Dear Dave:

Good to hear from you though | don't think of anyone to recommend
to you. I will keep the position In mind.

The Srskovs In Copenhagen know al! about coli H antigens. They
had to give K-12 a new number (41 1 think). Thelr work Is almost all
published in Acta path. scan., -- or write to them at the State
Serum Institute.

Our own efforts at the genetics of H antigens are in fol (Skaar,
Bernstein, Orskov «= and now Helen Makela, a Finn). Coli Is too
difficult, and Instead we are crossing Salmonellas. The genes for the
antigens are however, in the worst part of the map. The @rskovs are
about to publish some preliminaries on thelr col! crosses.

Glad to hear you're liking Bozeman well enough to refuse at least
some alternatives.

As ever,
