on the subject by Sir T. Dick Lauder, Bart. FRSE. in which he states, on the authority of a friend employed for many years in the trade between China and India, “ that the substance analyzed by Dr. Fyfe is not tutenag, but white copper, the properties of which are totally different; " and he then proceeds as follows:

The white copper is used by the Chinese themselves, who are so jealous of permitting other nations to have it, that its exportation is contraband. In defiance of this, however, considerable quantities of it are smuggled out of the country, and introduced into India, where it is : considered as a great present to the Hindoos, &c. who make domestic vessels of it. The tutenag, on the contrary, is an article of very extensive commerce between China and India, and my friend informs me, that it is sent from China in elabs, of which he has had occasion to buy and sell many thousands. The slabs are about eight or nine inches long, by about five and a half wide, and about five-eighths thick. Its colour is greyish; and it is not malleable, but so brittle that it is even necessary to use considerable caution in putting it on ship-board, to prevent its being broken by one piece striking against another. The fracture has a glittering lustre, and somewhat resembles the appear., ance exhibited by that of bad iron; but the crystallization (if such a term may be employed) is larger. It does not ring, but emits a heavy clattering sound. It is employed by the natives of India as an alloy for copper, to make brass for their domestic utensils.”

REMARKS

First Month.-1. Cloudy. 2. A gentle thaw with some rain. 3. Fine. 4. Cloudy. 5. Rainy. 6–8. Fine. 9. Hoar frost: fine. 10. Cloudy. 11. Fine: afternoon overcast. 12. Bleak. 13. Some snow this morning. 14. Fine. 15. In a heavy snow which commenced this morning, a flock of some hundreds of wild geese passed over us about ll, a. m. steering their course to the east. The snow fell to about four inches depth on the level. 16. Some snow at 10, p. m. 17. Cloudy. 18-20, Much rime on the trees; which, being rather loosely attached, a part fell as it collected, forming' a regular snow shower under the trees: the latter nevertheless retained at length a sufficient quantity of the icy foliage to enable them to cast a full shadow on the ground as in summer, which had altogether a singular appearance. 21. Fine. 22-24. Cloudy. 25. It began to snow at three, p. m. and the fall continuing through all the night, covered the ground to five or six inches on the level. 26. Cloudy. 27. Some hail at nine, a. m. followed by rain, which continued till near four, p. m. 28. Rain. 29–31. Cloudy. During the intense cold of the month, much ice accumulated in the Thames, the navigation of which was for some considerable time suspended for the smaller vessels. The feathered tribes exhibited in various ways the appearance of distress usual with them on such occasions by changing their quarters, and seeking food nearer than usual to the houses and villages.

ARTICLE I.
Description of a new Mineral. By Mr. A. Levy, MA. of the

University of Paris.
(To the Editor of the Annals of Philosophy.)
SIR,

Great Russell-street, Bloomsbury, March 3, 1823.
I SHALL again beg the favour of your inserting in the Annals
of Philosophy the crystallographical description of a mineral
which I cannot refer to any substance whose primary form has
been determined hitherto. It occurs in small brilliant yellowish-
brown crystals, with adularia and lamellary crichtonite, and
comes from Dauphiny. On account of its colour, accompani-
ment, and locality, it has been classed with sphene; but as it
will appear from what follows, it differs essentially from this last
substance. Its hardness is much less than that of sphene; it
cleaves very easily in one direction, and the face of cleavage is
perfectly brilliant. The primary
form is au oblique rhombic prism,

Fig. 1.
fig. 1, in which the incidence of
the two lateral planes m, m, is
96° 10', that of the base p on one
of the lateral planes 99° 40', and
the ratio between one side of the
base and one of the lateral edges 9
nearly that of 10 to 7. The pri-
mary form of sphene is also an
oblique rhombic prism, but its
dimensions are

different. The hot foscoord
incidence of the two lateral
