The Companion says, of this intriguingly named fellow, only:
"Primate, [Josiah]. Projector and leatherseller, of Fleet St."---a "projector" being an old term for a "promoter"; perhaps "entrepreneurial speculator" might be the mod equivalent. (Defoe's famous "An Essay upon Projects" was published in 1697.)
