Melt  in  a  dish  set  in  boiling  water  for  half  an  hour.  Apply  with  a 
metal  spray  to  form  a  thick  layer  on  the  affected  surface.  Next 
cover  with  a  very  thin  layer  of  cotton,  while  the  wax  is  still  hot,  and 
then  with  a  earner s-hair  brush  paint  on  three  or  four  layers  of  the 
wax.   After  it  has  hardened  for  ten  minutes  bandage. 
For  Vermin  in  the  Trenches. — A  mixture  of  equal  parts  of 
oil  of  peppermint  and  oil  of  eucalyptus  is  stated  to  answer  splen- 
didly for  lice.  A  little  is  smeared  on  the  body  with  the  fingers,

Mange,  Rigworm,  and  Lice  in  Horses. — In  an  article  describ- 
ing the  conditions  under  which  horses  may  become  affected  with 
skin  disease,  a  very  full  account  of  the  methods  of  treatment  for 
mange,  ringworm,  and  lice  is  given.  For  mange  it  has  been  found 
that  a  mixture  of  sulphur,  4  oz. ;  oil  of  tar,  1  oz. ;  sperm  oil,  1  quart, 
gives  the  best  results.  Before  applying  this  a  cleansing  agent  should 
be  used,  and  for  this  purpose,  paraffin  emulsion  is  the  best  thing  to 
use.  When  the  washed  surface  is  dry  the  sulphur  mixture  is  ap- 
plied with  a  brush,  and  well  brushed  in.  The  application  is  not  dis- 
turbed for  six  days,  when  it  should  be  removed  by  washing.  For 
ringworm,  tincture  of  iodine  has  been  mostly  used,  and  with  good 
results.  Two  applications  are  usually  sufficient.  If  the  lesions  are 
scattered  and  widespread,  the  oily  dressing  used  for  mange  gives 
the  best  results,  one  application  well  applied  generally  being  suffi- 
cient. For  lice,  after  clipping,  as  in  the  other  cases,  trie  thorough 
application  of  liquor  cresolis  and  water,  1  in  40,  gives  very  good  re- 
sults. (The  cresol  preparation  is  not  specified,  but  probably  liq. 
cresolis  saponatus  would  answer,  or  simply  a  solution  of  soft  soap 
in  an  equal  weight  of  cresol.)  Paraffin  emulsion  also  is  excellent, 
and  it  thoroughly  cleanses  the  skin  at  the  same  time.  Stavesacre 
solutions  are  most  satisfactory.  (Capt.  J.  F.  D.  Tutt,  A.V.C.,  Vet.

Synthetic  Rubber  from  Carbide. — The  manufacture  of  ace-
