Hello everyone - an update;
Sorry if I've sent anyone off on a wild goose chase for the second of
the two quotes (the one I paraphrased).
Apparently it's from "The Habits of Good Society: A Handbook of
Etiquette for Ladies and Gentlemen" (James Hogg & Sons, 1859) and
runs thus;
"A man,... whether he aspires to be a gentleman or not, should learn
to box. There are but few rules... Strike out, strike straight,
strike sudden. Two gentlemen never fight; the art of boxing is
brought into use in punishing a stronger and more impudent fellow of
a class beneath your own."
Not a boxing manual at all I'm afraid.
No joy finding my first as yet.
Regards,
John.
