NOTICES, 
Some time ago was announced the discovery of a whole mam- 
moth in a frozen state on the northern coast of Russia, which has 
been brought to Petersburgh. The bones of an unknown animal 
were lately found in a peat moss in Russia. The creature must 
have been about 12 feet long : the horns were 2J feet long, and l.| 
foot round at the root. From the appearance of this imperfect 
skeleton it seems to have belonged to the URUS or AUROCHS 
mentioned by Caesar in his account of Germany. Anal. Rev.

Variatio?i of the Comfiass. — A correspondent remarks that the 
needle which in this latitude pointed truly to the North in 1657 
and has been inclining to the Westward ever since, at the average 
rate of ten minutes per annum has reached the utmost extent of 
its variation ; has been stationary, and is now receding. If this be 
correct it seems that about 25 degrees is the extent of its varia- 
tion Westward: that it will in about 150 years, again point truly 
to the North; and probably for the next 150 years will incline 
to the East, taking up a period of 500 years in making a 
revolution. Ibid« 
A Steam Engine has been erected at Bristol (England) of 
which the principle is said to be a hollow wheel, whose interior 
is half filled with a fluid metal. The steam is supplied by a com* 
mon boiler and makes no noise whatever, saving half the coals. See, 
Mr. Bakeweli who lectures at the lurry Street Institution, 
proposes the application of gunpowder as an impelling force in 
lieu of steam. A single dram of gunpowder properly applied, 
will rend a piece of metal equal in thickness to a large piece of 
ordnance. The motion might be communicated by a balance 
wheel and crank. Ib . 
Mr. Accum has published a method of making IoDE,the sub- 
stance which at the heat of 158 of (the Centigrade ?) thermometer 
is converted into a violet coloured gas. It was first discovered by 
M. Courtois, and obtained from Kelp. It is not acted on by oxy- 
gen, or charcoal : it combines with the metals and their oxyds, 
forming soluble compounds. It combines also with hydrogen
