gilding  and  silvering  pills  is  very  inconvenient,  for,  if  it  be  perfectly 
done,  the  pills  will  be  effectually  preserved  from  the  action  of  the 
stomach." 
A  tincture  of  strychnine  is  directed  to  be  prepared  of  a  strength 
of  three  grains  to  the  ounce,  and  a  mixture  of  strychnine  which  is  a 
suspension  of  the  alkaloid  in  sweetened  water  of  the  strength  of  one- 
half  grain  to  the  ounce. 
Emetine  is  directed  to  be  prepared,  as  may  be  expected,  from 
ipecacuana.  An  emetic  mixture  of  emetine  of  a  strength  of  nearly 
two  grains  to  the  ounce  in  sweetened  orange  flower  water  is  described. 
Pectoral  Lozenges  of  Emetine  containing  about  one-seventh  grain 
of  emetine  in  each  dose  are  described  as  are  also  Emetic  Lozenges  of 
Emetine  containing  over  one-half  grain  each  of  the  alkaloid.  A 
Syrup  of  Emetine  containing  sixteen  grains  of  emetine  to  the  pound 
is  also  directed. 
Another  and  purer  form  of  emetine  is  also  described  and  formulas 
given  for  preparations  containing  it  in  which  one-fourth  as  much  is- 
directed  to  be  taken  of  the  pure  Emetine  as  was  directed  in  the  corre- 
sponding preceding  preparations. 
Cytisine  is  a  poisonous  vegetable  principle  from  the  seeds  of  the 
Laburnum.    No  medicinal  properties  or  uses  are  given. 
Quinine  and  Cinchonine  take  up  about  twenty  pages  of  the  work. 
The  species  of  cinchona  mentioned  are  C.  cordifolia,  C.  condaminea 
and  C.  oblongif olia ;  none  of  these  species  are  recognized  by  the 
Pharmacopoeia  of  to-day.  Methods  fof  preparing  these  alkaloids 
are  described,  the  cinchonine  being  obtained  from  the  mother  liq- 
uors after  separating  the  quinine. 
The  percentage  composition  of  quinine  as  given  does  not  compare 
as  favorably  with  modern  figures  as  does  that  of  morphine,  due 
undoubtedly  to  the  mixture  of  alkaloids  which  was  then  known  by 
the  same  quinine.

There  were  two  sulphates  of  quinine  described,  one  called  Qui- 
nine Super  Sulphate  (acid  sulphate  of  quinine).    The  other  was
