Not P but Moby-Dick (37)

[Mike Jing]

>From Chapter 53:

Nor would difference of country make any very essential difference; that
is, so long as both parties speak one language, as is the case with
Americans and English. Though, to be sure, from the small number of English
whalers, such meetings do not very often occur, and when they do occur
there is too apt to be a sort of shyness between them; for your Englishman
is rather reserved, and your Yankee, he does not fancy that sort of thing
in anybody but himself.

What does "he does not fancy that sort of thing in anybody but himself"
mean here?
