U r 2 Queries concerning Amber* 
Oil be found, and in fufficient Quantity, our 
next Enquiry will be concerning the Acid 
Salt: as to which, are not the Chemifts pret> 
ty generally agreed, in fuppofing, that what 
they call a Vague Acid (whereby they mean, 
' > if 
covered with Clay. This Method fupplies the want of Can¬ 
dies in their Houfes. Three or roar of thefe Canes will alfo 
boil Water in a Pot, and they drefs their Victuals with it. 
The Flame may be blowed out like that of a Lamp, but 
Otherwise if continues burning; it fmells fomewhat fulphure- 
ous, or rather like Naptha, but very little offeniive. The 
Ground is dry and iiony, and the more ftony the Ground 
the ftronger and clearer the Flame. Near this Place they 
dig Brimltone, and here are alfo Naptha Springs. But the 
chief Place for Naptha is S-wieten Ifland, a fmall Tra£t of 
Land on the Weftern Coaft of the Cafpian Sea, and uninhabit¬ 
ed, except at fuch Seafons as they fetch Naptha front thence : 
which th ePerJians load in their wretched Embarkations with¬ 
out Barrels or any other Veflels, fo that lometimes you fee 
the Sea covered with it for Leagues together. The Springs 
boil up higheft in thick and heavy Weather, and the Naptha 
fometimes takes Fire on the Surface, and runs lighted or 
burning into the Sea in great Quantities, and to great Dif- 
tances. In clear Weather it does not bubble up above two or 
three Feet. People make Cifterns near the Springs, into which 
they convey what overflows by Troughs, taking oft’the Nap¬ 
tha from the Surface, under which there is a Mixture of 
Water or home heavier Fluid. The greateft Part is of a 
dark grey Colour, very unpleafant to the Smell, but ufed in 
Lamps by the poorer Sort. - There are alfo Springs of black 
Naptha , which is thick, and on Diftilladon grows not clear 
but yellow ; but the mod valuable is the white Naptha, which 
is naturally clear and yellowilh, and bears a great Price. 
The Ruffians drink it as a Cordial, but it does not intoxi¬ 
cate : it is ufed alfo for Pains or Aches, and is carried into 
India as a great Rarity, where they make with it the moll 
beautiful and lading Japan that has ever yet been known. 
What the Indians call the Everlafting Fire, lies about ten 
Englifh Miles, N. E. by E. from the City of Baku , on dry 
rocky Ground. There are feveral ancient Temples, built with 
Stone, fuppofsd to have been all dedicated to F ire; moft of them
