Between Tsetama, and Kyank Tyan a different kind of limestone (p. 192) 
occurs in practically unlimited quantity. It is remarkable as being an almost 
pure carbonate of lime, there being hardly -any matter in it insoluble in acid, 
and only ti-aces of iron and magnesia. 
Limestone also occurs, although in less abundance, at Than Chaung, Tengbain, 
Alle Chaung, Tsane, and Amherst Island. Doubtless it is to be found on Cheduba 
also. In the Baranga Islands, however, I observed no calcareous rock anywhere. 
Besides true limestone, recent coral, owing to the elevation that the Ramri 
group of islands underwent during the last century (p. 190), occurs in large 
quantity along the coast in many places, where there are rocks that afforded the 
coral animals a secure foundation to build on. Amongst other localities may be 
mentioned the rocky point west of Kyauk Phyu and the similar point at Likmau. 
It will thus be seen that there is an exhaustless supply of lime in the islands 
conveniently placed for export. Mr. Theobald, also, mentions at least one spot 
on the coast of Arrakan to the south of Sandoway where limestone occurs in 
unlimited quantity and in a most favourable position with respect to shipment.‘ 
It is open to consideration -whether the lime of An-akan coidd not compete 
on paying terms in the Calcutta market with the Sylhet lime which is subject 
to the long and tedious river navigation from Chhatak. 
In some places, as at Kyauk Tyan and Amherst Island, there are gypseous 
shales through which crystals of selenite are sparsely 
ijpsxim. disseminated. These are to be found scattered about 
on the surface of the ground, owing to the weathering away of the rock. It 
would bo difficult, however, to obtain more than a few sers of them, and as a 
source of gypsum they are perfectly useless. 
It appears from Dr. Spry’s paper on Kyauk Phyu written in 1841, that salt 
was at that time made there from sea water by solar 
evaporation, and sold by the people to Government at 
7 annas a man.^ The manufacture has, however, been extinct for many years past. 
Limpid rock crystals occur in some of the seams of the chorty rock men¬ 
tioned at p. 192, and are collected sometimes by the 
villagers. But they are too small to be of any 
commercial value. 
In the twelfth volume of the Asiatic Society’s Journal an account is given 
of an alleged discovery of native copper on Round 
Island. The specimens were found in 1843 by a 
Mug who was employed by Captain Williams to 
search for coal. Captain Williams sent them to Mr. Piddington, who pronounced 
them to be “ nodules of native copper, "vvith red and black oxide and silicate 
of copper.®” He also speaks of them as “ rolled native (virgin) copper” “with 
a coating of red oxide and the blue and green carbonates.* ”

the specimens to be an alloy of copper, titanium, mercury, lead, cobalt and iron.
