The Correspondence of Thomas Carlyle and Ralph Waldo Emerson, 1834-1872, Vol. I

Excerpt

The trust of editing the following Correspondence, committed to
me several years since by the writers, has been of easy
fulfilment.  The whole Correspondence, so far as it is known to
exist, is here printed, with the exception of a few notes of
introduction, and one or two essentially duplicate letters.  I
cannot but hope that some of the letters now missing may
hereafter come to light.
