Dear Dr. Lederberg,
The authors' address was not given with the "nature note" I referred you to (Duijn, C. van Jr. 1952 A remarkable observation of living bacteria, The MICROSCOPE 9:29-31). However, the "journal" is at the U. Penna Bot.-Zool. Library and the Editor's address is:
Arthur L. E. Barron, Editor
The Microscope
4 New Zealand Avenue
Barbican, London E. C. 1, Engl.
The article is strictly concerned with the observations of an amateur microscopist and would not be of any interest, or, rather, import, alone (since many factors can cause R strains to clump permanently or transtionally) but is of interest in relation to your own studies. I didn't realize that there might be some difficulty in finding this
little "Turtox News"-type leaflet. Perhaps one can obtain free subscriptions for the Wisconsin and Woods Hole Libraries by writing the Editor. But the little sheet has an occasional article of interest to microbial microscopy, and, also, notes such as Duijn's and an equally interesting observation on spontaneous bursting and lysis right in pond water by the late A.C. Ballard (1957 Observations on pond life VI. Paramecium bursaria. The MICROSCOPE 8: May-June: 165-172). One would like to obtain these strains for more careful analysis but Ballard has since passed away and a letter to Duijn via the Editor has been unanswered.
This past month I have begun work with Dr. Demerec in analysis of a series of histidineless strains of Sal. typhimurium by transduction. There are, so far, 8 "groups" by transduction, these matching exactly with grouping by accumulations of metabolites (chromotography). One of the strains is SW950, with which Wilkin and Lacy would have worked. Should you have any strains histidine which are transductible in this system (LT-2) and which you would not mind having included in this study I would appreciate them.
Cordially yours,
Philip E. Hartman
