  Hygrometer  \Hy*grom"e*ter\,  n.  [Gr.  ?  wet,  moist  +  -meter:  cf 
  F.  hygrom[`e]tre.]  (Physics) 
  An  instrument  for  measuring  the  degree  of  moisture  of  the 
  atmosphere. 
 
  {Daniell's  hygrometer},  a  form  of  hygrometer  consisting  of  a 
  bent  glass  tube  terminating  in  two  bulbs,  the  one  covered 
  with  muslin,  the  other  of  black  glass,  and  containing 
  ether  and  a  thermometer.  Ether  being  poured  on  the  muslin, 
  the  black  ball,  cooled  by  the  evaporation  of  the  ether 
  within,  is  soon  covered  with  dew;  at  this  moment,  the 
  inclosed  thermometer  gives  the  dew-point,  and  this 
  compared  with  the  reading  of  one  in  the  air,  determines 
  the  humidity.
