bundles of rice-ftraw and pieces of wood placed in a crofs 

 direftion ; but fuch accidents often happen, particularly in 

 the time of violent fiornis. ■ As they are incapable of freeing 

 the pits from water during heavy rains, they are prevented 

 from working, and mull I'ufpend their labour till the weather 

 becotnes dry. The moft produdlive diamond mines are at 

 Ambauwang, beyond Molucco, in the diftrift of Banjer- 

 maffing, and at Landac and Pontiana. Befides thefe mines, 

 which lie among the mountains, diamonds are fought for 

 alfo on the banks of \arious rivers ; but thofe who follow this 

 occupation have fo little fuccefs, that ten or twelve men will 

 dig and fearch fometimes a whole month before they find 

 diamonds to the value of twenty Spanifh rials. 



In regard to the gold mines, the ignorance of the natives 

 refpecting every thing that relates to mining is fo great, that 

 little advantage is derived from them, though they are fup- 

 pofed to be very rich. In Banjermaffing the gold is- found 

 at the depth of about three fathoms ; the veins properly fo 

 called are of a reddiili kind of marl. At Landac the ore is 

 found at the depth of about ten feet, and the workmen muft 

 dig till they come to a cruft which has almoll the appear- 

 ance of rotten wood. Until this vein, which is called the 

 covering of the mine, be found, there are no hopes of meet- 

 ing with gold.

 Means of Ether. Bj> C. Chaptal. 



J. IIIS method of preparing all kinds of animals for ca- 

 binets Is exceedingly fimple, and fo certain in its efFecl that 

 C. Chaptal never found it to fail in a fingle inftance. It is 

 as follows : — The matter contained in the bowels of the ani- 

 mal muft be evacuated, either by gradually preliing the body 

 towards the ret'^lum, or by inje6ling fome liquid which may 

 remove every thing that ftands in its way. After this opera-' 

 tion, the end of the re£lum is to be tied with a thread, and 

 ether to be InjcAed, with a proper iiulrument, into the body
