- Jewish Shophar
The Jewish Shophar, a simple ram's horn, a woodcut of which, drawn from an interesting example preserved at the great Synagogue, Aldgate, London, figures at the end of this Introduction, is the oldest wind instrument in present use in the world. It is first named in the Bible as sounding when the Lord descended upon Mount Sinai, and there seems to be little doubt that it has been continuously used in the Mosaic Service from the time it was established until now. It is sounded in the synagogues at the New Year and on the Fast of the Day of Atonement. The Talmud gives ten reasons for sounding the Shophar at the New Year, which may be summed up as reminding those who hear it of the Creation, Penitence, and the Law, of the Prophets, who were as watchmen blowing trumpets, of the Temple and the Binding of Isaac, of Humility, the gathering together of Israel, the Resurrection, and the day of Judgment, when the trumpet shall sound for all. The embouchure of the Shophar is very difficult, and but three proper tones are usually obtained from it, although in some instances-xiii- higher notes can be got. The short rhythmic flourishes are common, with unimportant differences, to both the German and Portuguese Jews, and consequently date from before their separation. - The Moon’s surface mountainous

Great telescope at the Yerkes Observatory of the University of Chicago, Williams Bay, Wisconsin, U.S.A. It was erected in 1896–7, and is the largest refracting telescope in the world. Diameter of object-glass, 40 inches; length of telescope, about 60 feet. The object-glass was made by the firm of Alvan Clark and Sons, of Cambridge, Massachusetts; the other portions of the instrument by the Warner and Swasey Co., of Cleveland, Ohio. - The superstitious notions of the antients with regard to Eclipses
The superstitious notions of the antients with regard to Eclipses - Showing how the Tail of a Comet is directed away from the Sun
hese mysterious visitors to our skies come up into view out of the immensities beyond, move towards the sun at a rapidly increasing speed, and, having gone around it, dash away again into the depths of space. As a comet approaches the sun, its body appears to grow smaller and smaller, while, at the same time, it gradually throws out behind it an appendage like a tail. As the comet moves round the central orb this tail is always directed away from the sun; and when it departs again into space the tail goes in advance. As the comet's distance from the sun increases, the tail gradually shrinks away and the head once more grows in size (see Fig. 18). In consequence of these changes, and of the fact that we lose sight of comets comparatively quickly, one[Pg 249] is much inclined to wonder what further changes may take place after the bodies have passed beyond our ken. - Cornemuse, Calabrian Bagpipe, Musette
The Calabrian Bagpipe or Zampogna is a rudely carved instrument of the eighteenth century. It has four drones attached to one stock, hanging downwards from the end of the bag: two of them are furnished with finger-holes. The reeds are double like those of the oboe and bassoon. The bag is large; it is inflated by the mouth and pressed by the left arm against the chest of the performer. The Zampogna is chiefly used as an accompaniment to a small reed melody pipe called by the same name, and played by another performer. The quality of the tone produced is not unpleasing. It has five holes only, and consequently the seventh of the scale is absent, but this can be easily got by octaving the open note of the pipe and covering part of the lower opening of the chanter with the little finger. The Musette, Zampogna, and Cornemuse here shown are from specimens belonging to Messrs. J. & R. Glen, Edinburgh. - Map of the Moon

Why the weather is coldest when the Earth is nearest the Sun. - The cause of the tides discovered by Kepler
The cause of the Tides was discovered by Kepler, who, in his Introduction to the Physics of the Heavens, thus explains it: “The Orb of the attracting power, which is in the Moon, is extended as far as the Earth; and draws the waters under the torrid Zone, acting upon places where it is vertical, insensibly on confined seas and bays, but sensibly on the ocean whose beds are large, and the waters have the liberty of reciprocation; that is, of rising and falling.” - Orbit and Phases of an Inferior Planet

The extreme length of the Lamont Harp is 38 inches, and the extreme width 18½ inches. The sound chest, as with other ancient harps, is hollowed out of one piece of wood, but the back has been in this instrument renewed, although probably a long time ago. The sound chest is 30 inches long, 4 inches in breadth at the top, and 17 at the bottom. The comb projects 15½ inches. The broken parts of the bow are held together by iron clamps. - The comet of 1066, as represented in the Bayeux Tapestry
We have mentioned Halley's Comet of 1682, and how it revisits the neighbourhood of the earth at intervals of seventy-six years. The comet of 1066 has for many years been supposed to be Halley's Comet on one of its visits. The identity of these two, however, was only quite recently placed beyond all doubt by the investigations of Messrs Cowell and Crommelin. This comet appeared also in 1456, when John Huniades was defending Belgrade against the Turks led by Mahomet II., the conqueror of Constantinople, and is said to have paralysed both armies with fear. - Great Telescope of Hevelius
This instrument, 150 feet in length, with a skeleton tube, was constructed by the celebrated seventeenth century astronomer, Hevelius of Danzig. From an illustration in the Machina Celestis. The attempts to construct large telescopes of the Galilean type met in course of time with a great difficulty. The magnified image of the object observed was not quite pure; its edges, indeed, were fringed with rainbow-like colours. This defect was found to be aggravated with increase in the size of object-glasses. A method was, however, discovered of diminishing this colouration, or chromatic aberration as it is called from the Greek word χρῶμα (chroma), which means colour, viz. by making telescopes of great length and only a few inches in width. But the remedy was, in a way, worse than the disease; for telescopes thus became of such huge proportions as to be too unwieldy for use. Attempts were made to evade this unwieldiness by constructing them with skeleton tubes. - The primary Planets never eclipse one another
The primary Planets never eclipse one another - The Planetary motions very irregular as seen from the Earth
The apparent magnitudes of the Planets continually change as seen from the Earth, which demonstrates that they approach nearer to it, and recede farther from it by turns. From these Phenomena, and their apparent motions among the Stars, they seem to describe looped curves which never return into themselves, Venus’s path excepted. And if we were to trace out all their apparent paths, and put the figures of them together in one diagram, they would appear so anomalous and confused, that no man in his senses could believe them to be representations of their real paths; but would immediately conclude, that such apparent irregularities must be owing to some Optic illusions. - The Solar System
By Astronomy we discover that the Earth is at so great a distance from the Sun, that if seen from thence it would appear no bigger than a point; although it’s circumference is known to be 25,020 miles. Yet that distance is so small, compared with the distance of the Fixed Stars, that if the Orbit in which the Earth moves round the Sun were solid, and seen from the nearest Star, it would likewise appear no bigger than a point, although it is at least 162 millions of miles in diameter. - Burgmote Horns
Beautiful horns of hammered and embossed bronze belonging to the Corporations of Canterbury and Dover. The right-hand one is from Dover, where it was formerly used for the calling together of the Corporation at the order of the mayor. The minutes of the town proceedings were constantly headed "At a common Horn blowing" (comyne Horne Blowying). This practice continued until the year 1670, and is not yet entirely done away with, as it is still blown on the occasion of certain Municipal ceremonies. The motto on this horn is:— JOHANNES DE · ALLEMAINE · ME · FECIT · preceded by the talismanic letters A·G·L·A, which stand for the Hebrew אַתָּה גִּבּוֹר לְעוֹלָם אֲדֹנָי and mean, "Thou art mighty for ever, O Lord!" The horn, which is 31¾ inches long, with a circumference at the larger end of 15½ inches, is of brass, and is deeply chased with a spiral scrollwork of foliage chiefly on a hatched ground. The inscription is on a band that starts four inches from the mouth and continues spirally. The maker's name is now nearly effaced, but the inscription shows that he was a German, and the date is assigned to the thirteenth century. - A Tubeless, or 'Aerial' Telescope
From an illustration in the Opera Varia of Christian Huyghens. Attempts were made to evade this unwieldiness by constructing them with skeleton tubes. or , indeed, even without tubes at all; the object-glass in the tubeless or "aerial" telescope being fixed at the top of a high post, and the eye-piece, that small lens or combination of lenses, which the eye looks directly into, being kept in line with it by means of a string and manœuvred about near the ground. The idea of a telescope without a tube may appear a contradiction in terms; but it is not really so, for the tube adds nothing to the magnifying power of the instrument, and is, in fact, no more than a mere device for keeping the object-glass and eye-piece in a straight line, and for preventing the observer from being hindered by stray lights in his neighbourhood. It goes without saying, of course, that the image of a celestial object will be more clear and defined when examined in the darkness of a tube. - The Geometrical Construction of Solar and Lunar Eclipses

The Sun, the most important of the celestial bodies so far as we are concerned, occupies the central position; not, however, in the whole universe, but only in that limited portion which is known as the Solar System. Around it, in the following order outwards, circle the planets Mercury, Venus, the Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. At an immense distance beyond the solar system, and scattered irregularly through the depth of space, lie the stars. The two first-mentioned members of the solar system, Mercury and Venus, are known as the Inferior Planets; and in their courses about the sun, they always keep well inside the path along which our earth moves. The remaining members (exclusive of the earth) are called Superior Planets, and their paths lie all outside that of the earth. - 10-Passenger Limousine

3 inch R.F. Gun - Queen Mary's Harp
This venerable instrument, the least impaired Gaelic Harp existing, is known as Queen Mary's Harp. It is small, being only 31 inches high and 18 inches from back to front. It was played resting upon the left knee and against the left shoulder of the performer, whose left hand touched the upper strings. The comb is from 2½ to 3¼ inches high. It is inserted obliquely in the sound chest, and projects about 14 inches. - The 'Ring with Wings.' - Assyrian Form
The 'Ring with Wings.' - Assyrian Form It should, however, be here mentioned that Mr. E.W. Maunder has pointed out the probability that we have a very ancient symbolic representation of the corona [of an eclipse] in the "winged circle," "winged disc," or "ring with wings," as it is variously called, which appears so often upon Assyrian and Egyptian monuments, as the symbol of the Deity. - United States Carriage model of 1896

Another favourite instrument is the 'kimmori.' This also derives its sounding powers from gourds, of which three are usually slung from the tube forming the body. It is said by the natives to have been invented by one of the singers of the 'Brahma Loka,' or heaven of the Brahmins. The 'kimmori' is made of a pipe of bamboo or blackwood, with frets or screws, which should be fashioned of the scales of the pangolin, or scaly ant-eater, though more often they are made of bone or metal. It has only two strings, one touching the frets, the other carried above them. The tail-piece is always carved like the breast of a kite, and the instrument is frequently found sculptured on ancient temples and shrines, especially in Mysore, in the south of Hindustan. - Chicago Coal or Gravel Truck
