for Mancbejier and Salford 173 



fix years, though the latter have been unufually 

 numerous, the regiftered births have exceeded 

 the regiftered burials, by an average of 433, 

 annually*. 



* Since this paper was read, the bills of mortality, for 

 the years 1786 and 1787, have been publifhed. In the 

 former year, the regiftered births amounted to 2219, and the 

 burials to 1282; fuperiority of births 937. In the latter, 

 the births were 2256, and the burials 1761 — fuperiority, 

 495. And as none of the diffenters are baptized, though 

 many are buried, at the churches, the proportions of births 

 to burials is ftill greater than is ftated. Taking the year 

 1785 into the account fo as to form a period of three years ; 

 the average annual number of births, during that period, 

 will be 2139, and that of the deaths, 1592. The former 

 multiplied by 26.5 produces 56683, and the latter, by 30.5 

 produces 48556 ; the average of thefe numbers will be 

 52619, and if we allow fifty unregiftered funerals and 150 

 births for the diffenters, and multiply and average thefe as 

 above, we fliall have 2745, which added to 52619, will pro- 

 duce 55364, and may be received as nearly the number of 

 inhabitants in Manchefter and Salford at the beginning of 

 the prefent year.
