clases, and in one instance {viz., in a specimen collected on the road 
between Mogok and Momcit), the epidote has the pecuHar colour and 
pleochroism of withamite, due, no doubt, to the fact that it contains 
some manganese.' 
Sagaing District. 
Among some minerals received from Ava and forwarded by Major 
Burney, Mr. J. Prinsep' found a sample of black oxide of manganese 
with an earthy fracture and shining black mammillated surface. No- 
thing is known as to the mode of occurrence of this ore. 
Salwin Hill Tracts. 
Wad has been noticed in thin films coating the rocks in the neigh- 
bourhood of Yetagon, a few miles above Yimbaing, a large village on 
the Salwin, about 70 or 80 miles from Maulmain.2 
Taung-ngu District. 
According to Mr. Theobald^ irregular tabular masses and botry- 
oidal nodules of manganese-ore occur in some of the beds of sandstone, 
of the Fossil-wood Group, forming the low range of hills dividing the 
Yayuay and Saing Chaung from the Sit-taung river. An analysis by 
Mr. Tween showed 28% of manganese oxide. 
Amongst some specimens of late rite forwarded in 1906 to the Geo- 
logical Survey Office by Mr. F. J. Branthwaite, Officiating Conservator, 
Tenasserim Circle, Burma, was one collected by Mg. Shein, Deputy 
Ranger, Gwethe Range, Taung-ngu Division, on low land, the exact 
locahty not being specified. This particular specimen cannot be regard- 
ed as a true laterite, but rather as sand or sandstone cemented by oxide 
of manganese. In places where the sand is not cemented by manganese 
oxide the grains are held together by interstitial clayey matter. 
Tavoy District. 
Captain J. Low 4 says that ' manganese exists in considerable quan- 
tities ' in this area, the exact locality not being clearly stated ; but it is
