A%JP°rlii;S4arm'}  Analysis  of  Pycnanthemum  Linifolium.  169 
Of  course,  in  such  words  as  tcpeaypa,  meat-hook,  the  first  part  of 
the  word  is  not  /cpea,  but  /cpe,  the  second  word  being  a<ypa.  As 
this  begins  with  a  vowel,  the  binding-vowel  0  is  not  inserted. 
It  is  curious  that,  as  regards  the  fuller  stems  xpear  (from  /cpea$, 
flesh),  and  /cepar  (from  /cepas,  horn),  only  the  latter  appears  as  first 
part  of  a  compound.  There  are  no  compounds  beginning  with 
/cpear  in  the  actual  language,  but  modern  authorities  have,  quite 
correctly,  employed  it  in  the  formation  of  new  words,  viz :  creat-ic, 
creat-in,  and  creat-inin. 
From  the  above  it  will  appear  that  the  form  "  creosote  "  is  that 
most  in  harmony  with  Greek  usage. 
The  spelling  "  creasote  "  appears  now  only  in  the  British  Phar- 
macopoeia, and  in  various  unofficial  works  of  reference,  price-lists, 
etc.    All  other  pharmacopoeias  spell  the  word  with  "  o." 
ANALYSIS  OF  PYCNANTHEMUM   LINIFOLIUM,  WITH 
ADDITIONAL  NOTES  ON  P.  LANCEOLATUM.

No.  132. 
This  analysis  was  made  in  the  Chemical  Laboratory  of  the  Phila- 
delphia College  of  Pharmacy,  at  the  request  of  Prof.  Henry  Trimble, 
and  under  his  supervision. 
A  qualitative  investigation  of  P.  linifolium  was  made  in  the  year 
1876,  by  Dr.  Charles  Mohr,  whose  paper  on  the  subject  was  pub- 
lished in  the  Proceedings  of  the  American  Pharmaceutical  Associa  - 
tion, Vol.  24,  p.  513. 
The  plants  used  in  the  present  analysis,  as  in  the  case  of  P.  lanceo- 
latum,  the  analysis  of  which  was  published  in  the  February  issu 
of  the  Journal,  were  collected  in  Delaware  County,  Pa.,  in  the  sum- 
mer^of  1893,  when  in  flower,  and  were  cut  off  a  few  inches  above 
the  ground.  The  drying  was  effected  without  exposure  to  sun- 
light or  artificial  heat,  with  a  loss  of  about  60  per  cent,  of  the 
weight. 
The  estimations  were  made  by  the  same  methods  as  those  employed 
in  the  corresponding  estimations  in  the  analysis  of  P.  lanceolatum, 
with  the  exception  of  the  estimation  of  the  ethereal  oil,  which  was 
made  by  bringing  the  benzol  extract,  previously  dried  at  iOO°,  to
