SWAIN'S NEW PLANETARIUM for Common Schools, $ 15.00 LARGE PLANETARIUM, for Colleges; showing 66 the Motions of all the Planets, and all other Phenomena connected with the science of Astronomy, 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. SCHOOL APPARATUS. 49 3 2 A SET OF MODELS OF THE HUMAN EYE, IN THREE PARTS. 1. The Anatomy of the Eye. 2.

IMPROVED EDUCATION TABLES. All who have purchased these Tables testify unanimously that it is wonderful to see what progress children make, by using them, in learning the Alphabet and to spell correctly. They are the most amusing and instructive Toys that can be put into the hands of Children, either at home or in the School-room. They consist of a Frame, on which are Sets of Letters arranged in Alphabetic order. These letters are fastened to the frame by a button sliding in a groove, and can be carried to any part of the frame separately, and formed into words and sentences in grooved lines made for that purpose in the upper part of the Frame. The Figure Tables are furnished with Figures and Signs, movable in the same way, and by means of which all the Rules of Common Arithmetic may be illustrated.
