It  may  not  be  amifs  to  premife  a fhort  defeription  of 
the  foil  and  fituation  of  this  city. 
It  is  for  the  moil  part  built  upon  a morafs;  this  is 
more  particularly  the  cafe  in  the  part  of  the  city  lituated 
to  the  Eaft  of  the  river,  which  is  much  the  largeft.  The 
foil  to  the  W eft  of  it  is  more  of  a fand  or  clay.  It  is  divid- 
ed into  two  unequal  parts  by  the  navigable  river  Ouze, 
running  from  N.W.  to  S.E.  Its  fituation  is  in  the  middle 
of  an  extenfive  vale,  well  cultivated,  and  drained  in  gene- 
ral; nor  is  it  kept  very  moift  and  unventilated  by  numerous 
thick  woods.  We  have  no  very  high  grounds  near  us, 
but  at  fome  miles  diftance,  efpecially  to  the  N.  and  E. 
are  high  hills  of  great  extent,  called  the  Wolds.  To  the 
South  there  is  a gradual  defeent  down  to  the  Humber. 
'Our  Waters  are  in  general  hard : we  have  one  or  two 
Springs  of  exceeding  pure,  foft  water.  Some  of  our 
fprings  contain  a confiderable  quantity  of  various  neutral 
falts,  efpecially  the  magnefia  and  Glauber’s  fait,  fo  as  to  be 
purgative:  we  have  two  or  three  pretty  ftrongly  chaly- 
beate. The  higheft  ftate  of  the  barometer  in  the  three 
laft  years  was  30.58;  the  Ioweft,  28.20.  Thermometer 
in  the  fhade,  higheft,  81;  Ioweft,  8.  Having  no  Om- 
brometer, fhall  only  obferve  in  regard  to  rain,  that  in 
1 774  we  had  193  days  in  which  more  or  lefs  rain  fell; 
in  1775,  232  days;  and  in  the  laft  year,  240.
