and other arrangements used for dress-
To Roger Arnold, of Chigwell,
AN exhibition, called walking on
The Patentee proposes to introduce the substance called pumice-stone, as a substitute for teasals or wire-cards, in the dressing, smoothing and polish* ing operations of the woollen manufacture. His organization of the improvement consists in a box or case of wood, about sixteen inches in length, four in width, and two deep, on which pieces of pumice-stone are fastened by glue or water proof cement. He renders this arrangement of the material used, level on its upper surface or working face, by rasping, and allows the piece to project above the sides of the tray about half an inch.
These sets of stones thus prepared, are attached to the cylinder, gignrill Monthly Mag. No. 357.
slower by the proper compensating quantity.
To William Kendrick, of Birmingham, for a Combination of Apparatus for Extracting tanning matter from Bark.
The patentee exposes the fresh or waste oak bark, or other material from which he is to obtain the tanning matter, to the action of steam, or of water heated considerably above the boiling point. His apparatus consists of a boiler capable of generating them at an elasticity, that its pressure shall be not less than from eight to twelve pounds upon the square inch; and from this boiler or steam vessel the steam is conveyed into a vessel containing the bark or substance from which the tanning matter is to be extracted. The steam
from the sleani-condncting'-pipe' is equally diffused in the vessel of bark, by a pipe which reaches nearly to the bottom of the vessel, and pierced with small holes in every part of its length. Observations. In this patent, (which we have no doubt is effectual as toils general object) there are gross and striking incongruities, which it is the responsible duty of a reporter to notice in the way of caution to others. The title of the patent is for an apparatus, for extracting, &c, the specification explains no apparatus, but gives a general account of a method or process, and in the description, of which there is not precision enough to enable an inexperienced person to effect it without a course of experiments of his own.
VARIETIES, LITERARY AND PHILOSOPHICAL,
Including Notices of Works in Hand, Domestic and Foreign.
IT is a fact interesting to science and important to (he progress of aerostation, that the Balloon which ascended from the Green Park, on the day of the Coronation, was filled with ordinary coal-gas, or carburet ted hydrogen, instead of gas prepared from sulphuric acid and zinc, or iron filings, by the usual tedious and expensive process. A pipe was laid on to the main which supplies the street lamps, and the balloon was filled without solicitude in a shorter time than the same operation was ever performed before, and at the expence of £5. Taking the gas at .555 and the diameter at 32 feet, the power of ascension exceeded 7 cwt. Of course the machine acted well, and the ascent was one of the most beautiful ever beheld since the first ascent of Lunardi, in 1785. The varied currents of air in the atmosphere were strikingly exemplified. The wind was nearly east; but, at a certain height/^ the balloon was wafted northward, theft,' • eastward; and it fell at the distance of only thirteen miles,'after making traverses of nearly fifty miles in forty-five minutes.

The title of the proposed volume is "The Proximate Causes of Material Phenomena,'and the true principles of universal Causation considered and illustrated."
A Dictionary of the Chines* L;mgaage is now publishing at Macao, to consist of three parts; first. Chinese and English, arranged according to the Radicals; next, EnglishaudChino.se; and lastly, Chinese and English, arranged Alphabetically. Dr. R.morriSon, the author of the above Work, has directed bis attention to the collection of materials for it during (he last thirteen years. The Honourable East India Company has generously undertaken the whole exjience of printing and paper for an edition of seven hundred and fifty copies. The Chinese language, whether viewed in itself, its f>eculiar structure, or with respect to its antiquity, it having been for nearly 4"V0 years the language of so large a portion of the human species, and it still being the written medium, in private and in public life, in literature, in arts, and in government, of the most extensive empire on earth, seems to deserve the attention of every inquisitive and curious mind.

Mr. Hewick, the celebrated engraver on wood, has been for some time |»ast engaged in preparing for the press, a Supplement to his work on British Birds.

The third volume of Montagu's Ornithological Dictionary, published in 1813, contains thirty birds which were not known either as permanent inhabitants or temporary visitants of this kingdom, eight years previous to that period, making in all ninety-four species, or strongly marked varieties, of which no very accurate lepresen tat ions are to be met with, except a few scattered through the Linmean Transactions and Sowerby's Miscellany, or included in the first number of Mr. Selby's splendid publication. Of these, Mr. Bewick has already delineated thirty-two with that accuracy of outline, truth to natural habit, and delicacy of execution, which render all his works so highly interesting to the naturalist.

The misguided Society, of whose pernicious and anti-social designs we nave duly apprized our readers, has, at length, become the proper object of a criminal prosecution, by the indictment of a Grand Jury. In the mean time, we observe, with deep concern, that it is pursuing its inquisitorial practices against the press in various parts of the country where less caution and less public spirit prevail than in London. We trust, however, that true-born Englishmen will every where be found to do their duty in defeating its base practices.
The Rev. Edw. Chichester will soon publish a professional work, in three octavo volumes, entitled, Deism compared with Christianity.

The Royal Society of Literature offer premiums of one hundred, fifty,and twenty-five guineas respectively, for the best View of the Age of Homer, the best Poem on Dartmoor, and the best Essay on the Greek Language.

Mr. Nicholson's popular Elements of Pure and Mixed Mathematics have been delayed by unavoidable circumstances, but will appear in the course of the autumn. The want of such a supplement to the study of Arithmetic is proved by the anxious demands which have followed its first announcements.
Mr. John Frank Newton has in the press a classical work on the Banishment of Ovid, by the Emperor Augustus, under the title of " the Three Enigmas."
Various lives of Napoleon are announced, but as their object is either to profit by public sympathy, or to pander to the prejudices of power, it is to be hoped that the public will reserve themselves for his own Memoirs, against the transmission of which, and the free publication, no objection can now be decently opposed.

A writer on the subject of vaccinating dogs, for the prevention of the distemper, states, that James Dearden, Esq. of the Orchard, Rochdale, was unable for several years to rear a single dog; whether he kept them at home, or sent them out to quarters, they all died of the distemper; but about four or five years ago he began to have them vaccinated, and since that time not one dog has suffered from it. The operation has been performed when the dogs were from six weeks to two months old, and the matter has always been inserted on the inner surface of the ear, in a part as free from hair as possible.

The quarries of marble whence the blocks are taken for the construction of the Plymouth break-water are situated at Oreston, on the eastern shore of Catwater. They consist of one vast mass of compact close-grained marble; seams of clay, however, are interposed through the rock, in which there are also large cavities, some empty, and others partially filled with clay. In one of these caverns in the solid rock, fifteen feet wide, forty-five feet long, and twelve feet deep, nearly filled with compact clay, were found imbedded fossil bones belonging to the RhinoceRos, and portions of the skeletons of three different animals, all of them in the most perfect state of preservation. The part of the cavity in which these bones were found was seventy feet below the surface of the solid rock, sixty feet horizontally from the edge of the cliff, and one hundred and sixty feet from the original edge by the side of the Catwater. Every side of the cave was solid rock: the inside had no incrustation of stalactite, nor was there any external communication through the rock in which it was imbedded, nor any appearance of an opening from above, being inclosed by infiltration.
A short time since, as David Virtue, mason, at Auchtertool, a village four miles from Kirkaldy, in Scotland, was dressing a barley mill-stone from a large block, after cutting away a part,
