nearly the whole northern hemisphere, its teeth or bones hav- 
ing been found on both sides of North America, in Siberia, 
in England, Scotland, Italy, and other European countries.

parts of England, belong toa smaller species than that which 
furnished these tusks. The Edi inburgh Museum is indebted 
for these valuable relics, to Lord Melville, who has never been 
unmindful of its interests, when his official station enabled him 
to do it a service.—Scotsman, Nov. 14.

26. Two kinds of Sulphate of Manganese—When black ox- 
ide of manganese is treated with sulphuric acid (as in prepa- 
ring oxygen gas) and the mother water is evaporated, two 
kinds of sulphates are obtained, distinct in their physical as 
well as chemical characters. One of these sulphates crys- 
tallizes in long prisms with four faces, perfectly white, trans- 
parent, and truncated obliquely at their extremities ;—the 
other is in the form of rhomboids and of a rose col Th 
first contains a greater proportion of oxide than the sect ond, 
and is ¢ eiaeuet ok water 28, pe acid 28.66, and ox- 
ide of manganese 43.34. The second is formed of water 
44, of sulphuric acid 32, oxide of manganese 24. In the 
latter, the sub. carb. of potash produces no change. In the 
first it gives rise to a precipitate which appears to be a car- 
bonated oxide of manganese, and which speedily becomes 
brown by the action of the- air—Ferussac’s Bulletin, Sept. 
27. Preparation of Hydriodic Acid; by M. W. Braxpes.— 
Dissolve 60 grains of iodine in a sufficient quantity of alcohol, 
and add to it drop by drop, four ounces of water, in a 
has been stirred an ounce of starch finely pulverised. 
the ioduret of starch has subsided, decant a portion of the 
supernatant fluid: Into the remainder, pass a current of sul- 
phuretted hydrogen; this gas soon produces an orange yellow 
color, occasioned by the formation of See of iodine—the 
color afterwards becomes a pure yellow, and finally disap- 
pears entirely, the starch again becoming white. The liquid
