GAWAN and Co.'s PATENT TRUSSES, without STEEL SPRINGS.—No. 200, Fleet Street, Temple Bar.—His Majesty's Surgeons, Sir A. Cooper, Bart., and Mr. Brodie, recommend Ladies and Gentlemen, as well as Children, to use these Trusses, as being the most easy and secure. They will not suddenly break even when Gentlemen are riding and hunting, nor when the Poor are engaged in their most laborious occupations. Single Trusses for the Poor at 8s., and much cheaper wholesale.
N.B. To remove every mercenary motive, one month's trial allowed on the retail trade.
