_Prospect House, Clerkenwell._--Will any of your correspondents learned in
old London topography inform me when the "Prospect House, or Dobney's
Bowling Green," Clerkenwell, ceased to be a place of amusement; and where
any account is to be found of one Wildman, who is said to have exhibited
his bees there in 1772. (Vide _Mirror_, vol. xxxiv. p. 107.) And in what
consisted this exhibition? Also, if any other plate of the Three Hats
public-house, Islington, exists than that in the _Gentleman's Magazine_?
Also, if there exists any portrait of Mrs. Sampson, said to have been the
first female equestrian performer, and Life of Sampson, who used also to
perform at the gardens behind the Three Hats?
