Peepaeations  of  Sozoiodol. — A  5  to  10  per  cent,  solution  re- 
tards the  development  of  pyogenous  cocci ;  10  per  cent,  solutions  pre- 
vent the  development  of  microbes  ;  20  per  cent,  solutions  render  gel- 
atin sterile.  In  doses  of  1  gm.  sozoiodol  is  not  toxic  to  rabbits.  For 
open  wounds,  2  or  3  per  cent,  solutions  of  the  acid  (diiodoparaphenol- 
sulphonic)  with  the  salts  of  sodium  or  aluminium  is  used.  For  a 
prolonged  action  the  sozoiodol  of  potassium  is  mixed  dry  with  pow- 
dered talc  or  milk  sugar  in  quantities  of  5  to  10  per  cent.  For  oint- 
ments, sozoiodol  of  potassium,  sodium,  aluminium  or  lead  may  be 
used  in  the  proportions  of  5  to  10  percent.,  with  lanolin.  For  insuf- 
flations, the  sotlic  or  potassic  salt  is  mixed  with  sugar  of  milk.  The 
same  is  true  of  the  zinc  salt  which  may  contain  1  to  10  per  cent. ;  and 
the  mercury  salt,  which  should  be  made  with  5  to  10  of  the  latter 
to  90  or  95  of  sugar  of  milk. — Nouv.  Rem.,  Nov.  24. 
Unna's  Topical  Applications  in  Skin  Diseases. — Dr.  Hallo- 
peau  in  a  recent  visit  to  Unna,  learned  that  he  has  been  engaged  in 
perfecting  these  applications,  which  are  recommended  in  three  forms : 
medicated  paste  ;  ointments  spread  upon  muslin,  and  plasters  similarly 
prepared.  The  paste,  used  as  a  vehicle,  prolongs  the  action  of  the 
medicaments,  retains  the  secreted  water  upon  the  surface  of  the  skin, 
augments  cutaneous  respiration  and  quiets  irritation.  The  applica- 
tions are  intended  for  prolonged  use  without  re-dressing.  The  soft 
paste  of  Unna  is  made  as  follows:  Oxide  of  zinc,  15  ;  glycerin,  15; 
gelatin,  25  ;  water,  25.  The  muslin  plasters  are  prepared  by  making 
the  fabric  impermeable  with  caoutchouc  dissolved  in  benzol  or  the 
oleate  of  aluminium.  M.  Vigier  in  recent  experiments  on  the  prep- 
aration of  the  plasters  gives  the  preference  to  a  coating  of  soft  paraffin 
mixed  with  gutta-percha  dissolved  in  bisulphide  of  carbon.  Unna's 
paste,  spread  on  these  plasters,  or  used  as  an  ointment,  is  said  to  "  ren- 
der great  service  in  the  treatment  of  pruritus,  eczema,  intertrigo  and 
acne." — R.  Blondel,  J.  de  Ph.  et  de  Ch.y  Dec.  1. 
Veemillonette. — In  an  aqueous  solution  of  eosine,  minium  is 
placed  in  suspension  and  briskly  agitated,  while  adding  a  solution  of 
acetate  or  nitrate  of  lead  until  the  color  is  wholly  precipitated.  Wash, 
press  and  bolt.    The  color  is  very  brilliant,  but,  like  all  eosine  colors,
