as  cement,  which  dries  quick  and  is  insokible  in  water. — Ibid,  from 
ibid. 
Excellent  Polishing  Powder  for  Metals. — Magnesia  40  parts,  carbo- 
nate of  calcium  40  parts,  red  oxide  of  iron  7  parts. — Chevalier,  in 
ibid. 
Cement  for  Tubes  of  Glass  and.  Copper. — Mix  very  finely  powdered 
gypsum  with  oil  until  the  mass  becomes  somewhat  hard  ;  then  for 
every  50  parts  of  oil  incorporate  100  parts  of  all)nmen  by  trituration 
in  a  mortar.  This  cement  must  be  used  at  once,  since  it  hardens  rap- 
idly.— Ibid,  from  ibid. 
A  permanently  elastic  solution  of  acacia  is,  according  to  Wien.  ilL 
Gew.  Ztg.,^^  obtained  in  the  following  way :  Dissolve  93  parts  of 
acacia  in  sufficient  water  to  obtain  a  liquid  of  syrupy  consistency. 
Dissolve  1  part  of  salicylic  acid  in  '10  parts  of  alcohol ;  add  3  parts 
of  glycerin  and,  lastly,  3  parts  of  green  soap,  and  mix.  This  solution 
keeps  well,  and  besides  being  very  elastic  possesses  considerable  adhe- 
siveness.— Erfind  u.  Erfahr.,  No.  9,  1885. 
Antidiabetic  Clioeoiate. — Glycerin,  500  grams,  is  to  be  reduced,  at 
a  low  temperature,  to  300  grams;  then  melt  1,000  grams  of  Caracas 
cacao,  freed  from  oil,  and  stir  with  the  glycerin  until  incorporated. 
Salts,  aromatics,  sugar,  etc.,  may  be  added  if  ordered  by  the  physician.

In  place  of  reducing  the  glycerin  by  evaporation,  use  only  300 
grams  of  concentrated  glycerin,  thus  avoiding  the  loss  of  200  grams  of 
glycerin. 
Remedy  for  ErecMes. — Halkin  (''Ann.  Soc.  de  Liege recommends 
to  proceed  as  follows :  Wash  the  skin  well  and  dry ;  then  paint  the 
spots  by  means  of  a  brush  which  has  been  slightly  dipped  in  melted 
carbolic  acid,  at  the  same  time  stretching  the  skin  by  means  of  the  fin- 
gers. Let  dry  without  washing  or  removing  the  forming  skin,  which 
after  some  time  assumes  the  natural  color. — Ph.  Centralhalle^  1885,  p. 
344. 
Oxalic  Ether. — Richardson  ("Asclepiad  ")  recommends  this  cotDpound 
for  hypodermic  injection.  It  is  obtained  by  digesting  absolute  alcohol  and 
oxalic  acid  at  a  moderate  temperature,  and  is  a  colorless  liquid  of  an  agree- 
able odor.  Unlike  sulphuric  ether,  it  does  not  cause  pain  when  injected 
under  the  skin,  and  the  resultiujjj  inflammation  is  sli<>ht.  It  is  suggested 
as  a  useful  application  to  morbid  growths,  either  externally  or  by  deep  in>- 
jections.— iV.  Y.  Med.  Jour.^  .lune  20,  1885.
