John Bull's Sister Peg, the Scotch, in love with Jack (Calvin).
John had a sister, a poor girl that had been
reared ... on oatmeal and water ... and lodged
in a garret exposed to the north wind.... However,
this usage ... gave her a hardy constitution....
Peg had, indeed, some odd humors and
comical antipathies,... she would faint at the
sound of an organ, and yet dance and frisk at
the noise of a bagpipe.—Dr. Arbuthnot,

of John Bull
