and  formic  acids  were  detected  in  the  products.  Nitrogen  is 
not  eliminated  as  ammonia ;  but  the  author  has  not  found  any 
nitrogenised  product  in  the  liquid. 
Purified  bile,  that  is  to  say  the  mixture  of  glycocholate  and 
taurocholate  of  soda  obtained  by  evaporating  fresh  ox  bile,  treat- 
ing the  residue  by  absolute  alcohol,  and  decolorising  the  solu- 
tion by  animal  charcoal,  evaporating,  recovering  by  water,  and 
shaking  the  watery  solution  with  ether  so  long  as  it  takes  up 
anything.  Bile  thus  purified  rapidly  absorbs  large  qantities  of 
ozone.  At  whatever  stage  of  reaction  the  liquor  is  examined, 
there  will  be  found  in  it,  besides  the  undecomposed  acids,  only 
carbonic  and  sulphuric  acids.  Thi3  is  another  instance  in  which 
the  author  has  been  unable  to  decide  under  what  form  the  nitro- 
gen is  eliminated. 
Saliein.— After  a  few  days  the  liquor  becomes  acid,  when 
a  few  drops  of  alkali  are  added  the  action  of  the  ozone  contin- 
ued until  it  was  exhausted.  No  salicylic  acid  is  to  be  found  in 
the  liquid,  but  only  carbonic  acid. 
Gelatin  is  entirely  transformed  into  a  body  with  altogether 
different  properties,  not  being  in  the  form  of  jelly,  and  precipi- 
tating neither  by  tannic  acid  nor  by  bichloride  of  mercury,  but 
only  by  alum,  sulphate  of  copper,  and  mercurial  nitrate. 
Albumen,  after  the  addition  of  a  few  drops  of  potash,  be- 
haves with  respect  to  ozone  the  same  as  without  this  addition  ; 
it  furnishes  a  body  analogous  to  the  peptones. 
The  author  concludes  by  enforcing  the  analogy  which  seems 
to  him  to  exist  between  these  reactions  and  the  combustion 
taking  place  in  the  animal  organism. — Lon.  Chem.  News,  Nov.

Imperfect  as  our  researches  on  the  properties  of  the  new 
metal  and  its  compounds  must  be,  in  consequence  of  the  very 
small  amount  we  have  been  able  to  obtain,  we  think  it  advisable 
to  make  known  what  we  have  discovered,  as  we  see  no 
prospect  of  procuring  a  larger  quantity.
