wounds,  unirritating  to  the  most  sensitive  skin,  highly  retentive  of 
the  acid,  and  almost  destitute  of  odor.  It  should,  when  used,  be 
folded  in  about  8  layers.  It  loses  the  paraffin  and  resin  when  washed 
in  boiling  water,  so  the  same  gauze  may  be  used  repeatedly. — Lister. 
24.  Protective  against  Local  Irritatifig  Effects  of  Carholic  Acid  in 
Antiseptic  Dressings.. — Varnish  oiled  silk  on  both  surfaces  with  copal 
varnish.  When  dry,  brush  over  with  a  mixture  of  starch  and  dex- 
trin, to  give  it  a  film  of  material  soluble  in  water,  so  that  it  becomes 
uniformly  moistened  when  dipped  into  antiseptic  lotion.  When  not 
at  hand,  common  oiled  silk  may  be  used  as  a  substitute  for  it,  if 
smeared  with  an  oily  solution  of  carbolic  acid,  and  used  in  two  layers, 
to  make  up  for  its  inferior  efficiency. — Lister. 
25.  Antiseptic  Adhesive  Plaster. — Dip  ordinary  strapping  in  hot 
solution  of  carbolic  add,  made  by  mixing  1  part  of  1  to  20  lotion 
with  2  parts  of  boiling  water.  Will  adhere  to  a  moist  skin,  so  that 
it  may  be  employed  under  spray  when  advisable. — Lister.

liquid,  once  a  day,  over  the  diseased  parts,  by  means  of  a  brush. 
For  scabies,  sponge  all  the  parts.  The  clothes,  &c.,  of  the  affected 
individual  should  also  be  treated  with  the  liquid. — Lemaire.
