•In  cases  of  delayed  resolution,  in  some  the  leucocytes  reached  normal  htion
the  temperature ;  in  others  both  temperature  and  leucocytes  were  normal  before
resolution  was  complete ;  again,  in  others  the  temperature  was  normal  before  the
leucocytes.
The  cases  of  terminal  pneumonia  vary  much,  our  series  showing  two  vith
counts  above  50,000  and  two  below  3500.  Alcoholics  had  almost  no  lencocytosis.
and  yet  some  recovered.  In  all  cases  followed  by  empyema  tbe  leucocytes  for  the
most  part  showed  no  change  which  would  indicate  when  the  resolution  or  ttie
empyema  began.  In  one  case  throughout  the  whole  disease  and  to  the  lime  of
the  operation  there  was  no  leucocytosis,  and  in  another  case  the  leucocytes  did
not  rise  at  all  until  the  empyema  began.  In  2  cases  followed  by  pleurisy  with  effu-
sion the  leucocytes  were  normal  after  the  crisis  (6000  and  8000).  In  3  fatal  am
ending  in  abscess  of  the  lung  the  leucocytes  were  respectively  46,000,  30,000,  ind
8500.  In  35  cases  with  various  pus  infections,  endocarditis,  pericarditis,  meningitis,
parotitis,  otitis  media,  phlebitis,  thrombosis,  tonsillitis,  etc.,  very  little  could  be
learned  from  the  leucocytes ;  that  is,  there  was  no  notable  rise,  although  the  fail
may  have  been  delayed.     If  already  low,  they  did  not  rise.
