Deterioration  of  Syrup  of  Wild  Cherry. 
By  J.  Graham  French. 
The  author  gives  the  method  of  determination  and  results  in  a 
series  of  experiments  to  determine  just  how  long  after  date  of 
manufacture  the  hydrocyanic  acid  in  syrup  of  wild  cherry  disappears. 
Three  lots  of  syrup  were  prepared  and  tested.  In  each  case  about 
10  c.c.  was  distilled  by  passing  live  steam  into  the  syrup.  To  the  dis- 
tillate was  added  a  mixture  of  ferric  chloride  and  ferrous  sulphate, 
the  latter  being  in  excess.  The  solution  was  then  made  alkaline  with 
sodium  hydrate  solution  and  the  precipitate  formed  dissolved  by  the 
addition  of  hydrochloric  acid.  A  blue  or  green  color  was  taken  as 
an  indication  of  the  presence  of  hydrocyanic  acid. 
He  says  that  he  feels  justified  in  stating  that  the  acid  disappears 
within  3  or  4  months  after  date  of  preparation.

How  Should  Retail  Druggists  Keep  Leeches? 
By  W.  A.  Pearson. 
The  author  endeavored  to  determine  whether  leeches  would  be 
longer-lived  kept  in  a  jar  covered  with  cheese  cloth,  containing  200 
grammes  of  animal  charcoal  and  1000  c.c.  of  water,  or  the  orthodox 
way  of  a  tin  can,  with  moist  earth.
