iiq8  Dr.  white’s  Experiments 
Auguft  30th,  the  fame  quantity  of  the  air  of  my  garden, 
with  the  nitrous,  occupied  205;  after  half  an  hour  it 
was  diminifhed  to  145,  which  being  dedu&ed  gave  60, 
the  ftate  of  the  air  that  day ; and  fo  of  the  reft. 
The  medium  ftate  of  the  air  of  the  atmofphere, 
in  upwards  of  two  hundred  experiments,  was  6o°  or 
6i°. 
exp.  1.  Sept.  1 3th,  it  was  in  the  worft  ftate  I ever  ob- 
ferved  it,  58°,  the  barometer  being  30.30,  thermometer 
69°,  with  a calm,  clear  Iky,  wind  S.E.  air  dry  and  ful- 
try,  no  rain  having  fallen  for  above  a fortnight;  on  the 
fame  day  we  had  a flight  fhock  of  an  earthquake. 
exp.  11.  Sept.  20th,  much  rain  falling,  barometer 
30.00,  thermometer  6o°,  wind  being  South,  it  was  63°. 
exp.  hi.  The  next  day,  Sept.  21,  a high  wind  cleared 
the  air,  barometer  29.50,  thermometer  520,  the  air  was 
64°.  It  was  the  fame  Oft.  5,  the  wind  high  and  Wefterly. 
This  was  the  pureft  I ever  obferved. 
exp.  iv.  I have  only  obferved  it  fo  good  as  68°  in 
three  inftances,  Auguft  16,  Sept.  20, .and  29;  thefe  were 
all  fhowery  days,  with  a brifk  wind. 
exp.  v.  As  to  the  influence  of  the  different  winds 
upon  one  atmofpheric  air,  my  experiments  are  as  yet  too 
few  to  afce.rtain  it.  I have  generally  found  it  the  pureft
