Under  these  conditions  the  best  glass  to  furnish  is  a  glass  with 
very  large  lens  and  which  for  its  support  does  not  depend  upon  a 
bridge  but  rests  against  the  sides  of  the  nose  and  eyebrows. 
Bottle  with  Bulb  for  Flushing. 
This  consists  of  a  bulb  of  about  two  ounces  capacity  and  a  large 
wide-mouthed  bottle  of  eight  ounces  capacity  having  a  glass  cover. 
The  outfit  is  for  use  where  it  is  the  intention  to  flush  the  eye 
with  a  large  quantity  of  fluid. 
The  bulb  fits  the  bottle  in  such  a  manner  that  it  becomes  air- 
tight after  pressing  and  placing  the  end  of  the  dropper  into  the 
bottle  to  the  body  of  the  bulb  and  releasing  the  bulb. 
The  dropper  barrel  for  this  appliance  should  be  considerably 
larger  than  one  used  for  eyedrops  so  that  the  flow  will  be  much 
greater  and  with  less  force. 
Ointment  pots  or  jars  for  dispensing  eye  ointments  should  be 
composed  of  opal  glass.  There  should  be  no  metal  covering  used 
unless  protected  from  the  contents  by  paraffine  paper.  A  very  good 
jar  to  use  is  one  composed  entirely  of  glass;  or  one  where  the  base 
is  of  opal  glass  and  the  cover  celluloid. 
Glass  Applicators  are  small  devices  for  the  application  of  oint- 
ments or  semi-solid  substances  to  the  eye.  The  more  common  is  the 
plain  piece  of  glass  slightly  tapered  at  the  ends  on  which  the  medi- 
cation can  be  placed  and  transferred  to  the  eye. 
An  applicator  more  adapted  to  ointments  is  flattened  on  one 
end  and  rounded  so  as  to  remove  all  sharp  edges.

MAGNESIA.1

pital, Philadelphia. 
Ever  since  the  proprietary  preparation,  milk  of  magnesia,  has 
been  placed  on  the  market  and  become  so  popular,  attempts  have 
been  made  by  the  pharmaceutical  profession  to  develop  a  good 
working  formula  for  the  making  of  that  preparation,  but  so  far  all
