enlarged  about  four  diameters.)  The  florets  of  the  true  insect  powder 
are  somewhat  larger  than  those  of  the  Hungarian  Daisy. 
The  Hungarian  Daisy  is  distinguished  from  the  true  Pyrethrum  by 
the  orange  yellow  disk  florets,  by  the  depression  of  the  involucre,  by 
its  prominent  dark  receptacle  and  the  absence  of  pubescence  and 
pappus.  The  odor  is  less  pungent  than  that  of  the  true  insect  flower 
being  more  like  that  of  matricaria.  The  difference  in  odor  is  more 
pronounced  on  infusing  in  warm  water.  The  Hungarian  Daisy  yields 
a  powder,  somewhat  darker  in  color.  This  powder  used  upon  flies 
and  cockroaches  appeared  to  have  no  value  as  an  insecticide.  Micro- 
scopically no  difference  could  be  detected  between  the  two  powders. 
Time  and  the  amount  of  material  at  my  command  would  not  per- 
mit of  a  thorough  chemical  examination,  but  it  was  hoped  that  the 
percentage  of  extractive  matter  obtained  with  various  solvents  might 
furnish  a  useful  comparison.  The  following  statement  exhibits  the 
results  obtained.

The  following  description  of  the  above  plant,  together  with  the  ma-
