Hie  Hardness  of  Silver. — Goldsmiths  often  complain  of  the  hardness  of 
silver,  which  is  sometimes  very  difficult  to  carve,  and  presents  a  dead  grey 
cut.  These  properties  are  generally  attributed  to  the  presence  of  a  foreign 
metal :  but  M.  Mathey,  assayer  at  Locla,  has  shown  that  in  this  silver 
there  is  neither  tin,  lead,  nor  any  other  injurious  metal.  Ho  considers  this 
property  to  be  due  solely  to  the  high  temperature  at  which  silver  is  cast. 
By  letting  the  crucible  cool  till  a  slight  solid  crust  is  formed  on  the 
surface  of  the  fused  metal,  and  casting  at  this  moment,  a  soft  silver  with  a 
brilliant  cut  is  obtained. —  Chem.  News,  Sept.  1866,  from  Dingler's  Poly-

Rhceadine. — Hesse,  looking  for  morphia,  has  discovered  a  new  alkaloid 
in  the  red  poppy  ;  it  is  also  to  be  found,  he  says,  in  good  opium.  It  is 
•  soluble  in  water,  alcohol,  and  ether,  crystallizing  from  the  last  in  white 
prisms.  Ammonia  precipitates  it  in  white  crystalline  flocculi,  bichloride 
of  mercury  gives  a  white  amorphous  precipitate,  chloride  of  gold  a  yellow 
precipitate.  Strong  acids  decompose  it  in  the  cold,  giving  a  purple  solu- 
tion. The  author  promises  to  publish  his  method  of  extracting  Ehoeadine.
