Sowerby points out that John Clendinin, a surveyor of 47 Sugar Alley,
appears in the Philadelphia directory only in 1793. She had seen no copy
of the Assistant for collation. The book contains only two series of tables,
as described on the title page.
Jefferson sold his copy of the Assistant to Congress. He did not
order it for the University, whose present copy is a part of the Stone
Collection.
