Desaguliers sometimes opposed the patents out of charity, and they consoled themselves with the conviction that he did it out of envy. A principal object which Dr. Young proposed to himself in his celebrated Lectures on Natural Philosophy, was to hinder projectors from becoming the dupes of their own presumption and ignorance, for it is amazing with what rashness they will enter upon undertakings for which they are utterly unprepared. It was remarked, when the reward of twenty thousand pounds was offered by Parliament for a method of obtaining the longitude at sea, that the greater part of those who contended for the prize did not even comprehend the problem to be solved; and hundreds wasted months, and years, in the attempt to discover Perpetual Motion, and often fancied their attempts had been crowned with success, because they were never at the pains of ascertaining what perpetual motion meant.

open grate consumes fuel with rapidity be cause the air, which is the supporter of combustion, has uninterrupted access to the fire; while with a close-stove the air can be limited to what is just sufficient to keep the fuel ignited. There is the gain, but the gain is not all. With the common grate, the air which goes to the fire is carried up the chimney, and gives place to colder currents from the crevices of windows and doors. As the close-stove draws less than the grate, in the same degree less air is taken from the room, and less abundant are the fresh streams brought into it from without. It is this absence of ventilation which constitutes a large part of the economy of stoves. The departure of the heated air is retarded, and the shades of evening find a portion which was warmed by the morning fire still lingering in the pent-up apartment. Dr. Fyfe has demonstrated in the Encyclopædia Britannica the startling fact, that in a moderately-sized room, if the air were kept at the promised temperature for the promised The mania is over for erecting water- price, the action of the fire in an entire day engines which refuse to work; but while would be incapable of changing once the there is game to be caught it will not be whole of the atmosphere.

Not only loss of money, but loss of life and limb, is sometimes the result of inattention to natural laws. Persons who ride in a carriage seldom reflect, unless they read it in a book of science, that the motion of the vehicle is communicated to themselves, and that whatever the rate at which they travel they have a forward impulse to the same amount. A horse runs away; they leap out, and expect to alight as gently as if the carriage was standing still: instead of which they are hurried to the ground with their acquired velocity, and probably break their legs, if they are not killed upon the spot. But terror often impels to rashness where knowledge counsels prudence. It is not the only occasion in which science is easier to learn than to apply. No one can be better aware than a seaman that the world is round, and yet a sailor was once flogged because his captain had forgotten it. Two men-of-war, one larger than the other, were sailing in company, when the man on the look-out from the larger descried a ship in the horizon, which was not reported by the watch of the smaller vessel. The catof-nine-tails was the penalty of his negligence. But the same occurrence happening shortly afterwards to a second person, it was remembered that the taller mast could overlook a portion of the curvature of the earth which must interpose to hide distant objects from the man on the lower, and that the sole fault of the supposed culprit was not to have been able to see through the ocean. The anecdote is related in the 'Fragments of Voyages and Travels;' and those who have not read it there should do

ing, drinking, walking, riding-man has within himself and the objects which surround him a perpetual exemplification of the greatest discoveries of some of the noblest intellects that ever adorned the earth. If the speculations of science are sublime, the materials from which it is constructed or to which it applies, are ordinarily the homely things which we see and touch and taste every instant of our lives. Nature, if we may so speak, is a humble artificer. What she does on a grand scale she reproduces on a small one. Newton's eye, glancing from earth to heaven, saw the cause of the planetary motions in the fall of an apple; and a school-boy who whirls a stone in a sling has actually produced a close imitation of the machinery which is hurrying the earth round the sun. The man of science that sips his cup of tea and ponders its phenomena must summon to his aid hydrostatics, pneumatics, chemistry, with some of the most refined and beautiful parts of optics; and though he should be what Dr. Johnson playfully styled himself, a hardened and a shameless teadrinker, whose kettle has scarcely time to cool,' he would find that he had finished his teadrinking long before he had exhausted the philosophical lessons. Or to take an instance, the most unlike we can recall-the almanac, which is in every house and hand, is a mere convenience of domestic life but how intimately is it connected with the laws of the universe? Not one in a thousand properly comprehend it for the want of a general idea of the movements in the solar system. The theory of eclipses, the changes of the moon, the distinction between mean and apparent time, are matters about which the current notions are vague or erroneous. M. Comte heard a well-educated man tell a youth, at a striking eclipse of the sun, that

his store of invaluable manuscripts were burnt. She complained that she found in her bed-room smoke without fire; and methinks, says Madame de Stael, it was the emblem of herself. She expected to excite homage, and provoked contempt. Her knowledge was doubted, her airs ridiculed, and she was not more hated than she was thoroughly despised. Madame du Châtelets are fortunately rare; but in whatever proportion knowledge, which should ornament and enliven existence, is turned to exaction and ostentation, in the same degree will it be wished that philosophical women were more feminine and less profound. These are the abuses of knowledge, which need not affect its use. There is a medium between a quiet, humble fool,' and the female pedant, who should walk in breeches and wear a beard.'

the appetite that is forced is less likely to, upon a piece of her translation, raised more return. Nor is it any use to set them to disturbance than Newton did himself when study science in books. They must be taught by word of mouth and visible examples; for natural philosophy, unintelligible to them when read, is readily taken in when told or shown. But their teachers must understand what they attempt to explain. Children are not to be imposed upon, like their elders, by mystic verbiage; and we infallibly confuse them when we are confused ourselves. Aptitude on their part must be met by intelligence and skilfulness on ours. It is indeed the great drawback to the scheme that the requisite qualifications are rarely to be met with in mothers, upon whom the early education of children devolves; and the deficiency is one which, in spite of all that has been said of the unfitness of the study for their sex, we cannot but think they would do well to supply. Miss Edgeworth justly considered the defence of the Edinburgh wit to be complete when he gave utterance to the lively and happy observation,-'I do not care about the blueness of a lady's stockings if her petticoats are only long enough.' It is the ostentation of knowledge, and not the knowledge itself, which disgusts, and is doubly offensive when female aspirants are voluble upon subjects of which they understand little-except perhaps the jargon. Pretension is repulsive where we look for reserve, and the woman purchases knowledge too dearly who exchanges for it the attributes which are the charm for her sex. Her native virtues are of more value than acquired learning. The Marchioness du Châtelet, who translated and annotated Newton's Principia, was one of these pedantic ladies who studied science that it might minister to vanity, and Madame de Stael, the bedchamber woman of the Duchess of Maine, well known by her lively Memoirs, has handed down some traits of her character, which should scare away imitators as the drunken slave scared Spartans from intoxication. She arrived on a visit at midnight, the day before she had settled to come, occupied the bed of another lady who was hastily displaced, complained of her accommodation, and tried a fresh room on the following night; and, still dissatisfied, inspected the whole of the house, to be sure of securing the best apartment it contained. Thither she ordered to be carried half the furniture of the place, chose not to appear till ten o'clock at night, when she made her company less agreeable than her absence, by her arrogance and dictation; could endure no noise, lest her ideas should be disarranged, and, some ink being spilt

We hope there are few specimens left of the sensual school who overlooked the highest part of man, and denied the utility of everything which did not minister to bodily comfort. It is inconceivable that any one of them could be consistent in the doctrine, could only see in a noble tree the materials for boards, food for cattle in the verdure of the field, and medicinal properties in the flowers of the garden; or, if such a man did really exist, he was a subject for compassion, not for argument. Tried by the mere test of pleasure, intellectual gratification is a deeper delight than corporal luxury. But natural philosophy combines both advantages in the highest degree. It has helped on the useful arts to that extent that there is hardly a philo sophical speculation which has not yielded, sooner or later, a substantial result, and added to the convenience or the indulgences of life. What can appear to concern less than the eclipses of Jupiter's satellites, or the thousands of stars, which merely look like spangles in the sky; and yet both one and the other are made the means of determining the longitude at sea, of finding the road to any given place over the wide and pathless waste of waters. The niceties of astronomical observations are not within the compass of popular science. But without travelling out of our beat, it would be easy to show that an ordinary knowledge of philosophical truths has filled the world with substantial products. The greater part of the history of scientific civilization is lost, of course, in the night of time. aggregate result of improvement is apparent.
