apparatus  for  hypodermoclysis  or  Murphy  drip  when  not  needed 
for  wound  sterilization.  The  collapsible  stand  from  which  the 
caloris  bottle  is  suspended  can  be  quickly  attached  to  a  bed-post  of 
any  size.  The  rate  of  flow  of  the  solution  to  each  instillation  tube 
is  under  absolute  control,  being  regulated  from  the  distributing  tube 
to  the  instillation  tubes  by  means  of  individual  clamps  which  are 
attached  to  each  tube. 
By  means  of  the  glass  sight-feeds  the  attendant  or  patient  can 
see  at  a  glance  whether  the  solution  is  being  delivered  properly  to 
each  tube.  The  instillation  tubes  employed  have  rounded  ends  so 
that  they  may  be  passed  into  deeply  penetrating  or  "  through-and- 
through  "  wounds  without  great  pain  to  the  patient.  Several  wounds 
can  be  treated  from  this  apparatus  at  one  time  because  of  the 
superior  method  of  distribution.  No  support  for  the  apparatus  is 
needed  at  the  site  of  instillation,  thus  saving  the  patient  much  dis- 
comfort. 
Disadvantages  in  the  Use  of  Some  Forms  of  Apparatus 
Now  on  the  Market.2 — Before  devising  this  apparatus  no  appli- 
ance could  be  found  on  the  market  by  which  it  was  possible  to  sup- 
ply uniformly  the  solution  to  two  or  more  different  parts  of  the 
body  from  one  container.  Nor  was  there  any  satisfactory  mechan- 
ical device  available  for  attaching  the  container  of  the  solution  to 
bed-posts  of  any  size  without  building  a  framework  of  some  kind 
or  a  support  at  the  site  of  injection.  Furthermore,  none  of  the 
appliances  on  the  market  offered  a  satisfactory  method  of  controlling 
the  flow  of  solution  so  as  to  insure  uniform  distribution  to  each 
instillation  tube. 
The  two  principal  forms  of  apparatus  found  in  use  were  those 
illustrated  in  Figs.  I  and  3.  The  apparatus  shown  in  Fig.  1  is  sup- 
plied with  but  one  sight-feed  and  one  clamp  and  is  very  unreliable 
because  it  does  not  permit  uniform  distribution  of  the  solution  to 
the  instillation  tubes.  In  other  words,  when  the  solution  is  dropping 
in  the  sight-feed  at  the  usual  rate,  practically  all  of  the  solution  is 
carried  by  the  first  instillation  tube  and  very  little  ever  reaches  the 
other  three  tubes.  It  is  therefore  necessary  to  flush  the  apparatus 
at  intervals  in  order  that  some  of  the  solution  may  be  carried  by  all 
four  tubes,  and  even  then  it  is  impossible  to  obtain  an  even  distribu-
