convex,  rarely  2-3  compound  (Fig.  9).  These  have  an  average 
range  of  3  to  28  jn  in  diameter.  Occasionally  somewhat  elongated 
rovoid-shaped  grains  are  seen  which  attain  a  length  of  40  fx. 
Radicle. — This  shows  the  usual  cucurbitaceous  structures  typical 
for  that  portion  of  the  embryo.  The  cells  of  the  cortex  are  rich  in 
protoplasm,  have  prominent  nuclei,  but  are  entirely  devoid  of  starch. 
Uses  of  Chayote. — The  fruits  should  be  picked  from  vines  when 
but  two  thirds  or  three  fourths  grown.  They  lose  their  delicate 
flavor  and  become  tough,  if  allowed  to  mature.  They  are  then  cut 
into  halves  or  quarters  and  boiled.  The  boiled  fruit  can  be  creamed, 
baked,  fried,  or  made  into  fritters,  sauces  or  salads,  similar  to  the 
squash. 
The  vines,  tuberous  roots  and  fruits  may  be  used  as  fodder  for 
stock.  The  woody-stems  furnish  a  fine  fiber  known  to  the  French 
as  (C  paille  de  chouchon"

CONSTRUCTIVE  SUGGESTIONS  FOR  THE  REVISION 
OF  THE  PHARMACOPCEIA.1 
By  Dr.  Fred.  B.  Kilmer, 
NEW  BRUNSWICK,  N.  J. 
"  Great  economic  and  social  forces  flow  with  tidal  sweep  over  communi- 
ties only  half  conscious  of  that  which  is  following  them.  Wise  statesmen  are 
those  who  foresee  what  time  is  thus  bringing,  and  try  to  shape  institutions 
and  to  mold  men's  thoughts  and  purpose  in  accordance  with  the  change  that 
is  silently  surrounding  them." — Viscount  Morley. 
We  see  the  curtain  lifted  upon  the  tenth  revision  of  the  United 
States  Pharmacopoeia.  Each  decennial  revision  of  the  Pharma- 
copoeia has  marked  an  era,  and  this  one  perhaps  more  than  all  that 
have  gone  before.  A  pharmacopoeia,  such  as  ours,  more  than  any 
single  volume,  records  the  progress  of  medicine,  of  pharmacy,  of 
surgery  and  of  allied  sciences.
