Page 38 - Public. 7. That they will become a speedier and cheaper mode of conveyance than Carriages drawn by horses. 8 That, as they admit of greater breadth of tire than other Carriages, and as the roads are not acted on so injuriously as by the feet of horses in common draught, such Carriages will cause less wear of roads than coaches drawn by horses. 9, That rates of Toll have been imposed on Steam Carriages, which would prohibit their being used on several lines of road, were such charges permitted to...
Page 20 - So important has this observation appeared to astronomers, that at the last transit of Venus, in 1769, expeditions were fitted out, on the most efficient scale, by the British, French, Russian, and other governments, to the remotest corners of the globe, for the express purpose of performing it. The celebrated expedition of Captain Cook to Otaheite was one of them. The general result of all the observations made on this most memorable occasion gives 8" -5776 for the sun's horizontal parallax.
Page 88 - They are said to attain their full growth of 10 or 12 feet at their tenth mouth, they are cut down, the twigs and leaves removed, and the stems left to soak for some days in water, to loosen the bark and wood and facilitate the removal of the pith. This last after being cleaned and made into a cylindrical shape, is cut into convenient lengths and is now ready for the hand of the...
Page 54 - ... properties : forming a large column of a clear silvery lustre, destined to span the heavens in one entire arch. Its progress in this form became steady and regular, but slow, until it reached the meridian when it commenced to form another inverted cone, with the apex pointing due west. At about 840 it became a most superb object.
Page 20 - On examining these, it will be found that, though there is very close accordance in the results obtained by the different investigators and from the different transits, yet all investigators have expressed their doubts upon those results. In the transit of 1761, the result depended almost entirely upon an accurate knowledge of the differences of longitude of very distant stations, which are undoubtedly subject to great uncertainty. In the transit of 1769 it happened that the result depended almost...
Page 24 - ... that the mean longitude of the first satellite, minus three times that of the second, plus twice that of the third, is always equal to two right angles.
Page 34 - SOUP FOR CHILDREN. With that remarkable estimation of the greatness of small things which is one of the most valuable of his many high intellectual qualities, and with a tender appreciation of the importance of small people, Baron Liebig devotes a special article in an English scientific periodical to the description of a new article of diet which he conceives to be the most fitting substitute for the natural nutriment for those children who are by circumstances robbed of their mother's milk. It...
Page 22 - Chili, at 8".50. 3. The solar parallax can also be computed from the law of universal gravitation. The principle may be thus stated : The motion of the moon round the earth is disturbed by the unequal attraction of the sun on the two bodies. The magnitude of the disturbance will be in some proportion to the distance of the disturber, when compared with the relative distance of the two disturbed bodies ; and this ratio of distances is the inverse ratio of the parallaxes of the sun and moon. By selecting...
Page 34 - ... starch be not unfitting for the nourishment of the infant, the change of it into sugar in the stomach during digestion imposes an unnecessary labor on the organization, which will be spared it if the starch be beforehand transformed into the soluble forms of sugar and dextrine. This he effects by adding to the wheaten flour a certain quantity of malt. As wheaten flour and malt flour contain less alkali than woman's milk, he supplies this . when preparing the soup.
