13To Thomas Jefferson from Charles Willson Peale, 18 July 1802 (Jefferson Papers)
When I wrote last, the 10th. Ult., the head of a Common Ox then before me was so imperfect as to lead me into an error about the width of the horns—since I have procured a head from a Butcher, who did not brake the Scull, which cleaned and free’d from the horns, I find the measurement from pith to pith of the Horns is Inches.
