in 1772. Many of its cases went, of course, to the metropolis before that time ; 
but there is, besides, every reason for concluding, that the operation of litho- 
tomy was frequently performed in Norfolk, during all the preceding part 
of the eighteenth century, both from the reputation and extensive practice of 
Mr. Gooch, one of the principal surgeons and surgical writers of his time, who

Operative surgery does not indeed, at this time, appear to have been confined 
to the regular surgeon ; for in the little church of Stoke Holycross, about four
