This  is  so  well  shown  by  the  legends. 
(1)  Let  each  one  work  in  the  business  he  knows. 
(2)  Let  each  one  exercise  himself  in  the  art  which  he  knows. 
(3)  The  legend  of  the  seal,  which  goes  further  and  tells  the  mem- 
bers that  it  is  safety  to  know  all  these  things. 
Let  us  all  heed  the  lessons  that  the  worthy  pioneers  of  pharmacy 
so  wisely  planned  and  worked  so  earnestly  to  carry  out  their  plans 
when  organizing  our  College ;  then  our  present  pharmacists  will 
live  in  the  kind  remembrances  of  their  successors  when  they  have 
left  their  active  labors  to  younger  hands.

"  First  Book  of  Qualitative  Chemistry,"  for  studies  of  water  solu- 
tion and  mass  action.  By  Albert  B.  Prescott  and  Eugene  C.  Sulli- 
van. Eleventh  edition,  entirely  rewritten.  New  York :  D.  Van 
Nostrand  Company,  1902.    Price,  #1,50; 
The  first  edition  of  Prescott's  "  First  Book  of  Qualitative  Chemis- 
try "  appeared  in  1879.  The  successive  editions  were  favorably 
received  by  students  of  chemistry  in  the  high  schools,  colleges  and 
universities,  as  the  work  not  only  contained  the  information  the 
students  desired,  but  it  was  clear  and  concise  and  free  from  any 
ambiguity.  The  objective  point  of  the  author  was  not  that  the  stu- 
dent might  only  secure  the  results  and  carry  on  analysis,  but  that 
primarily  he  might  have  "  a  personal  acquaintance  with  the  character 
of  the  chemical  elements  and  with  the  nature  of  chemical  change." 
The  eleventh  edition  contains  all  of  the  valuable  features  ot  the 
earlier  editions,  in  that  the  grouping  of  the  elements  is  according  to 
the  Periodic  System,  and  the  composition  of  materials  occurring  in 
daily  life  are  given  in  a  large  number  of  instances.  In  addition,  the 
work  has  incorporated  in  it  the  results  of  the  fundamental  researches 
of  Ostwald  in  inorganic  and  analytical  chemistry.

The  study  of  the  chemistry  of  volatile  oils  has  attracted  the  atten- 
tion of  chemists,  botanists  and  pharmacists  for  years.  During  the 
last  twenty  years  Wallach  and  others  have  developed  by  their
