Actions  and  Uses. — Gallogen  is  an  astringent  and  antidiarrheic, 
slowly  decomposed  in  the  intestinal  tract,  thus  exerting  its  astrin- 
gent action  gradually  during  its  passage.  It  has  been  recommended 
in  dysentery,  cholera  infantum,  diarrhoea,  and  is  said  to  be  useful 
even  in  those  of  a  syphilitic  or  tuberculous  origin.  Dosage. — 0-3  to 
0-5  gramme  (5  to  8  grains)  for  children  ;  0  6  to  I  gramme  (10  to  15 
grains)  for  adults,  suspended  in  neutral  or  slightly  acid  media.

GLYCEROPHOSPHATES.  GLYCERINOPHOSPHATES.  GLYCERYLPHOSPHATES. 
Glycerophosphates  are  the  salts  of  glycerophosphoric  acid, 
H2(CH2OH.CHOH.CH2)P04 ;  usually  the  two  remaining  hydrogen 
atoms  of  phosphoric  acid  are  replaced  by  the  base:  Na2(CH2OH. 
CHOH.CH2)P04. 
Actions  and  Uses. — These  salts  were  introduced  as  "  nerve  foods  " 
and  tonics  on  the  theory  that  their  phosphorus,  being  a  step  nearer 
lecithin,  is  assimilated  more  readily  than  that  of  hypophosphites. 
Neither  the  experimental  nor  the  clinical  evidence  is  considered 
conclusive  by  all  authorities.  Dosage. — The  potassium  and  sodium 
salts  may  be  given  hypodermically  0-2  to  0*25  gramme  (3  to  4  grains) 
in  normal  saline  solution,  or  per  os  0-25  to  0-65  gramme  (4  to  10 
grains)  in  water  or  syrup.  The  calcium,  iron,  lithium,  magnesium 
and  manganese  salts  0*2  to  0  65  gramme  (3  to  10  grains)  doses, 
preferably  in  the  form  of  tablets;  the  quinine  salt  in  O-i  to  0-33 
gramme  (\y2  to  5  grains),  and  the  strychnine  salt  in  OOOI  to  0-003 
gramme  ^  to      grain)  doses. 
GUAIAMAR. —  GUAIACOLGLYCERYLESTER. 
Guaiamar,  C6H4.OCH3.0  (CH2OH.CHOH.CH2),  1:2,  =  C10HuO4, 
is  the  monoguaiacol  ester  of  glycerin. 
Actions  and  Uses. — The  chief  value  of  guaiamar  arises  from  the 
liberation  of  guaiacol,  partly  in  the  stomach  and  partly  in  the  intes- 
tinal canal,  being  split  up  by  the  gastric  and  intestinal  contents  with 
the  assimilation  of  one  molecule  of  water  into  guaiacol  and  glycerin. 
By  this  evolution  of  guaiacol  it  is  believed  to  exert  a  useful  antiseptic 
action  in  the  intestinal  canal.  Moreover,  it  is  asserted  that  it  is 
absorbed  by  the  skin  as  readily  as  by  the  alimentary  canal,  and 
that  it  is  without  effect  on  the  sound  tissue,  but  becomes  effective 
at  the  location  of  the  diseased  part.    It  is  said  not  to  interfere  with
