tures.  It  is  said  to  have  the  same  food  value  as  gelatine,  and  may 
be  used  in  connection  with  thirst-quenching  drinks.  (Pilar.  Central- 
halle.) 
Gly conic  acid. — An  oxidation  product  of  cane  sugar,  described  as 
being  a  thick  syrupy  liquid  that  does  not  reduce  Fehling's  solution ; 
has  been  suggested  as  an  available  food  in  cases  of  diabetes.  (Apothek. 
Zcit.) 
Glycosal. — Monosalicylic  acid  glycerin  ester  ;  a  white  crystalline 
powder  melting  at  about  760  C.  Slightly  soluble  in  cold  water, 
more  freely  soluble  in  hot  water  or  alcohol,  but  not  readily  dis- 
solved by  ether  or  chloroform.  Miscible  with  glycerin,  and  readily 
saponified  by  alkalies  or  the  alkaline  carbonates. 
Said  to  possess  the  antiseptic  and  antirheumatic  properties  of 
salicylic  acid,  and  may  be  used  in  place  of  any  of  the  salicylates  to 
advantage.    (Fharm.  Zeit.t  1902.) 
Ichthyol. — Sulphoichthyolate  of  iron,  and  sulphoichthyolate  of 
calcium  are  being  recommended  for  internal  use  in  prefereace  to  the 
more  soluble  salts  of  ammonium  or  sodium,  the  former  having  the 
advantage  of  being  odorless  and  tasteless. 
Ferrichthyol. — The  name  given  to  sulphoichthyolate  of  iron  ;  is  to 
be  given  in  doses  of  1 -oo  or  2-00. 
Several  substitutes  for  ichthyol  have  appeared  recently  ;  one  of 
these,  ichtainmon,  being  put  on  the  market  by  F.  Reichert,  Breslau, 
is  said  to  be  obtained  by  destructive  distillation  from  a  bituminous 
shale  formation.  This  distillate,  subsequently  neutralized  with  NH3, 
gives  a  substance  closely  resembling  ichthyol  in  physical  properties, 
and  its  therapeutic  value  is  said  to  be  the  equal  of  ichthyol  in  every 
way.    [Pharm.  Zeit.y  1902). 
Thigenol. — A  sulphonate  of  soda,  said  to  contain  10  per  cent,  of 
sulphur  ;  is  freely  soluble  in  water  and  diluted  alcohol ;  has  a  slightly 
alkaline  reaction.  This  compound  has  also  been  recommended  as  a 
substitute  for  ichthyol,  and  is  said  to  be  preferable  on  account  of 
the  absence  of  the  disagreeable  odor  of  the  latter.  (Apoth.  Zeit., 
1902). 
Phenolphtalein. — Also  known  or  sold  as  purgo,  is  again  mentioned 
as  an  efficient  and  reliable  purgative,  given  in  doses  of  010  to  0-50. 
Solvo sal-lithium. — Lithium  salolo  phosphoricum  is  a  powder  solu- 
ble in  20  parts  of  water,  and  recommended  to  be  used  as  a  diuretic 
in  doses  of  0-25  three  or  four  times  a  day.    It  may  also  be  used
