degrees north of the equator, is considered positive, and if she sails
south 25 degrees: her motion first diminishes her latitude, then
reduces it to nothing, and finally gives her 5 degrees of south lati-
tude. The sign - prefixed to the 25 degrees, is retained before the
5, to show that this is what remains of the southward motion, after
balancing the 20 degrees of north latitude.

42. A quantity is sometimes said to be subtracted from 0. By this is meant, that it belongs to the negative side of 0. But a quantity is said to be added to 0, when it belongs to the positive side. Thus, in speaking of the degrees of a thermometer, 0+6 means 6 degrees above 0; and 0-6, 6 degrees below 0.

AXIOMS.

43. An AXIOM is a self-evident proposition.

1. If the same quantity or equal quantities be added to equal quantities, their sums will be equal.

2. If the same quantity or equal quantities be subtracted from equal_quantities, the remainders will be equal.

3. If equal quantities be multiplied into the same, or equal quantities, the products will be equal.

4. If equal quantities be divided by the same or equal quantities, the quotients will be equal.

5. If the same quantity be both added to and subtracted from another, the value of the latter will not be altered.

6. If a quantity be both multiplied and divided by another, the value of the former will not be altered.

7. Quantities which are respectively equal to any other quantity, are equal to each other.

8. The whole of a quantity is greater than a part. 9. The whole of a quantity is equal to all its parts.

RULE 4.-When a mixed number and a fraction or two mixed numbers are given to find their difference; reduce the given fractions to fractions of equal value having a common denominator, by Prob. II. Then, appending these fractions to the integers to which they belong, subtract that mixed number which has the smallest integer from the other; in subtracting the fractional part of the one from the fractional part of the other, if the numerator of the subtrahend be less than that of the minuend, apply Rule 1 above, and then the Rule of Subtraction, p. 66, vol. I.; but if the numerator of the fractional part of the subtrahend be greater than that of the minuend, apply Rule 3 above; add the difference thus obtained to the fractional part of the minuend, and then take the difference between the remaining integral parts as before. This difference, prefixed to the difference of the fractional parts thus obtained, will give the difference required.

The reason of this rule is obvious from the reasons assigned for the preceding rules.

MULTIPLICATION OF FRACTIONS.

PROBLEM VIII.

To multiply fractional quantities and mixed numbers by cach

other.

RULE 1.-When the given fractions to be multiplied are proper fractions, multiply all their numerators together for the numerator of the product, and all their denominators for the denominator of the product; the result placed in a fractional form will be the product required.

The reason of this rule may be thus explained; take, for example, two proper fractions and, and let it be required to find their product. You will recollect that the fraction may be considered as of 5 (see No. 7, p. 133, vol. ii.); you will also remember that to multiply the fraction by 5, we must multiply the numerator only, and that this product will be (see No. 11, Principle 2, p. 134); now we wish to have the product of by of 5; we must therefore take of the product of this fraction by 5, that is, we must take of 15; but, by No. 8, Def. 3, p. 133, this becomes, the proper answer to the question. The process, then, is plainly this; in order to multiply one fraction by another, you first multiply the multiplicand by the numerator of the multiplier, and then divide the product by its denominator (see No. 12, Principle 3, p. 134); but this process is equivalent to that expressed in the words of the rule; for multiplying the numerator of a fraction by a whole number increases its value, and multiplying the denominator by the same diminishes its value; and the numerator and denominator of the multiplier are considered as whole numbers when taken by themselves.

Another view of the reason of this rule may be taken perhaps with more simplicity and propriety as follows: When we multiply a fraction by any number we repeat or take it as many times as that number denotes; when we multiply it by unity or one we take it one time; and when we multiply it by a proper fraction we take it a part of a time; therefore, in the latter case, we must take such a part of the multiplicand as that part denotes; but to take such a part of a fraction as another fraction denotes is to take a fraction of a fraction, which, according to No. 8, Def. 3, p. 133, is to form a com o nul fraction; and this requires the operation described in the rule; see the place to which we have just referred.

From the preceding observations we draw the following important observations, viz.: That whatever be the nature of the multiplicand, 1, if it be multiplied by a whole number greater than unity, it is increased; 2, if it be multiplied by unity itself it is neither increased nor diminished; 3, and, if it be multiplied by a proper fraction it is diminished, that is, the product is always less than the multiplicand.

When the product of several fractions is required, the preceding rule is applicable to any two of them; it is then applicable to the product of these two, and another of them; then to the product of these three and another of them; and so on, whatever be their number; so that the rule for reducing compound fractions to simple ones, and for multiplying any number of fractions together is the same. This rule is, therefore, capable of the same abridg. ment, by the method of cancelling factors, explained at No. 15, p. 328, col. 2, where the rule for this process is given.

N.B. The answer obtained by the rule above must be reduced to its lowest terms.

sont d'un âge plus avancé, et trouble la paix des familles.—Bacon.

Assuming the values as given in the question, we have a = 28, 630, 34, and d=50. By substituting these numbers in equation (6.), we find z=256e. By substituting the same numbers, with the value of e just obtained, we find y 134 9381 f; and by substituting the values of e and ƒ thus found, in equation (10.) we find ≈ 42.361 feet, which is the length of the ladder required. From this value of x, the three distances A 0, B o, and co are found, by substitution in equations (1.), (2.), and (3.), to be respectively, 31.789 feet, 29.908 feet, and 25-268 feet. This question was solved by J. SowDEN; DOUGLAS; A. SKERRITT (Holbrook); CAROLUS (Padiham); and many others.

SOLUTION OF QUERY 2, P. 240, col. 2.

Let x and y be the two numbers. Then, by the question xy= +y; Whence, we have, xy—x—y, by transposition; or, (y-1) y; whence, x = y

y-1

Now, by assuming the value of y, we can from this expression, find the value of x which will answer the conditions of the question. This formula may be put into the words of the following rule ; From any number greater than unity, subtract unity, and divide the number by the remainder, the quotient and the number assumed will be the two numbers required.

EXAMPLE.-Take any number 7 for the value of y, one of the numbers; then 7-1-6, and 7÷6=14; whence 7 and 1 are the numbers required. Proof: 7+18); and 7×14=8.

Il faut de plus grandes vertus pour soutenir la bonne fortune que la mauvaise.-La Rochefoucauld.

Ceux qui se plaignent de la fortune n'ont souvent à se plaind: e que d'eux-mêmes.- Voltaire.

Le gloire des grands hommes se doit toujours mesurer aux moyens dont ils se sont servis pour l'acquérir.-La Rochefoucauld.

GOUT.

Il y a dans l'art un point de perfection, comme de bonté ou de maturité dans la nature: celui qui le sent et qui l'aime a le goût pafait; celui qui ne le sent pas et qui aime en deça ou au delà a le goût défectueux. Il y a donc un bon et un mauvais goût, et l'on dispute des goûts avec fondement.-La Bruyère.

GRANDEUR.

La fausse grandeur est farouche et inaccessible: comme elle sent son faible, elle se cache, ou du moins ne se montre pas de front, et ne se fait voir qu'autant qu'il faut pour imposer et ne paraftre point ce qu'elle est, je veux dire une vraie petitesse. La véritable grandeur est libre, douce, familière, populaire. Elle se laisse toucher et manier; elle ne perd rien à être vue de près; plus on la connaît, plus on l'admire. Elle se courbe par bonté vers ses inférieurs, et revient sans effort dans son naturel.-La Bruyère.

Les grandeurs sont comme les parfums; ceux que les portent ne les sentent quasi pas.-Christine.

GRAVITE.

Une gravité trop étudiée devient comique; ce sont ecmme des extrémités qui se touchent, et dont le milieu est dignité: cela ne s'appelle pas être grave, mais en jouer le personnage; celui qui songe à le devenir ne le sera jamais.

Elle établit en nous, peu à peu, à la dérobée, le pied de son autorité: mais, par ce doux et humble commencement, l'ayant rassis et planté avec l'aide du temps, elle nous découvre tantôt un furieux et tyrannique visage, contre lequel nous n'avons plus la liber é de hausser seulement les yeux.Montaigne.

C'est passe temps aux mères de voir un enfant tordre le cou à un poulet, et s'ébattre à blesser un chien et un chat. Ce sont pourtant les vraies semences et racines de la cruauté, de la tyrannie: elles se germent là, et s'élèvent après gaillardement, et profitent à force entre les mains de la coutume.-Iden.

E.--N. M. L. (Barnard Castle): His last exercise is better than the former.-Y. A. S.: Her verses might be improved.-T. J. W. had better make up his mind from our columns. GEORGIUS: We are instructed to say that the whole 16 vols. of Mr. Cassell's Library will be in print within a fortnigt.,-that is, reprinted.-T. GUY (Broomside): Go, in the passage "Go to the ant, thou sluggard," &c is not an interjection, but the 2nd person singular of the imperative mood of the verb to go. In the passages quoted from James, the words go to are the translation of the Greek age, which, like the Latin age, signifies, literally, to do, or to be doing, or to hold, weigh, or consider; they might, therefore, be translated, CONSIDER, OF WEIGH WELL, what I am going to say, it is, therefore, used adverbially, like the words behold, see, look, come now, well, &c. The same words, go to, in the passages quoted from Genesis, are the translation of the Hebrew haba, which signifies, literally, to give place, or set, that is, to put yourselves in the attitude of attention; as much as to say hearken, listen, &c., and is used adverbially just like the preceding words. As to the translation of Exod. xxxii. 35, it is so literal as to be obscure; it should be "they were the originators of the calf which Aaron made." The fact is, they compelled him to make it, and he submitted to them through fear.

LITERARY NOTICES.

GIN AND WATER; a pair of pictorial designs by Kenny Meadows, portray-
ing the effects arising from the indulgence of those potent liquide. In the
first, GIN, we have the interior of the drunkard's home, with a glimpse of
the horrors which belong peculiarly to such homes; in the second, WATER,
we see how comfort, cleanliness, and peace attend the steps of the temperate
man. The contrast is well sustained, and the pictures-which measure
24 inches by 16 inches-cannot but be popular. We have had too many songs
and pictures in praise of the drinking customs of our country, and we
are glad to perceive that our poets and artists are beginning to discover
that they may get inspiration even out of water-
"Wine, wine, thy power and praise

Have ever been echoed in minstrel lays;
But water, I deem, hath a mightier claim
To fill up a niche in the Temple of Fame ?"

These pictures, which should be framed and hung over every cottage chimney-piece, and on the walls of every factory, and workshop, and ragged school throughout all the land, can be obtained of every bookseller for one shilling. They are exquisitely engraved on wood, by Messrs. Henry Linton and William Measom.

H. F. MCPHERSON (Grimsby): The error is now corrected. See also No. 46, p. 300, col. 1, line 60.-H. FISHER: In order to write "eleven 'thousand, eleven hundred and eleven," remember that eleven hundred is one thousand one hundred; so that the proper expression is twelve thousand, one hundred, and eleven.

R. L. A.: Phonography signifies writing according to sound; stenography means writing in a small compass. The origin and structure of the Low Islands extending from the Society Islands towards Cape Horn is the following: Coralline plants, growing at the bottom of the ocean, harbour a class of lithophytic (stone producing) insects, which, during their life, form round them a substance which after their death becomes hard as a stone. The rock-work of one generation affords a foundation to that of the succeeding, and layers are thus placed over each other till they reach the surface of the water and form islands. As soon as the rock is exposed to the air the insects quit the surface, leaving it perforated by numerous hollows; but they work for some time laterally (sideways), forming immediately under the water concealed table-reefs, which have given occasion to numerous and fatal shipwrecks. Meantime, from amid the interstices of the surface plants spring THE ILLUSTRATED EXHIBITOR AND MAGAZINE OF ART-The First Twy up, which, on their decay, are converted into soil, and thus by degrees the Parts of a new and improved Series of this work, under the title of the new island is covered with luxurious vegetation.-J.
