THE NEW RUPTURE SOCIETY, FOR THE RELIEF OF BOTH 

 SEXES AFFLICTED WITH HERNIARY COMPLAINTS AND 

 PROLAPSES. 



With a view to interest the public in the success of this 

 institution, it is thought necessary to submit to them the 

 following concise statements, with respect to the nature of 

 those calamities for the relief of which it is intended. The 

 facts here mentioned, it is presumed, will be amply suffi- 

 cient to excite attention and to induce inquiry. 



It has been estimated that at least one person in fifteen is 

 ruptured : but among those classes of the community which 

 •are much exposed to laborious employment, the average 

 may be fixed at one in eight or nine. The proportion, how- 

 ever, of sufferers from this disease, is incomparably greater 

 in places of which the situation is low and damp, and the 

 atmosphere relaxing. The committee of this institution, 

 which the public are now requested to patronise, have been 

 credibly informed, that, in souk; particular parishes, this 

 proportion may be computed at even a fourth of the labour- 

 ing population ! 



This complaint is not confined to any particular age or 

 F 4 sex.
