  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
  Cryophorus  \Cry*oph"o*rus\  (kr[-i]*[o^]f"[-o]*r[u^]s),  n.  [NL., 
  fr  Gr  kry`os  icy  cold,  frost  +  fe`rein  to  bear.]  (Chem.) 
  An  instrument  used  to  illustrate  the  freezing  of  water  by  its 
  own  evaporation.  The  ordinary  form  consists  of  two  glass 
  bulbs,  connected  by  a  tube  of  the  same  material,  and 
  containing  only  a  quantity  of  water  and  its  vapor,  devoid  of 
  air.  The  water  is  in  one  of  the  bulbs,  and  freezes  when  the 
  other  is  cooled  below  32[deg]  Fahr.
