    • Abstract


      1. A typical sample of samarskite has been analysed and the results reported.

      2. The thoria content of the sample is 1·98%.

      3. The percentage of cerium earths present in this sample is relatively much smaller than found in samples from North America. Our sample contains 0·4% ceria.

      4. Hexavalent uranium has not been found in the sample but this is of no special significance.

      5. The radium contents is 1·0 gr. in 39· 71 tons and the Nellore samarskite is nearly as rich as Katanga Carnotite in this element.
