SOLUBILITY  OF  PARAFFINE.  471 
the  pleasantly  tonic  virtues  of  sulphur  fumigations  may  be 
learned  from  a  statement  in  the  most  recent  work  on  Materia 
Medica,  Dr.  Scoresby-Jackson's  "  Note-Book,"  where  he  states 
that  in  sulphur  fumigations  66  great  care  must  be  taken  to  protect 
the  respiratory  organs  from  the  fumes  by  closing  the  apparatus 
round  the  neck ;"  and  yet  how  inconsistent  these  ordinary  views 
are  with  popular  experience  may  be  learned  from  the  popular 
idea  of  the  great  benefit  to  be  derived  from  new  flannel,  that  is, 
flannel  thoroughly  impregnated  with  sulphur  fumes,  and  also  with 
the  fact  that  in  woollen  mills,  in  certain  departments  of  them, 
the  workmen  live  from  year's  end  to  year's  end  in  an  atmosphere 
thoroughly  impregnated  with  sulphurous  acid  gas.  Unquestion- 
ably a  laborious  and  tedious  accumulation  of  experience  in  regard 
to  the  positive  influence  of  sulphur  fumes  upon  the  health  may 
be  anticipated  by  an  inquiry  into  the  ordinary  condition  of  such 
workmen ;  and  we  shall  feel  obliged  if  any  of  our  readers  shall 
be  kind  enough  to  contribute  any  information  on  this  head,  simi- 
lar to  that  which  was  contributed  to  the  "  Monthly  Journal,"  by 
Dr.  Thomson,  of  Perth,  in  regard  to  the  influence  of  an  atmos- 
phere charged  with  oil.    It  would  indeed  prove  singular  if,  after 
all,  the  benefit  supposed  to  be  derived  from  oil  was  solely  due  to 
sulphur. — Lond.  JPharm.  Journ.j  August,  1866,-  from  London

SOLUBILITY  OF  PARAFFINE. 
August  Yogel  has  determined  the  solubility  of  parafiine  in 
benzole,  chloroform  and  sulphide  of  carbon.  The  parafiine  ex- 
perimented with  melted  at  48°  C,  and  congealed  at  45°.  The 
benzole  had  the  specific  gravity  0*887.  One  part  of  the  benzole 
at  46°  C.  dissolved  7*7  parts  of  parafiine  ;  at  43°  5-0  do. ;  at  39° 
4-0  do.  ;  at  23°  0-7  do. ;  at  20°  0-3  do. 
Solubility  in  Chloroform. — One  part  of  chloroform  at  23°  dis- 
solved 0-22  parts  parafiine.  One  part  of  chloroform  at  20°  dis- 
solved 0*16  parts  parafiine. 
Solubility  in  Sulphide  of  Carbon. — One  part  of  sulphide  of 
carbon  at  23°  dissolved  an  equal  weight  of  parafiine. 
Comparative  experiments  with  stearic  acid  showed  that  one
