THE NEW SOLAR TELLURIC GLOBE. This new article of Apparatus is a six-inch Terrestrial Globe, of the best manufacture, mounted on an axis inclined 23 degrees from a vertical, which axis is attached to one arm of an index, which turns in the centre upon a metallic base, on which are represented the signs of the Zodiac, the days of the month, &c. In this centre is a perpendicular wire, upon the top of which is a small gilt ball, representing the point occupied by the Sun. By moving the Index, the Earth is made to revolve about the Sun, while the Index points out the different Signs through which the Earth passes in the different months of the year, and also the time when the Equinoxes occur. The reasons for the changes of the Seasons, the length of Days and Nights, causes of Eclipses, the Latitude and Longitude of different places, and all other phenomena which are usually taught from Globes, may readily be explained by this. We place this near the head of our list, because we think it better adapted for general use than any other Globe of the same size, and it ought to be in every school in the country. Each Globe is accompanied with a little Manual, explaining its use, and giving quite a number of Problems for amusement and instruction. Price of Globe and Book, $7.00.

THE BLACK DRAWING GLOBE. This is an 18 Inch Globe, covered with a Black Preparation suitable for Marking on with Chalk, and having the Parallels and Meridians drawn upon it, and is for teaching Map-Drawing and Geography. Price of each, Packing Box for do., $18.00 3.00 This is one of the best pieces of School Apparatus extant; instead of revolving on its poles, it turns on a wire, which is inclined twentythree and a half degrees from a vertical. A circle resembling the brazen meridian surrounds this Globe. It coincides with the Plane of the Ecliptic, and turns on two points representing the Poles of the Ecliptic. On the stand around the wire on which the Globe turns, the Months and Days of the Year, as well as the Signs of the Zodiac, are marked, and attached to the Revolving Circle is an Index, pointing to the Calendar below. By making this Index point to any day in the year, the position of the earth in regard to the sun on that day, the sun's declination, the length of day and night, the season of the year, &c., are at once exhibited to the eye, and so simply that any child can understand the various phenomena. There are two sizes, the smaller one 5 inches in diameter, And the larger, 10 inches in diameter, A Book of Explanations accompanies each. $3.00. 10.00. No. 1.-JOSLIN'S SEMI FRAME GLOBES.

SWAIN'S NEW PLANETARIUM for Common Schools, LARGE PLANETARIUM, for Colleges; showing the Motions of all the Planets, and all other Phenomena connected with the science of Astronomy, $15.00 50.00 The instruments for exhibiting the planetary motions, to be found in our highest institutions, are often quite expensive, but seldom in working order. The expensiveness and complexity of these instruments hitherto have doubtless prevented their general adoption. Mr. Benjamin O. Swain, of Gloucester, Mass., it is believed, has constructed an apparatus so simple and manageable, and so happily adapted to its purpose, that it will become an inmate of all schools, and enable the teacher to communicate to the youngest and the least acute a correct idea of the heavenly motions. An inspection of other instruments would, we think, justify this assertion. |
