SYRUPUS  AMYGDALAE. 
By  F.  W.  Haussmann. 
On  account  of  the  liability  of  decomposition,  syrup  of  almond 
is  best  prepared  recently,  although  such  is  not  stated  specifically  by 
the  Pharmacopoeia.  For  extemporaneous  preparation  the  present 
official  formula  is  more  suitable  than  those  of  former  editions. 
The  official  directions  are,  however,  liable  to  cause  confusion  in 
several  respects. 
In  the  summary  of  the  quantities,  200  c.c.  of  water  are  ordered, 
whereas  in  the  directions  for  manipulation  330  c.c.  are  used.  The 
final  measure  is  directed  to  be  made  up  to  1,000  c.c.  with  water, 
where  syrup  is  obviously  intended.  A  point  in  the  directions  may 
also  be  called  attention  to.  The  almonds  are  directed  to  be  rubbed 
in  a  mortar  w  th  100  grammes  of  sugar  and  30  c.c.  of  water  to  a 
smooth  paste.  With  the  given  amount  of  water  only  a  mass  can  be 
obtained  and  the  quantity  used  for  trituration  should  be  increased. 
In  comparison  with  the  formula  of  the  1880  Pharmacopoeia,  the 
present  one  is  to  be  preferred.  While  trituration  of  the  almonds 
with  a  larger  quantity  of  water  may  produce  a  more  perfect  emul- 
sion, cohesion  is  destroyed  if  the  sugar  is  dissolved  by  agitation. 
Continental  pharmacopoeias  direct  a  greater  sugar  percentage  and.
