try  rest  as  well  as  training  in  the  application  of  the  knowledge  thus 
acquired,  is  admirably  adapted  to  fit  a  man  to  become  an  expert 
not  only  in  the  microscopical,  but  also  in  the  chemical  examination 
of  foods  and  drugs."  Again  and  again  is  one  reminded  in  this 
work  of  Greenish's  of  the  observation  of  Hassall  in  regard  to  the 
application  of  the  microscope  "  that  there  is  scarcely  a  vegetable 
article  of  consumption,  not  a  liquid,  which  may  not  be  distinguished 
by  means  of  that  instrument.  Further,  that  all  those  adulterations 
of  these  articles  which  consist  in  the  addition  of  other  vegetable 
substances  and  which  constitute  by  far  the  majority  of  the  adultera- 
tions practised,  may  likewise  be  discovered  and  discriminated  by  the 
same  process."  Furthermore,  Greenish  calls  attention  to  the  fact 
that  the  "  Investigations  recently  conducted  by  the  Society  at  the 
request  of  the  General  Medical  Council  have  also  shown  that  the 
microscopical  examination  of  powdered  drugs  yields  results  of  far 
greater  value  in  determining  their  identity  and  purity  than  such 
chemical  data  as  the  amount  of  ash  yielded  by  them."  In  view 
of  the  splendid  work  done  by  Greenish  this  work  will  do  much 
in  making  a  rational  consideration  of  the  subject  of  pharmacognosy 
possible  and  cause  students  and  pharmacists  to  be  willing  to  devote 
a  sufficient  amount  of  time  to  the  mastery  of  the  principles  involved 
in  the  work. 
SUSAN  HAYHURST. 
The  memorial  exercises,  held  at  the  Philadelphia  College  of 
Pharmacy  on  November  15,  1910,  in  connection  with  the  presentation 
to  the  college  of  a  portrait  of  Dr.  Susan  Hayhurst,  were  a  worthy 
tribute  to  this  pioneer  woman  pharmacist,  to  whom  the 
majority  of  the  women  graduates  of  the  Philadelphia  College  of 
Pharmacy  are  indebted  for  the  opportunity  she  gave  them  to  acquire 
a  knowledge  of  the  practical  side  of  pharmacy. 
Dr.  Hayhurst  matriculated  in  the  Philadelphia  College  of  Phar- 
macy in  1879,  at  the  age  of  59,  and  graduated  four  years  later. 
During  her  more  than  thirty  years  of  service  as  apothecary  of  the 
Woman's  Hospital  of  Philadelphia  she  gave  employment  to  some 
sixty-five  young  women,  a  number  of  whom  were  present  on  this 
occasion  and  contributed  to  the  testimonial  held  in  honor  of  prob-
