last letter, specially
about the protoplast's membrone. A paper of Trucco and Pardee in JBC 250, 435
Suzsests that penicillin causes small leaks in the cell wall or membrane rather
than a complete digplution of them, did you read it?

I haven't received yet the isotones from the States to make labeled
TMG. The second shipient seems to be also lost. This is what is called working
under the worse conditions, Luckily I am teeehing a course in Microbial Genetics
and that keeps me busy.

How was the last SAB? Anything exciting?

Best regards to Egther-and” you,
