The chief was entrapped by Argyll, tried, and condemned to death. On the jury which condemned him sat John Napier.

A revised edition appeared in 1611, wherein he still expressed his intention of rewriting it in Latin, but this was never accomplished.
Mathematics, as well as theology, must have occupied Napier’s attention from an early age. What he had donein
