over  each  cylinder  and  around  another  cylinder  running  parallel, 
supported  on  a  pinion  attached  to  an  arm  extended  on  either  side 
from  the  main  support.  The  mass  was  fed  in  between  the  bands, 
which,  from  their  elasticity,  took  the  shape  of  the  matrices  when 
pressed  on  by  the  pill-mass,  and  after  passing  the  point  of  con- 
tact, the  bands,  by  contracting,  forced  out  the  pills.  The  objec- 
tion to  this  arrangement  appears  to  be,  that  the  bands  after  use 
for  a  time,  are  cut  by  the  sharp  edges  of  the  moulds  and  be- 
come useless. 
Harris's  Patent  Sieve. — 
By  a  singular  misunder- 
standing, the  invention  of 
the  Patent  Sieve  figured  in 
the  margin,  and  which  was 
described  in  our  last  num- 
ber, was  ascribed  to  Mr. 
Swift,  the  inventor  of  the 
drug-mill  bearing  his  name. 
This  instrument  is  the  in- 
vention of  Mr.  Saml.  Harris 
of  Springfield,  Mass.,  who 
has  made  Charles  Ellis  &  Co

Oantharides. — The  true  Lytta  vestcatoria  is  unknown  both  in 
Greece  and  in  the  oriental  countries.  The  Mylabris  cichorii 
and  M.  variegata  are  generally  substituted.  These  genera  are 
readily  distinguished  from  cantharides  by  their  color  and  general 
appearance.  They  are  tolerably  abundant  throughout  the  entire 
East.  Landerer  observed  them  in  Smyrna  and  in  Constantinople, 
in  the  month  of  August.  In  Greece  they  are  seen  more  especially 
during  May  and  June.  They  are  the  Greek  chrysomyga,  and 
are  used  for  vesicating  purposes  by  being  made  into  a  plaster  or 
cataplasm,  with  honey  or  bread.  This,  after  a  few  hours,  pro- 
duces considerable  irritation  and  redness,  followed  by  vesication.
