exsiccator,  by  means  of  a  good  rubber  cork  (/),  in  the  way  shown 
(on  a  smaller  scale)  in  Fig.  j,  and  into  the  tee  the  cup-piece  before  de- 
scribed, by  means  of  a  cork  (^)  saturated  with  paraffine  and  smoothly 
bored,  after  the  lower  end  of  the  cup-piece  has  been  suitably  bent. 
The  lower  end  of  the  tee,  which  reaches  into  the  cup,  is  somewhat 
tapering,  so  that  a  small  annular  space  is  formed  around  the  inner 
tube.  The  upper  end  of  the  glass  rod  is  provided  with  some  handle, 
which  is  made  detachable,  so  that  the  glass  rod  can  be  pulled  through 
the  cork  when  the  cup-piece  needs  cleaning.    The  use  of  the  appa- 
ratus is  self-evident  :  after  it  has  been  evacuated  through  tube  hy 
the  distilling  liquid  enters  through  i,  flows  through  the  annular 
space  into  the  cup  and  through  the  hole  in  the  bottom  of  the  latter, 
and  subsequently  through  the  bent  tube  into  one  of  the  receiving 
flasks,  which  have  been  placed  in  a  circle  on  the  glass  plate  of  the 
exsiccator.  The  tee  is,  in  the  interior  of  the  latter,  on  the  side 
opposite  from  the  inlet,  suitably  provided  with  a  small  hole  (k), 
through  which  air  entering  with  the  distillate  can  escape,  so  that 
spattering  out  of  the  cup  is  avoided.    To  take  a  new  fraction,  all
