Dear W3rner t

Dr. Aleuk Bernstein (an English bacteriologtit who recently joined our group)

has been following up Sertic' old observation (apparently quite correct) that

acriflavine will agglutimte flagellated Salamellas of phase 2 but not phase Il.,

'Thds must bespeak a fur&mental chemical difference in the flagella which we

hope to be able to investigate. %s have been tryCng to find prevhm work on

the basis of acriflavine agglutfnntion, or of dye-agglutination of bacteria

generally, but can find @cry little on this sub$xt.  I m wW%ing to you in

the hope gou my have accumulated a bibl%ography and wottlci be wSll%ng to give

us the advantage OR it.

Ge have been using your book in our course this year, and the students seem

to like it very much. The only reason I did not make it an obligatsry assign-

-ment is, as you mq guess, its unreasonable price. I realize 1;hi.s is largely

cut of your hands, but I know of no other channel through which to register

such a comment. I caranot help feeling the production cost am rnwle unduly high

by such features as gloesy paper throughout,

A few typos have been noticed. F. Kauffmann's nme is ~&spelled througha*
(e.g. p.lL62 I think there were some other equally minor ones, but I can't recall

them offhand. Oh yes, -
           Piekarskd (p.39). I a~ sorry you quoted XGB as a publication,
as it is not$&xessible to the public (but not everyone aggea with m). And
Erowning (p. 186) did not work with bacteria. Of ccmr3e 1 only mention these things

as basis for corrections fn further eddtiona if any: as a whale, it locks quite

clezn.

                               Sincerely,
