140  Dr.  haygarth's  Obfervations  on  the 
therefore,  be  wonderful  that  difeafes  fliould  be  produced 
where  fuch  poifon  is  infpired  with  every  breath.  This 
noxious  air  is  the  moft  frequent  caufe  of  malignant  fe- 
vers. In  thefe  poor  habitations,  when  one  perfon  is 
feized  with  a fever,  others  of  the  family  are  generally 
affeCted  with  the  fame  fever  in  a greater  or  lefs  degree. 
This  dreadful  confequence  is  naturally  to  be  expeCted, 
as  putrid  fteams  arifing  from  the  difeafed  body  are  added 
to  the  other  increafing  caufes  that  produce  noxious  air. 
If  a regulation  could  be  univerfally  adopted  of  imme-

moft  falutary  confequences  would  follow.  Reafonable 
objections  might  be  made  to  receiving  fuch  patients  into 
the  general  infirmary,  even  into  feparate  wards,,  left  the 
infection  fliould  fpread  through  the  whole  houfe,  which 
in  a former  paper  on  this  fubjeCt  was  proved  to  be 
healthy  to  an  uncommon  degree  when  compared  with 
other  hofpitals.  But  might  not  this  and  every  other 
objection  be  obviated  by  erecting,  on  the  ground 
which  adjoins  and  belongs  to  the  infirmary,  a building, 
to  be  divided  into  fpacious,  airy,  feparate  apartments,, 
where  patients  infeCted  with  fevers,  and  properly  recom- 
mended,might  be  received  on  any  day  of  the  week?  Be-
