Dear Joshua,

Thanks for the note regarding Carfter's translation of Koch's

papers. I had seen it just in time to mention it in my Koch biography
Y before typesetting was completed. It will be a useful addition to the

Koch literature, especially for those who don't read German. Most of

these papers had been available in translation, but in widely scattered

sources. My biography is just about to go off to the printer, and we
a hope for a July publication date.

I have an article under review at Microbiological Reviews on a history
SL of the bacterial nucleus. I'm not certain that the journal will accept it,

as it isn't quite their current style, but the editor (at least) likes

it. I felt that I needed to consider the nucleus before getting down

to details on the genetics. I begin with late 19th century bacterial

cytology and end with Kellenberger and Cairns.

ye Have you seen the recent book by Saap on cytoplasmic inheritance? I assume
you have, since you are extensively cited. Having spent the 1960's in :
Bloomington in a lab near Sonneborn's, I found it quite interesting Loy
reading, albeit somewhat repetitious. There were also a few errors,
but overall it provided a useful complement to the traditional genetics
histories. Of those, the one I have found the most interesting and useful
was Carlson's biography of Hermann Muller.

Thanks for keeping me informed of recent literature, etc. After my

Koch book goes to the printer, I'll be taking the summer off for some
other work, and then back to the history in the fall. I'll send you a copy
of the Koch as soon as it is available.

With best wishes,

. }
