Calcium  hippurate,  which  crystallizes  in  oblique  rhombic  prisms, 
and  is  soluble  in  18  parts  of  cold  water,  has  been  employed  in  uric 
diathesis,  in  scrofula  and  in  hepatic  cirrhosis ;  it  may  be  prepared 
extemporaneously,  and  for  this  purpose  is  ordered  by  Dujardin- 
Beaumetz  as  follows  :  Hippuric  acid,  1  ;  lime  water,  35,  and  syrup,

Glycerite  of  Salicylic  Acid. — M.  H.  Barnouvin  states  that  on  dis- 
solving 1  gm.  of  salicylic  acid  in  50  gm.  of  warm  glycerin,  on  cool- 
ing, the  liquid  will  remain  clear,  but  on  diluting  it  with  10  gm.  fo 
water,  a  precipitate  of  salicylic  acid  will  be  immediately  produced. 
However  a  solution  of  1  part  of  acid  in  100  parts  of  glycerin  may 
be  diluted  with  water  in  all  proportions. — Bull.  Gen.  de  Tlierap.
