AURORA BOREALIS.-The Aurora on the evening of the 12th, from 5 till after 10 o'clock, was remarkably brilliant; the coruscations, thoughfew, were vivid, and of a deeply red colour. Again, on the evening of the 15th, about 7, when it was even more splendid, the coruscations which were white, and also more numerous, vivid, and extensive, and apparently based upon a deep crimson ground.

To THOMAS GAUNTLEY, of the town and county of Nottingham, mechanic, for his invention of certain improvements in machinery for making lace and other fabrics, commonly called warp machinery. August, 1836.]

[Sealed 15th

THESE improvements in warp machinery employed for making lace and other fabrics, consist in the adaptation to that kind of machinery of a series of thin blades, which are denominated thread-carriers, being for the purpose of lapping the threads upon the bearded needles, and thereby superseding the necessity of the guides passing between and over the needles, as in the ordinary modes of working that sort of machinery.

In the accompanying drawings, see Plate IX., figs. 1, and 2, represent, in two positions, a series of these 2 c

thin blades set in a lead in the way, in which they would be prepared to be mounted in the machine. Fig. 3, is a section taken transversely through a complete machine, in which these thread-carriers are seen at A, mounted upon a longitudinal bar B; and fig. 4, is an elevation of the back part of the same machine.

In this, and the preceding figure, the thread-carriers, and the new parts by which they are worked, are marked with capital letters; the other, or old parts of the machinery, are shown in outlines only, and are marked by small letters; the several letters of reference indicating the same parts throughout all the figures.

The bearded needles are shown at a, set in leads, and mounted in a horizontal series upon the needle bar b, as usual; c, c, c, are three series of guides fixed upon their several bars, which carry and conduct the threads from the warp beams d, d, d. The sinkers e, mounted in leads, in the ordinary way, are affixed to the sinker bar f, the centres of which I prefer to place below the needle bar. The presser bar g, is, as usual, above the needles. All these parts are constructed nearly in the same way, and operate in a similar manner to the mechanism of an ordinary warp frame when driven by rotary power, excepting the parts supporting the guides (technically called the machine); which parts are, by me, merely slidden in and out by a cam i, acting against a rocking lever j, j, affixed to a shaft k; to this the bent levers l, l, are attached, which work the guide frame ; the up and down vibratory movements of the guides being, by the adaptation of my improvements, dispensed with.

The thread-carriers A, are made to rise and fall, through the agency of arms or levers c, extending forward from a longitudinal bar, called the central rocking
