apparent size of tlie eye and add to its lustre and beauty. In India at least, however, no 
discrimination seems to be made between the sulphide of antimony and ordinary galena, 
which goes also by the name of soormah. 
Gold. —Though of slight economic importance, gold occurs in most parts of Burrnab, 
but is very little worked within British territory, which I attribute to the higher and more 
certain remuneration there obtainable for agricultural or other labor ; and gold working is, 
therefore, pursued mainly in bad seasons, or as an exceptional means of industry taken up 
merely now and again. 
I am not aware of platina having been discovered in British Bunuah, hut as it is known 
in Upper Burmah under the name of Shwaybeen (white gold), it probably, I think, will he 
found in Pegu also, hut perhaps in too fine a state of division to he independently separated. 
In Volume III of the Gleanings of Science a very interesting analysis of a platina 
‘button’ from Ava is given by J. Prinsep, which I here transcribe in proof of the actual 
occurrence of the metal, which might also be doubted:— 
Platina ... 
... 25 
Gold ... 
... 5 
Iridium and osmium 
... 40 
Iron 
... 10 
Arsenic and lead ... 
... 20 
100 
The sole use the metal is put to is as an alloy, the only form of course in which the 
Burmese are capable of manipulating it. The proportion of the metals iridium and osmium 
is remarkable; and additional samples from Bamo are much wanted for analysis, hut such 
are scarcely procurable save on the spot. 
An impure earthy cohalt containing manganese was many years since procured by my¬ 
self near Henzai, but I could learn no particulars beyond the above rather vague one of 
locality. It was a nodular mass of a black color enveloped in white clay, not more than an 
ounce in weight altogether. 
The above remarks are all that I need offer on the subject, my intention being solely 
to point out in a brief manner what previous observers have recorded on the subject of the 
metalliferous wealth of Burmah.
