(lito  2  dr.),  and  applied  it  to  the  whole  body,
excepting  the  head,  in  a  similar  way  to  the
sulphur  bath,  and  continued  the  application

Fnmigation,  If i'trons.  Syn.  Fttmigatio  Ni-
TEOSA.  Prep.  (P.  Cod.)  Sulphuric  acid,  di-
luted with  half  its  weight  of  water,  is  placed
in  a  porcelain  cup  (any  shallow  vessel  of  glass
or  earthenware  will  do),  placed  over  heated
cinders,  and  small  quantities  of  powdered  nitre
added  to  it  from  time  to  time.
Obs.  Heat  causes  the  gas  to  be  evolved
more  rapidly,  and  thus  renders  the  fumes  more
offensive,  without  increasing  their  efficacy.
