\    June  1,  1872. 
many,  which  enjoy  the  greatest  circulation,  have  become  the  debating 
forum  of  the  Chloralum  Company,  so  that  it  seems  to  be  high  time 
that  an  impartial  judge,  such  as  the  Central  Chemical  Institution, 
founded,  as  it  is,  under  the  auspices  of  the  State,  should  pronounce 
unreserved  judgment  on  the  Chloralum  Industry  and  its  products. 
The  Chloralum  Company  recommends — 1.  Chloralum  as  the  safest 
disinfectant,  as  free  from  smell,  and  not  poisonous ;  and  as  adapted 
for  the  disinfection  of  urinals  and  drains,  stables,  slaughterhouses, 
street  kennels,  and  horse  dung,  for  internal  and  external  use  in  affec- 
tions of  the  throat,  diphtheria,  scarlet  fever,  small-pox,  &c. 
As  Prof.  Fleck  states  in  the  2d,  1871,  No.  4,  the  liquid  contents 
of  a  clean  labelled  vessel  weighing  637*9,  half  a  litre  in  volume,  and 
15  sgr.  (Is.  6d.)  in  price,  were  used  for  the  chemical  investigation.

2.  Chloralum  powder  is  recommended  as  an  absorbent  of  organic 
impurities,  as  an  antiseptic  and  astringent  when  combined  with 
wheaten  flour,  and  as  a  disinfectant  for  railway  carriages,  ships? 
privies,  stables,  drains,  &c. 
A  tin  canister,  also  very  handsomely  labelled,  containing  a  white 
powder  of  370  gr.  in  weight,  and  5  sgr.  (6d.)  in  price,  was  taken  to 
experiment  upon.    It  contained —
