With  92  per  cent,  glycerin  and  8  per  cent,  soap  are  prepared  : 
Glycerinnm  saponatum  with  zinc  oxide  (95  :  5),  forms  a  fine  white 
mass,  permanent  in  air ;  it  is  so  firm  that  it  must  be  scraped  with  a 
spatula,  but  placed  upon  the  skin  it  softens  and  can  be  rubbed  up 
completely,  especially  in  presence  of  a  little  water.  It  is  used  for 
chapped  hands  ;  for  eczema  the  following  is  more  desirable  :  Glycer- 
inum  saponatum  78,  zinc  oxide  20,  and  starch  2. 
Glycerinnm  saponatum  with  iodoform  (95  15)  ;  much  more  iodoform 
can  be  introduced.  It  forms  a  hard  mass,  which  must  be  scraped 
with  a  spatula ;  placed  upon  sores  it  liquefies  and  penetrates  into  all 
parts  of  the  wounds.  There  is  noticeable  in  the  preparation  a 
marked  reduction  of  the  iodoform  odor. 
Also  combinations  with  sulphur,  10  per  cent.;  with  sulphur  and  zinc 
oxide,  10  and  20  per  cent,  respectively ;  with  chrysarobin,  10  per  cent.; 
with  hydroxylamine,  1  per  cent.  ;  with  ichthyol,  5  per  cent,  of  the 
ammonium  salt ;  with  ichthyol  and  zinc  oxide,  10  per  cent,  of  each  ; 
with  carbolic  acid,  generally  2  or  3  per  cent,  of  the  latter. — (Ztschr.

Ozonin,  a  bleaching  fluid,  patented  by  L.  Schreiner,  is  made  as  fol- 
lows :  125  parts  resin  are  dissolved  in  200  parts  oil  of  turpentine  ;  to 
this  solution  is  added  a  solution  of  22-5  parts  potassium  hydrate  in  40 
parts  water,  also  90  parts  hydrogen  peroxide.  The  resulting  jelly 
exposed  to  light  changes  in  2  or  3  days  into  a  thin  fluid  called  ozonin  ; 
this-  same  change  takes  place  in  the  dark,  but  then  requires  some 
weeks  for  its  completion.  An  emulsion  of  one  gram  ozonin  in  one 
liter  water  acts  as  an  energetic  bleaching  agent  on  fibres,  wood, 
straw,  cork,  paper  ;  also,  on  solutions  of  gums  and  soaps  ;  the  bleach- 
ing effect  is  as  energetic  in  acid  as  in  alkaline  solutions. —  Chemiker

Codeine  phosphate  appears  in  commerce  of  various  composition. 
By  neutralizing  codeine  with  phosphoric  acid  and  crystallizing  from 
water,  or  precipitating  the  solution  with  alcohol,  the  salt  had  the 
composition  C18H21N03H3P04  +  2H20  ;  but  if  crystallized  from  hot 
dilute  alcohol  2(C1SH21N03H3P04)  +  H20.  Both  are  found  among 
the  commercial  article. — E.  Schmidt,  Apoth.  Ztg.,  1890,  366. 
Benzosol,  the  benzoic  ether  of  guaiacol,  has  been  prepared  by  Dr. 
Bongartz  and  recommended  as  a  tasteless  substitute  for  the  locally 
irritating  guaiacol.  Taken  into  the  system  it  is  slowly  saponified 
by  the  gastric  juice  and  the  liberated  guaiacol  is  under  the  most
