46  SYRUPUS  SENEGA. 
one-fourth  the  liquid,  leaving  the  supernatant  portion  perfectly 
clear,  limpid,  and  of  a  red-brown  color.  In  odor  and  taste  it 
corresponded  with  I  and  kept  very  well. 
III.  Syrup  prepared  February,  1867,  like  II,  with  which  it 
corresponded  in  appearance  and  properties,  with  the  exception 
that  C  had  formed  a  small  amount  of  mould  on  its  surface  during 
the  summer  months. 
IV.  Syrup  prepared  in  September,  1866 ;  the  root  was  extracted 
with  a  menstruum  of  3  measures  of  alcohol  0*835  to  2  measures 
of  water  ;  otherwise  the  officinal  directions  were  followed.  In 
appearance  and  properties  it  corresponded  most  closely  with  I, 
like  which  it  has  formed  no  deposit  up  to  date.  The  portion  C, 
however,  formed  a  small  amount  of  mould,  somewhat  more 
abundant  than  III. 
V.  Syrup  prepared  in  September,  1866,  differing  from  the 
officinal  by  the  use  of  a  menstruum  of  2  measures  of  alcohol 
0-835  to  1  measure  of  water.  It  was  not  clear,  and  shortly  a 
flocculent  matter  separated  and  rose  to  the  surface  in  B  and  (7, 
which  otherwise  kept  very  well  ;  A  remained  uniform.  This 
syrup  was  of  a  brown-red  color  and  did  not  differ  materially  in 
taste  or  odor  from  I. 
VI.  Syrup  prepared  in  February,  1867,  differing  from  the 
officinal  by  the  use  of  alcohol  0*835  as  menstruum.  It  was  of  a 
light  yellow  color,  not  quite  clear,  and  formed  a  flocculent  pre- 
cipitate on  standing  a  few  days.  In  odor  and  taste  it  was  de- 
cidedly inferior  to  the  previous  lots. 
VII.  Syrup  prepared  in  February,  1867,  in  the  officinal  pro- 
portions, by  exhausting  the  root  by  displacement  with  cold 
water,  evaporating  to  the  consistence  of  a  thin  extract,  which 
was  exhausted  with  cold  alcohol  0*835,  the  alcoholic  tincture 
evaporated  to  expel  alcohol,  the  residue  taken  up  by  water  in 
the  proper  proportion  and  converted  into  syrup.  This  formed  a 
beautiful  clear  syrup,  of  a  red-brown  color,  limpid  and  perma- 
nent. In  odor  it  was  inferior  to  the  other  syrups,  and  it  did  not 
possess  their  aromatic  taste,  but  in  acrimony  it  is  equal  to  any 
of  them.    A  small  amount  of  mould  formed  on  C. 
VIII.  Syrup  prepared  March,  1867,  like  VII,  possessing  the
