neither  should  it  be  dangerously  poisonous  or  corrosive.  There  is  a 
very  common  substance  which  has  long  been  used  to  hinder  putre- 
faction. It  does  so  only  in  a  concentrated  form.  It  has  no  smell ; 
it  is  not  poisonous.  It  can  hardly  be  said  to  be  corrosive.  Its  name 
is  common  salt.  I  hold  that  this  substance  and  its  analogues — the 
chloride  of  calcium  and  the  chloride  of  magnesium — are  the  most 
available  general  disinfectants. — Pharm.  Journ.  (Lond.),  Sept.  13th,

Artificial  Ivory. — Two  pounds  of  pure  india  rubber  are  dissolved  in  thirty- 
two  pounds  of  chloroform  and  the  solution  saturated  with  purified  ammoniacal 
gas.  The  chloroform  is  then  evaporated  or  distilled  off  at  a  temperature  of 
185°  Fahr.  The  residue  is  mixed  with  pulverized  phosphate  of  calcium  or  car- 
bonate of  I'inc,  pressed  into  moulds  and  cooled.  When  the  phosphate  of  calcium 
is  used,  the  resulting  compound  partakes  in  a  great  degree  of  the  nature  and 
composition  of  genuine  ivory,  for  we  have  the  requisite  proportion  of  the  phos- 
phate, and  the  india  rubber,  which  takes  the  place  of  the  cartilage ;  and  the 
other  component  parts  of  the  genuine  article  are  of  little  importance. — Scien-
