854 of the polish, but it is developed by a little acid, or washing. Seine fragments have a flat striated structure like lignite; these are less bright in color, and heavier; they burn with copious flame, and some emission of sparks. The water given out on the .andhea*, is 3.5 in the first and 5.4 in the second sort. Specific gravity No. 1, of No. 2 1.227 1.481 Composition—volatile matter, 49.1 48.6 Carbon 48.5 46.3 Eartby matter, ferruginous, 2.4 6.1 100.0 100.0

The tin box, on arrival, was found to contain fragments of coal, and some large nodules of iron pyrites, the hardness of which had h.’erad most of the coal to atoms on its way down. Some pieces, however, were picked out, which had a very promising appearance, more reeom blmg the Burdwa.e coal than any of the above. Some pieces, however, were attached to black silicified, or fossil, wood, which at fiat sight might be mistaken for excellent coal. It had .a suiphurous smell from the pyrites, and from the analysis I fear it is much adulterated with this mineral. From its aqueous contents, 7.8 per cent., it scmtillates a good deal in burning, and th. flame is peculiarly coloured from the presence of metals.

The specific gravity is 1.580 and the composition of a selected piece Volatile matter 48.1 Carbon, 39.3 Ferruginous residue from the pyrites ? 12.6 100.0

More information will be desirable regarding this S..tl.j coal, whith premises to be a valuable addition to omer now extended catalogue of Indian coal deposits: but its locality at Man4i is too far from the limit, of navigation, to allow of its being brought practically into me.
