These, together with the publication of ‘Essays on Circulation of the Blood, with Reflections on Blood-letting,’ 1761, gave him a wide reputation.
In 1765 he was elected physician to Middlesex Hospital, and in 1770 was chosen alderman of the Tower ward, a dignity which his professional duties compelled him to resign in 1772.
About this time he removed to Blackfriars and devoted himself chiefly to consulting practice at home.
He died at Stratford in Essex on 26 December 1790, and was buried in the church of West Ham.
He married the daughter of Archibald Maclean, a lady of fortune, who inherited Trevor Park, East Barnet.
