PsiLOJIKLANIs. r.LAf'K OxiDE OF MaNGANESE. WaD. 



This ore is of doubtful occurrenoo in Burma, though Dr. Mason sa3's it occurs 

 on some islands of the Mergui Archipelago. Tlie bed of " Wad " I'epoi'ted by Capt. 

 Tremenheere on the Tenasserini was found by l\Ir. Piddington to contain no trace 

 of ui.anganeso, but to consist of a peculiar graphitous substance, between coal anil 

 graphite, which he named '■Tremeulicorito," but its claim to be regarded as a mineral 

 species is verj' doubtful. The jiaragraph therefore recording the existence of man- 

 ganese, at p. G4 of tho British Burma Uazctteer, should be expunged. 



QuAUTZ. Silica. 



Besides the ordinary varieties of quartz, green and yellow quartz are stated by 

 Dr. Mason to be found in the Tenasserini Provinces, and carnelian called by the 

 Burmese Kijal-tliwe ' fowl's blood.' As the red colour, however, is artificially induced 

 by burning or baking, it may be questioned if the stone is found originally in the 

 Province. The carnelian of commerce is derived from the trap rocks of Western 

 Inilia, and tho carnelian mines at Kajpipla are siru[)ly gravel-pits. The rough 

 carnelians are placed in earthen pots, and baked, and the " red " carnelians which 

 result are then sold. Dr. Mason also records agates as found at Mopoon and IMei'gui, 

 but their occurrence requires confiruiation, also amethyst. " Pebbles of amethyst, or 

 violet quartz, are brought from the mines in Burma, where tliey are regarded as a 

 variety of the sapphire ; the Burmese name signifying ' egg-plant sapphire,' or, as 

 they are sometimes called, ' egg-plant flower stoue,' from the blue flower of tho 

 egg-plant." 



Agates may be divided into two classes, banded agates, to which class onyx and 

 sardonj'x may be referred, and " Moss " agates, which are sponges or other organisms 

 preserved in flint, and are of course confined to sedimentary rocks. Mocha stones 

 are banded agates with the appearance of filaments of moss between the layers. 

 These filaments are however inorganic, and merely dendritic cr3'stals of iron and 

 manganese. Some chalcedonies closely resemble true "moss" agates when clouded 

 with red proxide of iron or greeu earth. It is doubtful if either class of agates occur 

 in Burma. 



B. TEBNAEY COMPOUNDS. 



Pyroxene or Augite. 

 A constituent of the volcanic rocks of Puppadoung, etc. 



Amphibolic or Hornblende. 



A constituent of some metamorijliic rocks of Burma. Under this head are 

 included tremolite, actinolite, asbestos, and jade. This last is an important article 

 of export from Upper Burma. Its colours (Burmese or precious jade) vary from 

 pearly grey or whitish to light muddy or leek green or dark green. Rolled pebbles 

 of this are exteriorly rusty-coloured. A highly-prized variety is a pale grey with
