136  Dr.  haygarth’s  Obfervcitions  on  the 
table.  The  feventh  table  is  compofed  by  finding  the 
proportion  of  inhabitants  in  the  different  parifhes  fepa- 
rately  and  together  in  the  fifth,  to  the  burials  for  ten 
years  recorded  in  the  fixth  table.  In  the  feventh  table 
the  mortality  of  whites  in  Jamaica  is  taken  from  Dr. 
lind;  of  Liverpool  and  Manchefter  from  Drs.  enfield 
and  percival,  who  directed  particular  furveys  of  thole 
towns ; of  the  other  places,  both  town  and  country,  from 
Dr.  price:  fo  that  no  fa&s  can  be  aleertained  on  more 
refpeftable  authorities.  That  the  inhabitants  of  Chefter 
lhould  have  near  an  equal  chance  of  living  to  twice  the

burgh; and  that  no  large  town,  as  far  as  inquiries  have 
been  hitherto  made,  lhould  approach  to  a nearer  propor- 
tion of  longevity  than  as  28  to  40,  are  aftonifhing  fa£ts. 
The  center  is  by  far  the  moft  falubrious  part  of  the  city; 
the  average  of  deaths  within  the  walls  is  only  1 in  58,  a 
degree  of  longevity  much  fuperior  to  what  in  general  is 
recorded  even  of  the  country.  The  parilhes  which  in- 
clude the  fuburbs,  viz.  St.  Ofwald’s,  John’s,  Mary’s,  and 
Trinity,  are  of  the  largeft  fize,  and  comprehend  many 
central  parts  of  the  town  which  are  undoubtedly  as 
healthy  as  any  of  the  reft,  but  they  alfo  contain  all  the 
out-fkirts,  which  confequently  muft  be  much  more  un- 
healthy than  appears  to  be  the  general  average  of  deaths
