Thiocamf. — Dr.  J.  E.  Reynolds  proposes  under  this  name  a  new 
disinfectant  prepared  by  acting  on  camphor  with  sulphur  dioxide.  At 
ordinary  temperatures  S02  requires  a  pressure  of  more  than  two  at- 
mospheres to  liquefy  it ;  but  camphor  owing  to  chemical  attraction 
can  liquefy  it  without  any  pressure  whatever.  In  the  liquid  thus 
prepared  several  known  bactericides  are  dissolved.  Thiocamf  can  be 
preserved  without  pressure  in  bottles  at  mean  temperature,  mere  ex- 
posure of  the  liquid  in  a  thin  layer  to  the  air  determines  the  steady 
evolution  of  sulphur  dioxide.  The  contents  of  a  six-ounce  bottle  will 
yield  over  20,000  cc.  S02.  One  ounce  of  Thiocamf  shaken  up  with 
a  quart  of  water  forms  a  powerful  disinfectant  for  ordinary  purposes, 
while  a  more  dilute  solution  (1  oz.  to  the  gallon)  can  be  used  for 
soaking  clothes  which  have  been  in  contact  with  infected  persons. —

Purification  of  Bisulphide  of  Carbon — In  a  paper  read  before  the 
London  Chemical  Society,  Ignatius  Singer  describes  an  improved  form 
of  furnace  and  retorts  for  the  manufacture  of  carbon  bisulphide  on  the 
large  scale.  The  crude  product  obtained  contains  considerable  quan- 
tities of  sulphur,  H2S,  and  other  sulphur  compounds,  has  a  pale 
yellow  color  and  a  very  disagreeable  odor.  The  author  recommends 
the  following  method  for  its  purification  :  A  cylindrical  vessel  about 
30  inches  in  diameter  and  6  feet  high  is  provided  with  a  perforated 
coil  of  lead  pipe  at  the  bottom.  The  CS2  to  be  purified  is  run  into 
this  vessel  to  about  one-third  its  height.  Then  lime  water  is  pumped 
into  the  vessel  through  the  perforated  coil.  The  lime  water  being 
specifically  lighter  than  the  CS2  rises  to  the  surface,  and  while  travers- 
ing the  body  of  the  bisulphide  in  a  finely  divided  spray,  the  lime  com- 
bines with  the  H2S  etc.  This  washing  is  continued  until  the  lime 
water  which  leaves  the  vessel  through  an  overflow  pipe  near  the  top, 
is  perfectly  clear.  The  CS2  is  now  run  into  a  still,  about  1  per  cent, 
of  cheap  colorless  oil  added  and  covered  with  a  layer  of  about  1  inch 
of  water  to  which  some  sugar  of  lead  may  be  added.  The  CS2  is  now 
distilled  in  a  water  bath  and  condensed  in  the  usual  way. — Jour.  Soc.

Test  to  Distinguish  Resorcin  from  Carbolic  or  Salicylic  Acid. — If  a
