oxide.  The  solution  should  be  promptly,  evaporated  in  the  dark 
chamber.  Fluoride  of  silver  reacts  upon  the  chlorides  of  the 
metalloids  by  replacing  their  chlorine  with  fluorine.  The  chlorides 
of  phosphorus,  silicium  and  boron  are  thus  transformed  into 
fluorides.  The  same  action  is  produced  with  the  organic  com- 
pounds of  chlorine,  iodine  or  bromine.  Fluoride  of  silver  fuses  at 
435°  C. 
Solutions  of  Boric  Acid  and  Corrosive  Sublimate. — M.  Rous- 
seau (Soc.  de  Phar.,  March  10)  had  occasion  to  prepare  a  solution 
of  the  above  in  alcohol  and  water,  using  crystallized  boric  acid. 
He  observed  a  deposit  of  red  oxychloride  of  mercury  which  passed 
to  a  deep  brown.  On  using  boric  acid  in  scales,  no  precipitate  was 
given.  He  found  that  the  crystallized  acid  contained  traces  of 
borate  of  sodium. 
Ethereal  Pulverizations  of  Corrosive  Sublimate.  —  The 
formula,  as  used  by  Dr.  Talamon  in  the  treatment  of  erysipelas  and 
variolic  pustulae,  is  as  follows:  Corrosive  sublimate,  and  citric  or 
tartaric  acid,  aa  1  gm.;  alcohol  of  90%,  5  ccm.;  sulphuric  ether,  q.  s. 
to  make  100  ccm.  One  application  frequently  arrests  the  progress 
of  erysipelas.  After  the  temperature  has  gone  down,  two  or  three 
pulverizations  may  be  made  daily  to  insure  a  cure. 
Vinous  Lemonades. — The  editor  of  the  Repert  de  Phar.  (April 
10,)  writes  as  follows  :  Some  physicians  prescribe  vinous  lemon- 
ade, and  Dr.  Dujardin-Beaumetz  has  lately  recommended  it  in 
the  treatment  of  typhoid  fever,  to  promote  diuresis.  There  is  no 
formula  in  the  Codex  for  this  preparation.  I  give  below  some  of  the 
formulas  in  use:  Formula  of  the  Paris  Hospitals:  Red  wine,  250 
gm. ;  tartric  syrup, 1  60  gm. ;  water,  700  gm.  Formula  of  the  Marine 
Hospitals'.  Tartric  lemonade,  900  gm. ;  red  wine,  100  gm.  Fofmula 
of  MM.  Dujardin-Beaumetz  and  Yvon :  Citric  lemonade,  750 
gm. ;  red  wine,  250  gm.  Dr.  Deschamp  prefers  white  wines  for 
this  purpose.  M.  Lailler,  pharmacist,  proposes  the  following:  Citric 
syrup,  60  gm.;  red  Bordeaux  wine,  250  gm. ;  essence  of  lemon,  1 
gm.  ;  water,  700  gm.  It  seems  to  us  that  the  quantity  of  syrup 
above  indicated  is  insufficient,  also  that  tincture  of  lemon-peel 
should  be  used  instead  of  the  essence  of  lemon.    So  we  propose  the 
1  Tartric  syrup  contains  1  per  cent,  of  tartaric  acid  ;  and  tartric  lemonade  is 
made  by  mixing  tartric  syrup,  100  gm.,  with  distilled  water,  900  gm.  — Editor.
