mean to retain such part of those specimens as they may judge necessary, making a reasonable allowance for the same. No candidates shall be present at any meetings of the Society or committees, or admitted at the Society's rooms, after they have delivered in their claims, until such claims are adjudged, unless summoned by the committee. N. B. The Society farther invite the communications of scientific and practical men upon any of the subjects for which premiums are offered, although their experiments may have been conducted upon a smaller scale than the terms of each require, as they may afford ground for more extensive application, and thus materially forward the views of the Society, and contribute to the advantage of the public. Such communications to be made by letter, addressed to the Society, and directed to Mr. CHARLES TAYLOR, the Secretary, at the Society of Arts, Adelphi, London. The models required by the Society should be upon the scale of one inch to a foot. The Winchester bushel is the measure referred to for grain; and, as the acres of different districts vary in extent, it is necessary to observe, that the Society mean Statute Acres of five and a half yards to the rod or pole, when acres are mentioned in their list of premiums; and they request that all communications to them may be made agreeably thereto. The Society desire that the Papers on different subjects sent to them may be full, clear, explicit, fit for publication, and rather in the form of Essays than of Letters; and where descriptive Drawings can be conveniently sent, with the Models and Machines laid before the Society, is is recommended to be done. Presents to the Society of Books for their Library will be thankfully received. To persons inclined to leave a sum of money to this Society by will, the following form is offered for that purpose. Item. I give and bequeath to A. B. and C. D. the sum of upon condition, and to the intent that they, or one of them, do pay the same to the Collector for the time being, of a Society in London, who now call themselves the Society for the Encouragement of Arts, Manufactures, and Commerce; which said sum of I will and desire may be paid out of my personal estate, and applied towards the carrying on N.B. The Society for the Encouragement of Arts, &c. considering that it would be beneficial to the Commerce of the United Kingdom, to bring the British Marbles into more general use, and that the most effectual method of accomplishing their object, would be, for the present, to make them more generally known in the capital, have come to the following resolutions :-- Resolved, That specimens of British Marbles be exposed in the Society's Rooms at the Adelphi for the inspection of the Public, under the following regulations : 1st, That all specimens be exact to a given size, viz. eight inches high, six inches broad, one inch thick, and polished on one face, 2d, That a book be kept containing the number of each specimen, and describing the situa tion of the quarry, the name of the parish where situated, the distance of the quarry from a beaten road, and the distance of that road from water-carriage, with the name of the donor and proprietor. Any remarks on the qualities of the marbles, or on the lime produced from them, will be gratefully received and preserved by the Society, as materials for future inquiries. Resolved,That as the exertions of the Society can only be beneficial to the public, inas - much as their views are seconded by the public, the Society request, that all persons proprietors of marble quarries will favour then with a specimen of the marble, worked to the exact size above mentioned, with the description of the quarry as above, that the same may be entered in the book to be preserved for the use of the public.

VARIETIES, LITERARY AND PHILOSOPHICAL, Authentic Communications for this Article will always be thankfully received. A Plan of a Telegraphic Establishment edition of the Portical Wolks, will be for Domestic and Commercial Purpofes having been fuggefted fome time fince to Mr. BOAZ, the ingenious patentee of a Day and Night Telegraph (vide vol.13,page 250), that gentleman has lately fubmitted propofals for a local experiment to the inhabitants of Liverpool. A line of Telegraphs is in confequence about to be eftablished from Liverpool to Holyhead, for the purpose of announcing the arrival of thips bound for Liverpool, and of procuring pilots. Another line has been fuggefted, from Liverpool to Hull, through Manchester and Leeds; and another from Liverpool to London, through Chefter and Birmingham. These several lines would not coft more than 15,000l. and, on a moderate calculation of the meffages which would be fent through them, at the rate of a guinea per eight words, per 100 miles, there is no doubt, but the eftablishment would, on the average, net an annual profit of 2 or 300 per cent. The perfon with whom this plan originated, hoped to fee it executed by government, and a telegraphic eftablishment extended from the metropolis to every market town in the kingdom; but it is probable that its utility and profit muft a first be demonftrated by the experiment of private individuals, before the nation at large can be made to participate in the advantages of fo wonderful a fyftem of conveying intelligence-a fyftem which would confer a fort of ubiquity on thofe who might choofe to avail themselves of it, and which would render the whole of this bufy and extended nation like one concentrated metropolis.

Dr. MOODIE, of Bath, has used, with the greatest succefs, the aqua kali puri (olim lixivium faponarium), in cafe of a woman who had been bitten by a viper, and who was apparently in a dying condition. A tea-fpoonful was at first adminiftered in water, every three or four hours, and afterwards every fix hours: the was relieved immediately after the first dose, and in four days was perfectly reftored to health. The Doctor further obferves, that when perfons are bitten by animals whofe venom is highly deleterious, the progrefs of the difoider may be stopped, and the perfon faved, by the fpeedy adminiftration of the lixivium faponarium. Hence alfo, if any of the ftrong mineral acids fhould fall on any part of the body, the immediate application of this fubftance will prevent them from doing further mischief. Or, if a per fon fhould accidentally fwallow any of the mineral acids, or hydrargyrus muriatus, or any other corroding falt, which an alkali will decompofe, a fpeedy exhibition of a folution of the alkaline filts, in proper dofes, affords the most likely means of relief, and of preventing fatal effects.

The Secretary of the Vaccine Pock Inflitution, Broad-freet, Golden-fquare, bas addreffed the following Letter to the Editor of the Monthly Magazine. The public mind being of late much difturbed in confequence of fucceffive reports during the whole of the last year, and especially of late, by publications of cafes esteemed to be inftances of the Small. pox two or three years fubfequently to the Cow-pock; the Medical Eftablishment of this Inftitution have thought it their duty, what ever may be their own opinions, not to be inactive and filent. Accordingly I am directed to ftate, that in the laft fortnight a number of fubjects who had undergone vaccination in the year 1800, (the first year of the new practice at any profeffed infiitution) have been fubmitted to the teft or counter-proof variolation, in circumftances the most favourable for exciting the Small-pox. Befides thefe trials, additional ones have been inftituted on subjects who were vaccinated in Dr. Pearlons and Mr. Keate's early practice in 1799. Further: reports have been already received at the Inftitution from several provincial correfpondents, who were witne fles 10 whole parishes of fubjects vaccinated under Dr. Pear fon's infpection, or with matter furnished by himself early in the year 1799.* A It may be very important information to affirm, that the matter now used at this Inftitution was that originally taken, in January and February, 1799, by one of the phyficians, from cows in Mary-le-bone-fields and Gray's I very brief, but it is prefumed conclufive, Statement of Evidence collected from these fources on the question with which fome perfons have agitated the minds of fon any fafamilies is intended to be laid before the pubis apprehended, will be the moft proper return lic in a week or ten days. This statement, it addreffed his pamphlet To the Directors of to the refpectable author,† who has lately the Vaccine Infiitution,' very juftly conceiving that the point at iffue is within the power of this Inftitution, if they will give directions for a number of perfons to be inoculated with Small-pox matter, or expofed ftrongly to infection, who were vaccinated early in the practice.' As no other profeffed vaccine inftitution but this has been eftablished long enough to answer the demand, it has been determined to comply " of The ingenious Mr. CUTHBERTSON gives the following as the refult of many experiments in Ga vanifm: (1) Charcoal inch in length; (2) iron wire, of an inch was deflagrated and ignited for about one in diameter, was melted into a ball inch in diameter, was melted into a ball, to an inch in diameter; (3) platina wire, in diameter, was ignited; (5) brais, 16 inch in diameter; (4) bais wire, 1 inch inch diameter, was red hot at the extremity; (6) iron wire, inch in diameter, was red hot for 16 inches in length; (7) iron wire, 12 inches, deflagrated and melted into a ball; (8) iron wire, fix inches in length was deflagrated; (9) iron wire, eight inches in length was ignited. Two troughs, each containing 30 pair of plates, fix inches fquare, were ufed for the first feven experiments; and one of thefe troughs only for the last two experiments. The four last experiments, Mr. Cuthbertson thinks, go to prove, that double quantities of Galvanic fluid burn double lengths of wire, and not the square, as electrical charges do. A volume of Sermons on various fub. jects, by the Rev. C. P. LAYARD, D.D. F. R. S. F. A. S. late Dean of Bristol, is in the prefs. Mr. J. BRAMAH has invented a new jib. The peculiar conftruction confifts in perforating the axis or pillar of the crane, inn-lane, with the addition, about three years ago, of matter from the Milanefe by Dr. Tacco But it does not appear that this extenfive fucceflion has at all altered the properties, nor that there is any difference of properties amongst thefe different fources of matter. The experience of this Inftitution does not juftify the conclufions, that the failure of the Cow Pock in preventing the Small Pox depends in general upon the felection of matter on a particular day. + See Mr. Goldfon's Cafes of Small-pox fubfequent to Vaccination. and and in conducting the rope through this Mfrs HARMAN and DEARN, of Rotherhithe, have invented an appar tus for filtering water, which will obviate the inconvenie ces of the filtering ftone. The new apparatus confifts of a stone-ware veffel, perforated with holes, upon which coarse gravel is laid, and upon that a ftratum of fine gravel, and laftly fine fand, Upon the top of the fand is laid a perforated ad loaded board or plate of earthen ware, to prevent the fand from being disturbed when the water is poured in. The fineness and depth of the filiceous land will regulate the perfection and expedition of the procefs, and the delicacy of the veffels and fand may be in fured by changing the latter from time to time; for example, once in a fortnight or three weeks.

BRUGNATELLI has obferved that when nitric acid is made to act upon paper, a large quantity of fuberie acid, mixed with oxalic acid, is obtained, which proves that FOURCROY was right in placing cork among the immediate principles of vegetables. A piece of amber weighing 13 pounds, 7 ounces, 9 fcruples; and measuring 3183 cubic inches, has lately been found at Schlapaken, in Germany, which is the largest mass of amber hitherto found. Its colour is a pale yellow, interfected with feveral lines. Its estimated value is 40,000 dollars. DEMMENIE has noticed that the folution of copal may easily be effected by expofing it to the vapours of alcohol, or oil of turpentine. For that purpose an alembic may be filled one-fourth with either of thefe fluids, and fome pieces of copal fuffered to be fufpended by threads in it, over the furface of the fluid. After having made the alcohol, or oil of turpentine, boil, the copal becomes liquified, and is dif folved. This is the belt method of preparing copal varnish. The following is a new method of preparing nitric ether, by BRUGNATELLI.— Introduce into a tubulated retort, one ounce of fugar, and pour over it two ounces of highly concentrated alcohol. Adapt to the retort a capacious receiver, furrounded with cloth dipt in water, and fecure the junctures of the veffels, by furrounding them with flips of paper only; then pour through the tubulare of the retort 30 ounces of concentrated nitrous acid; a violent action takes place, the fugar is diffolved; the alcohol is converted into ether, and paffes over into the receiver; its quantity is nearly equal to the alcohol employed. The oliferous China Radish, the raphanus Chinenfis annuus oliferus, is much culti vated in Piedmont and the Milanefe. From 31⁄2 ounces of feed, a farmer, named Grandi, obtained a produce of 583 pounds, which yielded 200 pounds weight of oil. The Chinese extract from the feed half its weight in oil. It is employed by the Italians for culinary purposes, burns without emitting any (moke, and gives light as clear as common oil. In the Milanefe, the feed is fown in March, the land having been ploughed in autumn, and again before the feed is fown, but not manured. The plan's are to be thinned to the diftance of three or four inches from each other.
