Humidity  ol'  the  tongue,  he  tells  us,  is  a  favorable  sign,  and  that

and  more  particularly  wlien  seated  in  tlic  intestinal  canal  and  respira-
tory organs.  "This  also  happens  in  diarrhoea,  typhus,  pneumonia,
gangrene  of  the  lung,  pleuritis,  peritonitis,  enteritis,  eatarrhus  gas-
tricus,  gastritis,  inflammation  of  joints,  etc.  Among  the  higher  degrees
of  dryness  he  enumerates  the  rough,  the  fissured,  and  burnt  tongue,  a^
furnisliing  still  more  unfavorable  indications,  informing  us,  at  the  samj
time,  that  if  these  be  not  accompanied  by  thirst,  they  prognosticate  a
fatal  termination.  The  abatement  and  crisis  of  the  disease  is  indicated
by  the  tongue  becoming  moist."

Dr.  Bell,  of  Philadel[)]iia,  in  a  note  to  Prof.  Schill's  observations
on  the  tongue,  says,  "A  rough  and  dry,  and  even  furred  tongue  is  seen
in  some  dyspeptic  persons  who  sleep  with  the  mouth  open;  and  al-
though it  indicates  an  irritation  of  the  digestive  organs,  it  is  not  a  bad
augury."  Bilious  persons,  not  unfrequently,  though  not  troubled  with
any  manifest  symptoms  of  gastric  or  intestinal  derangement,  or  any
other  apparent  functional  disturbance,  have  a  furred  tongue  in  the
morning.
