tain a fixed alkali. If the tubes be filled with infusion o cabbage, the signs of alkali and acid are very soon observed, from the liquid of z becoming red, and that of c green. If the connection be reversed, the liquids repass to the blue colour, and if the process be continued, that of z becomes green, and c red.

Galvanism, as a source of light and heat.

Batteries of great dimensions, such as contain from 5,000 to 10,000 square inches each, of zinc and copper surface, are capable of furnishing abundance of sensible heat and much light. If the connection between the two ends of the battery be made by a very small wire, such as the fine watch spring wire, the wire becomes red-hot for a considerable length, and if the power of the battery be great, *come. white-hot, and ultimately fused. Let the end of the wires of the battery be each provided with a pair of tweezers, one pair of which being insulated from the hand by covering the surface with dry cloth ; place between each pair of tweezers a small bit of charcoal, made in a close vessel, from box-wood, or lignum vitae. The moment the contact is formed between the bits of charcoal, a vivid light is produced, much more brilliant than that occasioned by burning in oxygen. If the contact be frequently severed by a sort of tremulous motion, the light may be kept up for some time. The foils and small wires of metals are deflagrated by placing them in the current. Let one of the conducting wires be brought in contact with an iron dish, filled with mercury. Let the foil or small wires be attached to the other conducting wire, and be brought in contact with the surface of the mercury, which, constantly presenting a clear surface, is very convenient in these experiments. A very brilliant effect may also be produced, by presenting the foils to the surface of a sheet of tinsel In flaming oils, alcohol, &c. by galvanism, some thin metallic substance, or a small piece of charcoal, should be cowered with the substance to be inflamed. The moment the contact is made, as in deflagrating the metal, the oil takes fire. The galvanic spark, with great facility, fires a mixture of oxygen and hydrogen

gases. A very brilliant discovery has lately been made by Mr. Davy, Professor at

the Royal Institution, and confirmed by others, which consists in the decom;osition of the two fixed alkalies. It is performed by placing a bit of the alkali in the solid state, and a little moistened, upon a plate of platina, connected with one end of the battery, and bringing into contact with it another piece of platina, from the other end of the battery. A portion of black matter is soon formed, in which is found imbedded small metallic globules; which substance is found to be the base of the alkali, and has been deprived of its oxygen by the galvanic agency. These globules are so inflammable, as to decompose water, with a brilliant flash and slight explosion. See Alkali. This discovery will be of great importance to chemistry, and will probably soon make a serious change in its arrangement and nomenclature. GAMBOCE, is a substance obtained from the stalagmites cambogioides, a tree that grows wild in the East Indies; from which it is had by wounding the shoots, It is brought here in large cakes, which are yellow, opaque, and brittle. With water it forms a yellow turbid liquid used in painting. In alcohol it is completely dissolved. If taken internally, it operates violently as a cathartic. GAME. It is a maxim of the common law, that goods of which no person can claim any property belong to the King by his prerogative ; hence those animals ferae naturae, which come under the denomination of game, are styled his Majesty's game ; and that which he has he may grant to another; in consequence of which, another may prescribe to have the same within such a precinct or lordship. And hence originated the right of lords of manors, or others, to the game within their respective liberties. For the reservation of these species of auimals, or the recreation and amusement of persons of fortune, to whom the King has granted the same, and to prevent persons of inferior rank from misemploying their time, the following acts of parliament have been made. The common people are not injured by these restrictions, no right being taken from them which they ever enjoyed; but privileges are granted to those who have certain qualifications therein mentioned, which before rested solely in the King To entitle any one to kill game, he must now take out a cer. tificate, upon which a stamp duty is payable. These certificates are to be dated the day of the month when issued, and shall be in force till the first of Jul following, and no longer; and if any .. of the peace, his deputy, or steward, clerk, &c. issue certificates otherwise than directed, to forfeit 201. 25 Geo. III. sess. 2. No person to destroy game, until he has delivered an account of his name and place of abode to the clerk of the peace, or his deputy, or to the sheriff, or steward, clerk of the county, riding, shire, stewartry, or place where such person shall reside, and annually take out a certificate thereof, which must have a stamp duty of 31. 3s. 25 Geo. III. sess. 2. Any person counterfeiting or forging any seal or stamp directed to be used by this act, with intent to defraud the revenue, or shall utter or sell such counterfeit, on conviction thereof, shall be adjudged a felon, and shall suffer death without benefit of clergy; and all provisions of former acts relative to stamp duties to be in force in executing this act. 25 Geo. III. sess. 2. Every qualified person, shooting at, killing, taking, or shooting, any pheasant, partridge, heath-fowl, or black-game, or any grouse or red game, or any other game, or killing, taking, or destroying any hare, with any greyhound, hound, pointer, spaniel, setting-dog, or other dog, without having obtained such certificate, shall forfeit the sum of 20l. Id. Clerks of the peace, or their deputies, or the sheriff, or stewardclerks, in their respective counties, ridings, shires, stewartries, or places, shall, on or before November 1, 1785, or sooner, if required by the commissioners of his Majesty's stamp duties, transmit to the head office of stamps in London, a correct list, in alphabetical order, of the certificates by them issued between the 25th day of March in the year 1785, and the first of October in the same year; and shall also in every subsequent year, on or before the first of August in each year, make out and transmit to the stamp office in London,correct alphabetical lists of the certificates so granted by them, distinguishing the duties paid on each respective certificate so isused; and on delivery thereof, the receiver-general of the stamp duties shall pay to the clerk of the peace, &c. for the same, one halfpenny a name; and in case of neglect or refusal, or not inserting a full, true and perfect account, he shall forfeit 201. Id. Lists may be inspected at the stamp office for 1s, each search ; (id.) which list shall once, or of. tener, in every year, be inserted in the newspapers in each respective county. If any qualified person, or one having a deputation, shall be found in pursuit of

game, with gun, dog, or net, or other engine for the destruction of game, or taking or killing thereof, and shall be required to show his certificate, by the lord or hady of the manor, or proprietor of the land whereon such person shall be using such gun, &c. or by any duly appointed gamekeeper, or by any qualified or certified person, or by any officer of the stamps, properly authorised by the commissioners, he shall produce his certificate; and if such person shall refuse, upon the production of the certificate of the person requiring the same, to show the certificate granted to him for the like \ purpose ; or in case of not having such certificate to produce, shall refuse to tell his christian and surname, and his place of residence, and the name of the county where his certificate was issued, or shall give in any false or fictitious name, he shall forfeit 50l. 1d. Certificates do not authorize any person to shoot at, kill, take, or destroy, any game, at any time that is prohibited by law, nor give any person a right to shoot at, &c. unless he be duly qualified by law. Id. No certificate obtained under any deputation shall be pleaded or given in evidence, where any person shall shoot at, &c. any game out of the manors or lands for which it was given. The royal family are exempted from takeng out certificates for themselves or their deputies. Id. The duty on these certificates are now, by an act which is at present passing the house, to be had through the collectors of the assessed taxes. The above is the law now in force. Besides having a certificate. each person to kill game inust be qualified by having a certain estate. The last general qualification (to use the words of Dr. Burn, though in fact it is the first of the acts relative to the game ever now put in force,) by estate or degree, to kill game, is 22, 23 Charles II. c. 25. This enacts, that every person not having lands or tenements of the clear yearly value of 100l. or on leases for 99 years, or upwards, of the clear yearly value of 1501, or except the eldest son and heir of an esquire or person of higher degree, or owners of forests, parks, &c. in respect of such fo. rest, park, &c. is not qualified for himself, or any other person, to keep guns, bows. greyhounds, &c. s. 3. This merely states the qualification; the penalties and modes of proceeding are entirely changed by subsequent acts: and first, by 3 Anne, c. 14, which directs that all former acts not thereby repealed and altered continue in force. With respect to offences against the game laws, we shall here enumerate

Game, are deer, hares, pheasants, partridges, moor game, and, by the act now passing, snipes and woodcocks are made game. It is not to be inferred that these statutes actually impower qualified persons to hunt or shoot any where. They cannot enter another man's land in pursuit of game without his leave; but at the same time, if he has not warned the sportsman against coming upon his hand, he will not recover more than 40s. costs in an action of trespass. Sporting seasons. The time for sporting, in the day, is from one hour before sun rising, until one hour after sun setting. 10 George III. c. 19.

M. de Moivre, in a treatise “De Mensura Sortis,” has computed the variety of chances in several cases that occur in gaming, the laws of which may be understood by what follows: Suppose p the number of cases in which an event may happen, and 7 the number of cases wherein it may not happen, both sides have the degree of probability, which is to each other as a to q If two gamesters, A and B, engage on this footing, that, if the cases p happen, A shall win; but if q happen, B shall win, and the stake be a ; the chance of A will be Po. and that of B++ ; Consequently, if they sell the expectancies, they should have that for them respectively If A and B play with a single die, on this condition, that, if A throw two or more aces at eight throws, he shall win: otherwise B shall win; what is the ratio of their chances * Since there is but one case wherein an ace may turn up, and five wherein it may not, let a = 1, and b = 5. And again, since there are eight throws of "re die, let n = 8; and you will have on br—n a b 1, to bri + n a bn—1 : that is, the chance of A will be to that of B, as 663,991 to 10,156,525, or nearly as 2 to 3 A and B are engaged at single quoits, and, after playing some time, A wants 4 of being up, and B 6; but B is so much the better gamester, that his chance against A upon a single throw would be as 3 to 2: what is the ratio of their chances * Since A wants 4, and B 6, the game will be ended at nine throws; therefore raise a-Hb to the ninth power, and it will be a9-H9ao b + 36 a 7 b b-I-84 as 55+ 126 as b1-H126 as b%, to 84 as bo-H.36 a a 67 +6 a bi-H bo' call a 3, and b 2, and you will have the ratio of chances in numbers, viz. 1,759,077 to 194,048.

and, consequently, z = 373-1. The chances therefore, are */ }= 1’ and 1,

respectively. Again, suppose I have two wagers depending, in the first of which I have 3 to 2 the best of the lay, and in the second, 7 to 4, what is the probability I win both wagers ? 1. The probability of winning the first is #. that is, the number of chances I have to win divided by the number of all the chances: the probability of winning the second is or . therefore, multiplying these two fractions together, the product will be #}, which is the probability of winning both wagers. Now, this fraction being subtracted from 1, the remainder is # which is the probability I do not win both wagers: therefore the odds against me are 34 to 21. 2. If I would know what the probability is of winning the first, and losing the second, I argue thus: the probability of winning the first is 3, the probability of losing the second is *r: therefore, multiplying ; by for, the product #3 will be the probability of my winning the first, and losing the second; which being subtracted from 1, there will remain #, which is the probability I do not win the first, and at the same time lose the second. . 3. If I would know what the probability is of winning the second, and at the same time losing the first, I say thus: the probability of winning the second is or ; the probability of losing the first is ; ; therefore, multiplying these two fractions together, the product # is the probability I win the second, and also lose the first. 4. If I would know what the probability is of of both wagers, I say, the probability of losing the first is #, and the probability of losing the second # ; therefore, the probability of losing them both is # which being subtracted from 1, there remains #; there

fore, the odds of losing both wagers is 47 to 8. This way of reasoning is applicable to the happening or failing of any events that may fall under consideration. Thus, if I would know what the probability is of missing an ace four times together with a die, this I consider as the failing of four different events. Now the probability of missing the first is #, the second is also #, the third #, and the fourth ; ; therefore the probability of missing it four times together is # x : x # × 3 = ***, which being subtracted from 1, there will remain 1% for the probability of throwing it once or of. tener in four times; therefore the odds of throwing an ace in four times, is 671 to 625. But if the flinging of an ace was undertaken in three times, the probability of missing it three times would be # x # × # ###: which being subtracted from 1, there will remain *** for the probability of throwing it once or oftener in three times; therefore the odds against throwing it in three times are 125 to 91. Again, suppose we would know the probability of throwing an ace once in four times, and no more : since the probability of throwing it the first time is #, and of missing it the other three times is 3 × 4 × 4 it follows that the probability of throwing it the first time, and missing it the other three successive umes, st X # X # x # == *:: but because it is possible to hit it every throw as well as the first, it follows, that the probability of throwing it once in four throws, and missing the other three, 4 × 125 500 1296 T 1296 tracted from 1, there will remain H'.” for the probability of throwing it once, and no more, in four times: therefore, if one undertake to throw an ace once, and no more, in four times, he has 500 to 796 the worst of the lay, or 5 to 8 very neal".

Suppose two events are such, that one of them has twice as many chances to come up as the other, what is the probability that the event, which has the greater number of chances to come up, does not happen twice before the other happens once, which is the case of flinging 7 with two dice before 4 once Since the number of chances are as 2 to 1, the
