LAND'S  IMPROVED  ATMOSPHERIC  WASHING  BOTTLE. 
We  present  a  cut  of 
an  improved  form  of 
*  Washing  Bottle,'  for 
the  use  of  analytical 
chemists.  It  may  be 
described  as  follows : 
A  flat  bottom  Bohe- 
mian flask,  A  (of  about 
one  litre  capacity),  has 
a  branch  opening,  D, 
on  its  neck,  as  repre- 
sented; into  the  mouth 
of  this  opening  is  in- 
serted a  caoutchouc 
stopper,  E,  through 
which  a  piece  of  strong 
glass  tube  projects 
(for  one  inch),  at  its 
outer  end ;  over  this 
tube  the  india-rubber 
syringe   bulb,    C,  is 
slipped,  and  secured  by  binding  with  wire  or  twine. 
The  glass  tube  or  'jet  tube,'  F,  passes  in  the  usual  manner  through 
the  larger  india-rubber  stopper,  B,  and  extends  nearly  to  the  bottom 
of  the  vessel.  When  using  the  bottle  it  is  supported  by  placing  the 
middle  or  second  joint  of  the  index  finger  under  the*  lateral  tube  at 
E  while  kthe  bulb,  C,  comes  into  the  palm  of  the  hand,  and  may  be 
pressed  to  the  desired  extent,  forcing  a  fine  stream  of  the  distilled 
water  from  F  with  any  required  force.  Upon  relieving  the  bulb  of 
the  pressure,  it  takes  air  through  the  tube  F  very  quickly. 
This  improved  bottle  obviates  the  inconvenience  of  blowing  with  the 
mouth  (which  often  contaminates  the  water),  and  it  furnishes  a  fine 
stream  of  water,  perfectly  under  the  control  of  the  operator.  Its 
convenience  and  cleanliness  must  yet  be  universally  acknowledged. 
This  form  of  bottle  was  devised  by  Wm.  J.  Land,  analytical  chemist, 
Atlanta,  Ga.,  more  than  five  years  ago ;  he  has  had  several  of  these 
bottles  in  constant  use  ever  since,  and  makes  known  its  merits  at  the
