Although I am aware of the utility of plates to exemplify many parts of this subject, and that one stroke of the pencil will often say more than a page with the pen, yet the enormous expense of engraving has hitherto so confined my opinions to a certain class of purchasers, that they have been either not generally known, or they have been repeated by some without acknowledgment, and misrepresented by others without sufficient quotation. Harestreet, near Romford, 1806.
