characteristic  smell  of  phenol  will  be  perceived,  and  the  substance  becomes 
visible  in  the  shape  of  oily  drops. — Ibid.,  from  Rev.  hebdom.  de  Chim. 
Glycerin  as  a  Solvent  for  Aniline  Colors.— The  fact  that  glycerin  dissolves 
aniline  colors,  if  anything,  more  readily  than  alcohol,  suggests  the  idea  of  era- 
ploying  it  in  dyeing.  Experiments  affording  the  best  results  have  been  made 
on  wool,  silk  and  cotton  goods  ;  the  colors  were  found  to  adhere  with  unusual 
persistence  to  the  fibre  of  the  goods,  and  the  only  question  appears  to  be  the 
cost.  The  loss  of  glycerin  is  considerable  in  rinsing  the  cloth,  but  in  the  bath 
itself  the  same  material  can  be  frequently  used  without  detriment.  It  was 
found  that  the  brilliancy  of  color  was  decidedly  improved  by  the  addition  of 
glycerin,  especially  with  the  iodine  colors  when  a  hotter  bath  was  desirable. 
The  action  of  the  mordants  is  not  injured,  but  rather  strengthened,  by  the  ad- 
dition of  a  little  glycerin.  While  alcohol  is  considerably  evaporated  by  the 
heat,  the  glycerin  is  unaffected,  and  the  coloring  matter  is  not  precipitated. 
It  may  not  be  feasible  to  substitute  glycerin  for  alcohol  in  all  cases,  but  in  a 
majority  of  instances  it  can  be  advantageously  employed,  in  whole  or  in  part, 
on  account  of  the  better  results  obtained,  and  notwithstanding  the  additional 
cost. — Journ.  Applied  Chemistry,  August,  1872. 
Tanning  with  Glycerin. — The  property  of  glycerin  to  preserve  leather  has 
been  known  for  a  long  time  ;  it  is  now  proposed  to  employ  it  in  tanning;  to 
increase  the  elasticity  and  resistance  of  the  leather.  This  system  of  tanning  is 
particularly  adapted  to  straps  and  belts  of  machinery,  as  it  keeps  them  from 
drying  and  cracking.  It  is  only  necessary  to  immerse  the  leather,  tanned  in 
the  usual  manner,  in  a  bath  of  glycerin,  and  to  leave  it  for  several  weeks,  when 
the  pores  will  be  impregnated  with  the  greasy  substance,  and  the  leather  will 
be  found  to  be  much  more  elastic  and  tenacious. — Ibid. 
Cure  of  Hydrophobia. — Mr.  R.  C.  Shoemaker  writes  in  the  Country  Gentle- 
man, published  in  Montgomery  Co.,  Pa.,  as  follows:  The  time  between  the 
biting  of  an  animal  by  a  mad  dog  and  showing  signs  of  hydrophobia  is  not  less 
than  nine  days,  but  may  be  nine  months.  After  the  animal  has  become  rabid, 
a  bite  or  scratch  with  his  teeth  upon  a  person,  or  slobber  coming  in  contact 
with  a  sore  or  a  raw  place,  would  produce  hydrophobia  just  as  soon  as  though 
he  had  been  bitten  by  a  mad-dog.  Hydrophobia  can  be  prevented,  and  I  will 
give  what  is  well  known  to  be  an  infallible  remedy,  if  properly  administered, 
for  man  or  beast.  A  dose  for  a  man  or  cow  should  be  about  four  times  as 
great  as  for  a  person.  It  is  not  too  late  to  give  medicine  any  time  before  the 
spasms  come  on. 
The  first  dose  for  a  person  is  one  and  a  half  ounces  elecampane  root,  bruised, 
put  in  a  pint  of  new  milk,  reduced  to  one-half  by  boiling,  then  taken  all  at  one 
dose  in  the  morning,  fasting  until  after  noon,  or  at  least  a  very  light  diet  after 
several  hours  have  elapsed.  The  second  dose  the  same  as  first,  except  take 
two  ounces  of  the  root;  third  dose  the  same  as  last,  to  be  taken  every  other 
day.  Three  doses  are  all  that  is  needed,  and  there  need  be  no  fear.  This  I 
know  from  my  own  experience,  and  know  of  a  number  of  other  cases  where  it
