Entire  hairs  ranged  in  length  from  770  to  1300/x  in  the  case  of 
Ceylon  Nux  Vomica,  630  to  980/1  in  the  Tellicherry,  630  to  700// 
in  the  Madras,  and  630  to  980 /x  in  the  Cochin  variety.  The  longest 
hairs  were  noted  on  the  Ceylon  Nux  Vomica,  but  the  other  observ- 
ances demonstrated  little  in  the  way  of  diagnostic  differences.  When 
viewed  under  polarized  light  the  hairs  of  all  varieties  presented  the 
same  striking  appearance.  Measurements  determined  for  the 
outer  endosperm  cells  averaged  as  follows: 
These  cells  appeared  more  regularly  rectangular  in  the  Telli- 
cherry than  in  the  other  varieties.

MAKING  USE  OF  NATIONAL  AND  STATE  BULLETINS 
UPON  SCIENTIFIC  SUBJECTS.* 
"Know  your  opportunity,"  said  Pittacus,  one  of  the  seven  wise 
men  of  ancient  Greece. 
One  of  the  usually  unrecognized  opportunities  of  acquiring 
information  and  of  accumulating  a  valuable  collection  of  reference 
pamphlets  is  that  afforded  by  the  publications  of  the  Scientific 
Bureaus  of  both  State  and  Nation. 
Many  of  the  inquiries  which  come  to  the  pharmacist  from  his 
patrons  are  upon  subjects  which  are  not  directly  related  to  his  pro- 
fession, at  least  not  so  closely  as  to  be  found  in  any  of  the  text- 
books or  works  of  reference  that  may  be  upon  his  bookshelf,  and 
yet  closely  enough  to  make  him  the  one  logical  person  in  a  com- 
munity to  whom  such  inquiries  should  be  addressed.
