tion  of  bubbles.  Then  the  mouth  of  the  tube  is  held  slanting  on  an 
object  glass  and  with  the  platinum  loop  a  droplet  is  spread  all  over 
the  object  glass,  and  two  other  slides  are  prepared  in  the  same  way. 
Before  drawing  out  the  sediment,  the  loop  is  singed  to  be  sure  that 
no  undissolved  albumin  is  sticking  to  it.  He  regards  the  method  as 
extremely  practical  and  instructive.  His  first  publication  on  the  ad- 
vantages of  impregnation  of  the  sediment  with  human  serum  date 
from  1914.  (C.  Minerbe.  Rivista  Critica  di  Clinica  Medica,  Flor-

EUPATORIUM   GLUTINOSUM   LAM.  SUBSTITUTED  FOR  MATICO  N. 
F. — Examination  of  importations  of  "matico  leaves"  {Piper  an- 
gusti folium  Ruiz  et  Pavon)  has  disclosed  that  in  one  instance  the 
leaves  of  Eupatorium  glutinosum  Lam.  have  been  substituted  for 
the  true  material.  Piper  angustifolium  has  alternate  leaves,  which 
have  a  finely  crenulate  margin,  unequal  subcordate  base,  a  finely 
bullate  upper  surface,  and  prominent  venation  below,  and  have  no 
glandular  hairs ;  whereas  Eupatorium  glutinosum  has  opposite 
leaves,  which  have  a  serrate  margin,  cordate  base,  coarsely  bullate 
upper  surface,  and  numerous  glandular  hairs.  The  flowers,  which 
occur  occasionally  in  samples  of  the  leaves,  consist  of  a  spike  in  the 
case  of  matico  and  of  a  cymose  paniculate  composite  head  in  the 
case  of  Eupatorium  glutinosum.  The  department  will  recommend 
the  detention  of  shipments  of  "matico  leaves"  found  to  consist  in 
whole  or  in  part  of  the  leaves  of  Eupatorium  glutinosum. — Service

Greek  Sage  and  Spanish  Sage  Substituted  for  Sage  (Salvia 
Officinalis). — Examination  by  the  bureau  of  commercial  samples 
of  "  sage  "  has  disclosed  that  in  some  instances  the  samples  were  not 
obtained  from  Salvia  officinalis  L.,  but  consisted  of  the  leaves  of 
Greek  sage,  Salvia  triloba  L.,  and  Spanish  sage,  Salvia  lavandulce folia 
Vahl.  These  forms,  while  very  closely  related  to  true  sage,  have 
certain  differences  in  appearance  and  flavor,  and  are  well  recognized 
by  the  trade  as  distinct  forms.  Greek  sage  may  be  distinguished 
from  true  sage  by  the  usually  broader,  shorter,  thicker,  entire  leaves, 
short  petioles,  and  by  their  more  wooly  appearance.  Spanish  sage 
may  be  distinguished  by  its  smoother,  considerably  smaller,  entire 
leaves  and  relatively  long  petioles.    Neither  Greek  sage  nor  Spanish
