Loretin  or  m-Jodo-o-oxychinoline-ana-sulphonic  acid  a  substitute 
for  iodoform  and  carbolic  acid,  forms  a  yellow  crystalline  powder 
which  is  difficultly  soluble  in  water  and  alcohol  and  insoluble  in 
ether  oils ;  suspended  in  collodion  and  oils  it  is  useful  for  certain 
purposes  ;  mixed  with  a  few  per  cent,  of  magnesia  it  can  be  used  as 
a  dusting  powder.  With  the  alkalies  it  forms  orange  red  salts 
soluble  in  water,  a  2-5  per  cent,  solution  of  the  sodium  salt  can 
replace  carbolic  acid  water  as  a  wash.  The  calcium  salt  is  insoluble 
and  can  be  precipitated  upon  gauze  by  first  impregnating  the  gauze 
with  the  sodium  salt  and  then  immersing  in  solution  of  calcium 
chloride. — Pharm.  Ztg.,  1893,  746. 
Gymnemic  acid  is  recommended  by  Dr.  V.  Oefele  as  a  means  of 
counteracting  the  disagreeable  sweet  or  bitter  taste  so  noticeable  in 
cases  of  diabetes.  As  a  convenient  mode  of  administering  the  acid 
OT  gm.  is  dissolved  in  sufficient  alcohol  so  as  to  impregnate  4  gms.

Benzoylcinchonine  is  prepared  by  E.  Leger  by  the  following  pro- 
cess which  is  a  modification  of  Schiitzenberger's  process,  published 
in  1858  :  50  gm.  of  precipitated  and  dried  cinchonine  are  introduced 
into  a  vial  with  30  gm.  benzoyl  chloride ;  close  the  vial  and  heat  on 
a  water-bath  for  an  hour,  when  the  reaction  is  finished,  take  up  the 
viscous  product  with  water  ;  add  to  this  solution  an  excess  of  N  H3 
and  agitate  with  ether.  The  ethereal  solution  is  washed  with  water, 
concentrated  by  distillation,  and  allowed  to  rest  for  a  day.  Now 
decant  the  ethereal  solution  of  benzoylcinchonine,  evaporate,  and 
place  the  viscous  product  under  a  bell-glass  over  sulphuric  acid. 
When  it  has  completely  solidified,  pulverize  it,  redissolve  .in  ether, 
filter  and  concentrate  the  solution  when,  after  twenty-four  hours,  the 
benzoylcinchonine  will  crystallize  out.  It  is  insoluble  in  water, 
but  forms  syrupy  solutions  with  alcohol  and  ether,  from  which  it  does 
not  again  crystallize ;  it  is  much  less  soluble  in  absolute  ether.  It
