ON  HYPOPHOSPHITE  OF  LIME. 
The  preparation  is  of  a  deep  red  color,  with  an  intensely 
acrid  taste.  Each  fluid  drachm  represents  thirty  grains  of  the 
root.

ON  A  CONTKIVANCE  FOR  DISPENSING  OILS. 
To  the  Editor  of  the  Journal  of  Pharmacy : 
Sir  : — If  you  think  the  following  worth  an  insertion  you  can 
make  use  of  it. 
The  constant  annoyance  occasioned  by  the  necessity  of  al- 
most hourly  cleansing  the  shop  bottles  from  which  castor  oil, 
&c,  are  dispensed,  led  me  to  design  the  following  simple  method 
of  obviating  the  difficulty.  Select  a  tincture  bottle  with  a  wide 
lip,  slightly  elevated  on  its  external  circumference ;  in  the  mouth 
of  this  fit,  by  grinding,  a  piece  of  thick  glass  tube  about  two 
inches  long ;  when  fitted,  file  off  slightly  one  side  of  the  convex 
surface  of  that  part  of  the  tube  fitted  into  the  neck,  and  fasten 
the  tube  with  any  kind  of  cement  insoluble  in  the  contents  of 
the  bottle.  The  drop  of  oil  or  other  liquid  left  after  each  pour- 
ing falls  on  the  lip,  and  passes  back  into  the  bottle.  I  have 
fitted  my  own  castor  oil  and  hair  oil  bottles,  and  molasses  jug 
of  the  family,  on  this  plan,  and  they  have  not  required  cleaning 
since,  from  the  soiling  of  the  contents.  I  use  the  necks  of  olive 
oil  bottles  for  tubes,  and  collodion  for  cement.  They  do  not 
require  flattening,  as  the  imperfection  of  the  circle  leaves  sufficient 
room  for  the  oil  to  pass.  This  is  a  trifling  matter ;  but  if  druggists 
would  communicate  such  simple  devices  to  each  other,  we  should 
soon  acquire  a  stock  sufficient  to  form  an  addendum  to  Faraday's 
Manipulations,

By  E.  Scheffer. 
When  the  hypophosphites  first  came  in  use,  I  followed  the 
usual  method,  to  make  hypophosphite  of  lime,  by  boiling  the 
phosphorus  with  lime.    Every  one  who  has  made  this  prepara-
