Unknown

The writer has not been identified though he seems to have been at Leyden University, where he studied under Franciscus [Deleböe] Sylvius [1614-1672], who was Professor of Medicine there from 1658 to his death. [Cf. p. 412.] But a careful search through R. W. Innes Smith's 'English-speaking Students of Medicine at the University of Leyden' 1932, has failed to suggest an appropriate name. The author appears to have practised at or near Watford, and on pp. 118-121 he has an entry on 'Epidemic diseases in and about Watford in 1717'. He also speaks on p. 923 of 'my father [in law?] Berrow': a John Berrow was Vicar of Watford who died in 1713.
