NATIVE BISMUTH.

We are informed by Professor Silliman, that this metal has lately been discovered in the town of Huntington, parish of New Stratford in the state of Connecticut. It is interspersed through a vein of quartz, in brilliant plates; the largest generally not more than an inch in diameter, its surface is sometimes beautifully reticulated. In the same vein are common and magnetic pyrites, galena and other substances indicating a metallic deposit. As yet, the Bismuth is found only in a few spots in the vein, and it is uncertain whether it can be obtained in quantity, the vein however has been but little explored.

ELASTIC MARBLE.

Extract of a letter from William Meade, M. D. to the Editor.

"I informed you sometime ago of a discovery I made of Elastic Marble; since that period, I have obtained some fine specimens, and have ascertained to a certainty, that so far from its elasticity being caused by the loss of its water of crystallization as asserted by Fluvean de Belvue and others, that it is (in this species at least,) precisely the reverse. An accident produced this discovery. I had procured a piece of this marble two feet long and one inch thick, which I was induced from its fine grain and colour, to get polished. When this had been done, and the surface was dried near the fire, I was surprised to find, that it had totally lost its elasticity, and was inclined to attribute it to the change which may have taken place in the arrangement of its particles, by

the action of polishing. Unwilling however to lose so fine a specimen, it occurred to me to wet it with water, and I found its elasticity immediately restored. I have tried the same experiment on other specimens, and I can at any time deprive them of this property by heat, and restore it immediately by plunging them in water."

PROPOSED CLASSIFICATION OF SOME OF THE ORES OF IRON.

The following which was intended as a note to Colonel Gibb's paper on the mass of Iron from Louisiana, we received after that part of our present number was printed off, we therefore now insert it as connected with that communication.

"I should be tempted to alter the nomenclature and classification of these substances, in the following manner.

Genus. IRON.

1st. Species. Native Iron.

1st. Subspecies. The varieties of native Iron containing Nickel which might retain its common

name.

2nd. Subspecies. Native oxydulous Iron which is the Magnetic Iron of Werner and Fer oxydulè of

Hauy.

3d. Subspecies. Native oxydulous chromiferous Iron which is the second subspecies, containing also oxyd of chrome according to Messrs. Silliman and Gilmor.

MINERALOGICAL PREMIUMS.

We feel peculiarly gratified in noticing every effort towards increasing mineralogical knowledge, and in our opinion there is nothing which contributes more towards the accomplishment of this object, than the adjudging to such as are proficients in the science, rewards commensurate with their attainments, and it is therefore with no ordinary degree of pleasure that we announce the following distribution of premiums, offered by Colonel Gibbs and Professor Silliman.

Colonel Gibbs' premium consists of one hundred specimens to be taken from the duplicates in his collection, this premium to continue for five years and to be adjudged to such member of the senior division of the Mineralogical Class in Yale College as his companions of the same division designate by more than one half of the whole number of their votes; the choice is founded upon superiority of attainments in mineralogical knowledge, and upon services rendered to the science by useful discoveries and observations.

1811.

Colonel Gibbs' premium was adjudged to Mr. Solomon Baldwin of Brookfield, Connecticut.

During his attendance on the Lectures, he discovered the beautiful green marble which he is now working in the vicinity of New-Haven.

1812.

This Premium was adjudged to Mr. Elijah Baldwin, Milford, Connecticut.

As a further encouragement to the study of mineralogy, Professor Silliman has added a second premium to the senior and junior divisions of the class. It is a copy of this

Journal for five years from its commencement. To the junior division of the class, he offers as a premium, a free ticket to his future courses of lectures on mineralogy.

These Premiums were adjudged in 1812.-The second Premium in the senior class to Mr. George Bliss of Springfield, Massachusetts.-The first in the junior class to Mr. Elias Cornelius of Somers, New-York.-The second in the same class to Mr. Hiram F. Mather of Haddam, Connecticut.

1813.

Senior Class.

1st. Premium. 100 specimens of foreign Minerals, given by Colonel Gibbs,—adjudged to Mr. Hiram F. Mather, Haddam, Connecticut.

2nd. A A copy of the American Mineralogical Journal, for five years from its commencement,-adjudged to Mr. Elias Cornelius of Somers, New-York.

Junior Class.

1st. Premium. The same,-adjudged to Mr. Joseph H. Dalles, of Charleston, South Carolina.

2nd. A free ticket of the Mineralogical lectures,―adjudged to Mr. Theodore Dwight, Jr. of Hartford, Connecticut.

KIRWAN.

It is with sincere regret we announce the death of this great man, to whom Ireland in particular, and the world in general, owe so much. He may justly be considered as having contributed more during the age in which he lived, than any other individual towards promoting mineralogical science in Great Britain.

We trust we shall, ere long, receive from the hands of some able biographer, a detailed account of the labours of this most useful member of society.
