This  is  a  silver  white  alloy  composed  of  aluminum  and  magne- 
sium. It  is  not  affected  by  air  and  water,  and  even  withstands  the 
oxygen  acids  to  a  great  extent,  but  is  attacked  by  alkalies.  The 
specific  gravity  ranges  from  2  to  2-2  at  150  C.  It  can  be  rolled  into 
sheets  and  drawn  into  wire.  The  reflective  power  is  very  high, 
and  it  does  not  absorb  the  ultra-violet.  These  properties,  together 
with  its  low  density  and  high  rigidity,  make  it  a  very  superior  ma- 
terial for  specula. — Brit.  Jour.  Phot.,  1900,  47,  2090. 
The  recently  opened  up  mining  district  near  Iterbira,  Brazil,  is 
producing  a  large  quantity  of  very  pure  black  oxide  of  manganese. 
This  ore  is  apparently  the  remains  of  a  manganiferous  limestone 
from  which  the  limestone  has  been  removed.  It  is  a  hard  metallic- 
looking  ore,  interstratified  with  about  20  per  cent,  of  the  hydrated 
manganese,  which  seems  to  contain  the  greater  amount  of  the  im-
