simply  called  Quinine  Sulphate.  These  correspond  to  our  present 
day  bisulphate  and  sulphate,  respectively. 
The  following  formulas  were  proposed  for  the  administration  of 
these  alkaloids : 
S3n:up  of  Quinine,  thirty-two  grains  to  the  pound. 
Wine  of  Quinine,  twelve  grains  to  the  litre. 
Tincture  of  Quinine,  six  grains  to  the  ounce. 
Syrup  of  Cinchonine,  forty-eight  grains  to  the  pound. 
Wine  of  Cinchonine,  eighteen  grains  to  the  litre. 
Tincture  of  Cinchonine,  nine  grains  to  the  ounce. 
Under  Veratrine  we  find  a  confusion  of  fact  and  error.  This 
"new  alkali"  is  stated  to  exist  in  the  seed  of  Veratrum  Sabadilla 
(which  is  correct),  and  in  white  hellebore  (which  is  incorrect,  al- 
though excusable),  and  in  colchicum  (which  is  a  startling  and  inex- 
cusable error).  The  only  method  for  its  preparation,  however,  is 
that  from  Sabadilla  seeds,  although  some  space  is  given  in  this  chap- 
ter to  the  therapeutic  effects  of  colchicum. 
Hydrocyanic  Acid  or  Prussic  Acid  is  described  both  as  to  its  prop- 
erties and  its  mode  of  preparation.  Formulas  are  given  of  prepara- 
tions for  its  administration  and  use.    Among  these  are: 
Mistura  Acidi  Hydrocyanici  (Melange  pectoral — Magendie) 
Medicinal  Prussic  Acid   i  gros  (59.07  grains  troy) 
Distilled  Water   i  lb.  (15  oz.  6  dr.  i  grain  troy) 
Pure  Sugar   i  V2  oz.  (11  dr.  10  grains  troy) 
Dose — One  dessert  spoonful. 
Potio  Acidi  Hydrocyanici  (potion  pectoral — Magendie) 
Infusion  of  Ground  Ivy   2  oz.  (i  oz.  7  dr.  45  grains  troy) 
Medicinal  Prussic  Acid   15  drops 
Syrup  of  Marshmallows   Z  oz.  (7.52  dr.  troy) 
Dose — One  dessert  spoonful. 
Syrupus  Acidi  Hydrocyanici  (Hydrocyanic  Syrup) 
Clarified  Syrup   i  lb.  (15  oz.  6  dr.  i  grain  troy) 
Medicinal  Prussic  Acid   i  gros  (59.07  grains  troy) 
The  medicinal  Prussic  Acid  above  directed  is  described  as  being 
made  from  absolute  HCN,  by  diluting  it  with  8.5  times  its  weight 
of  distilled  water.  This  produces  an  acid  of  about  ten  per  cent, 
strength,  which  is  stated  to  be  of  greater  uniformity  of  strength  than 
that  produced  by  Scheeles  process  which,  however,  is  not  described 
but  is  mentioned  as  being  usually  of  about  half  the  strength  of  the 
author's.    The  curious  precautionary  note  is  attached  to  all  of  the
