fymptoms.  Healthy  perfons,  admitted  for  the  cure  of 
recent  wounds  and  other  accidents,  foon  become  pale, 
lofe  their  appetite,  and  are  generally  difcharged  weak 
and  emaciated,  but  foon  recover  by  the  benefit  of  frefh 
air.  In  fome  hofpitals  the  cure  of  a compound  fradture 
is  rarely  feen;  in  private  practice,  and  a pure  air,  fuch 
cafes  feldom  fail.  Such  and  many  more  are  the  effects 
of  bad  air,  which,  though  not  virulent  enough  to  caufe 
a putrid  fever  in  its  more  malignant  form,  is  yet  fuffi-- 
cient  to  excite  it  to  fuch  a degree  as  to  undermine  the 
conftitutions  of  the  patients,  and  render  the  diforders,  for 
which  they  were  admitted,  anomalous,  tedious,  and J 
fatal. 
We  have  demonftrated,  that  the  effluvia  of  vegeta- 
bles, even  whilft  perfectly  fweet  and  frefh,  are  equally 
poifonous  with  thofe  from  animal  fubftances . The  vege- 
tables were  feparated  from  their  parent  plant,  confe- 
quently  not  in  a growing  or  vegetating  ftate. 
exp.  xiv.  Being  defirous  of  finding  the  effects  of 
effluvia  from  ripe  fruit  upon  air,  fix  ripe  goofeberries 
fliced  were  inclofed  fixteen  hours  in  a phial  with  eight 
ounces  of  common  air : the  air  being  then  put  to  the  teft, , 
was  found  to  be  diminifhed  from  62°  to  40°. 
Hence.
