Of this singular contract, which is signed, "Robert Logane of Restalrige" and "Jhone Neper, Fear of Merchiston," and is dated July 1594, a facsimile is given in Mark Napier's Memoirs.
His usual signature was "Jhone Neper," but in a letter written in 1608, and in all deeds signed after that date, he wrote "Jhone Nepair."
The form "Neper" is the oldest, as John, third Napier of Merchiston, so spelt it in the 15th century.
Napier frequently signed his name "Jhone Neper, Fear of Merchiston."
Neper, Baron of Mercheston, near Edinburgh, and told him, among other discourses, of a new invention in Denmark (by Longomontanus, as 'tis said), to save the tedious multiplication and division in astronomical calculations.
