from  three  to  five  drops,  the  diet  being  strictly  regulated  at  the  same 
time.  Under  this  treatment  the  sugar  disappears  rapidly  from  the 
urine ;  but  it  is  recommended  that  the  administration  of  the  remedy 
be  afterward  continued  for  several  weeks.  [Jour.  Amer.  Med.  Asso., 
May.)  Dr.  Moock  [France  Med.,  Feb.  1886),  has  used  this  arsenic 
preparation  with  success  in  similar  cases.  Notices  of  this  solution 
will  be  found  in  Amer.  Jour.  Phar.,  1883,  pp.  143  and  225. 
Salicylate  of  iron  is  given  by  Dr.  Braithwaite  [Brit.  Med.  Jour., 
July  17,  1886),  in  infantile  diarrhoea  accompanied  by  fetid  stools.  The 
solution  of  the  salt  is  prepared  extemporaneously  by  dissolving  sepa- 
rately in  water  20  grains  each  of  ferrous  sulphate  and  sodium  salicy- 
late, mixing  the  solutions,  adding  3  or  4  drachms  of  glycerin,  and 
diluting  with  water  to  3  fluidounces.  This  is  given  in  hourly  doses 
of  a  teaspoonful  until  the  stools  become  black,  when  the  same  dose  is 
repeated  every  three  or  four  hours. 
Calcium  Santonate  is  prepared,  according  to  Heldt,  by  digesting 
calcium  hydrate  with  santonin  in  alcoholic  solution,  until  the  red 
color  has  disppeared,  evaporating  the  filtrate  at  a  moderate  tempera- 
ture, exhausting  the  dry  residue  with  water  and  concentrating.  The 
salt  forms  white  satiny  crystalline  crusts,  is  permanent  in  the  air  and 
sunlight,  has  an  alkaline  taste  and  reaction,  and  is  soluble  in  water 
and  in  alcohol.  The  compound  has  recently  been  recommended  as 
possessing  anthelmintic  properties  without  being  absorbed  in  the  di^ 
gestive  tract.    The  dose  is  1  grain. 
Calcium  hippurate  is  highly  recommended  by  Poulet  in  the  uric 
acid  diathesis,  and  is  stated  to  be  useful  in  scrophulous  complaints, 
incipient  cirrhosis  of  the  liver  and  in  struma.  The  dose  is  10  grains. 
For  the  preparation  of  the  salt,  Liebig  recommended  the  aqueous  solu- 
tion of  hippuric  acid  to  be  heated  with  calcium  carbonate  ;  the  filtrate 
yields  on  concentration,  glossy  scales  or  oblique  rhombic  prisms,  which 
have  the  composition  Ca(C9H8N03)2.3H20,  are  soluble  in  18  parts  of 
cold  and  6  parts  of  boiling  water,  and  lose  at  100°  C,  the  water  of 
crystallization  amounting  to  12  per  cent. 
Dr.  Dujardin-Beaumetz  (Union  Med.,  August,  1866),  orders  the 
salt  extemporaneously  prepared  by  dissolving  1  part  of  hippuric  acid 
in  25  parts  of  lime  water  and  adding  an  equal  bulk  of  syrup ;  the 
dose  is  a  tablespoonful. 
Sal  Alembroth  or  ammonio-mer curie  chloride  is  now  largely  used  by 
Sir  Joseph  Lister  for  dressings,  the  solution  used  for  rendering  ban-
