The public attention was particularly excited towards this 

 inftrument by the experiments of Dr. Clarke, who fuppofed 

 that by its means, and the employment of the gafeous com- 

 pound above-mentioned, he had fucceeded in reducing fome 

 of the moft refraftory metallic oxyds and ores. The accu- 

 racy of many of Dr. C.'s refults has indeed been fince 

 called in queftion ; but they neverthelefs demonftrate the

angle formed between the MilTouri and Arkanfaw, and pur- 

 fues a courfe to the S.W. for fome dillance, then turning 

 fouthward for 70 or 80 miles, enters the ftate of Louifiana, 

 and afterwards, at a (hort diftance, crofles the N.E. line of 

 Baftrop's grant, purfues a S.W. courfe, and then refumes 

 its direftion to the fouthward, and after running about 60 

 miles enters Ouachitta, above the well point of the ifland 

 of Sicily. The BcKuf, from its fourcc in the Arkanfaw 

 lake to the boundary of the ftate of Louifiana, is about 

 120 miles, and from thence to its mouth nearly the faiVie

BLUFF, a term ufed in N.W. America to denote a 

 particular traft of land. The alluvion of the rivers W. of 

 the AUeghanies is confiderably lower than the furrounding the ordinary preffure of the atmofphere, with due allowance 



of its windings. It is navigable as far as Prairie Mcr Rouge. 

 A ftrong brake of cane ftirts the Boeuf nearly along Us 

 whole courfe, through the ftate of Louifiana. Much land 

 near its banks might be cultivated, but is moftly fubjeft lo 

 cafual inundation.

 of the rivers ; that of the MifTouri is from 2 to 6 or 8 miles 

 in breadth, and is for the moft part from 150 to 300 feet 

 below the general level of the country. The afcent from 

 this valley into the country is precipitous, and is called 

 "the bluff';" and may confift of rock or clay. Be- 

 twixt thefe bluffs, the river runs in a very crooked chan- 

 nel, and is perpetually changing its bed, and the permanent 

 beds are called the bluffs.

for its variable denfity, water does not boil till it is heated 

 to 212° Fahrenheit. However fir George Shuckburgh 

 found, that when the barometer was at 26 inches, water 

 boiled at lefs than 205°; but when it was at 31 inches it 

 required before it would boil a heat of nearly 214°. Under 

 the common preffure of the atmofphere, ether boils at 98"; 

 alcohol at 176°; water at 212°; nitric acid at 248°; ful- 

 phuric acid at 546°; phofphorus at 554" ; and mercury and 

 linfeed-oil at 600°. From the experiments of Dr. Black 

 upon feveral liquids in vacuo, it appears that, in general, 

 they all boiled with about 140 degrees of heat lefs than 

 when fuftaining the weight of the atmofphere. Vitriohc 

 ether, if the preffure of the atmofphere be removed, will 

 boil when 52 degrees below the cold fufficient for freezing
