has  been  entirely  successful.  This  is  no  guess-work.  Those  persons  I  allude 
to  were  bitten  by  their  own  dogs,  that  had  been  bitten  by  rabid  dogs,  and  were 
penned  up  to  see  if  they  would  go  mad  ;  they  d.d  go  mad,  and  did  bite  the  per- 
sons. This  remedy  has  been  used  in  and  about  Philadelphia  for  forty  years 
and  longer  with  great  success,  and  is  known  as  the  Goodman  remedy.  I  am 
acquainted  with  a  physician  who  told  me  he  knew  of  its  use  for  more  than  thirty 
years,  but  never  knew  a  case  that  failed  where  it  was  properly  administered. 
Among  other  cases  he  mentioned  was  one  where  a  number  of  cows  had  been 
bitten  by  a  mad  dog.  To  half  of  the  number  they  administered  this  remedy,  to 
the  other  half  not.  The  latter  all  died  with  hydrophobia,  while  those  who  took 
the  elecampane  and  milk  showed  no  signs  of  that  disease. 
Use  of  the  Essence  of  Eucalyptus  Globulus  to  disguise  the  Odor  and  Taste  of 
Cod-liver  Oil. — The  researches  of  Prof.  Gubler  on. the  Eucalyptus  Globulus 
and  its  essence — Eucalyptol— has  suggested  to  M.  H.  Duquesnel  a  trial  of 
the  effect  of  the  Eucalyptol  in  masking  the  disagreeable  flavor  and  odor  of  cod- 
liver  oil,  and  the  result,  he  says,  has  been  most  satisfactory.  He  mixes  one 
hundred  parts  of  cod-liver  oil  with  one  part  of  the  essence  of  eucalyptus.  The 
oil  thus  aromatized,  he  states,  has  neither  the  taste  nor  odor  of  cod-liver  oil ; 
it  is  readily  swallowed  and  leaves  in  the  mouth  or  on  the  tongue  only  the  flavor 
of  the  essence  with  which  it  is  mixed  :  and  the  disagreeable  eructations  which 
follow  the  taking  of  the  pure  oil  are  completely  modified.  The  aromatic  oil  may 
be  kept  for  a  long  time  if  the  bottle  in  which  it  is  placed  be  maintained  very 
closely  stoppered. — Med.  News  and  Library,  August,  1872, from  Rev.  de  The-

Oxidation  of  Sulphur  by  Ozone. — Prof.  A.  W.  Wright*  has  made  the  obser- 
vation, in  using  the  Holtz  Electrical  Machine,  that  the  ebonite  insulators  gene- 
rally employed  in  this  form  of  machine,  frequently  become  covered  in  warm 
weather  with  a  moisture  possessing  an  acid  taste  and  reaction,  and  which  proved 
upon  examination  to  contain  sulphuric  acid.  The  difficulty  of  using  the  ma- 
chine at  times  must  now  be  ascribed  partly  to  the  presence  of  this  substance, 
which  exalts  very  considerably  the  electrical  conductivity  of  the  hygroscopic 
moisture  always  present  on  the  insulators.  Further  examination  proved  that 
the  acid  originated  from  the  action  of  the  ozone  on  the  ebonite  insulators^ 
slowly  attacking  them  and  oxidizing  the  liberated  sulphur.  Experiments  made 
with  a  view  to  determine  whether  sulphur  could  be  directly  oxidized  by  ozone 
were  unsuccessful. — Journ.  Frank.  Inst.,  Aug.,  1872. 
The  Use  of  Sulphuretted  Hydrogen  as  a  Blow-pipe  Reagent. — Mr.  J.  Lan- 
dauer  has  communicated  to  the  Chemical  Society  of  Berlin  the  fact  that  it  is 
perfectly  feasible  to  obtain  all  the  characteristic  sulphide  precipitations  usually 
obtained  in  the  wet  way,  by  simply  mixing  the  metallic  compound  to  be  tested 
with  powdered  hyposulphite  of  soda,  and  bringing  the  same  upon  a  borax  bead
