APPARATUS 



FOR 



SCHOOLS, LYCEUMS AND ACADEMIES. 



The economy, no less than the general utility, of visible illus- 

 trations, is no\v universally acknowledged. It has had the 

 unanimous assent, so for as known, in not less than fifty con- 

 ventions of teachers, *t which were present more than ten 

 thousand persons. Apparatus is more economical than books, 

 because one instrument is sufficient for a school, instead of an 

 individual because it is more durable because impressions 

 received through the eye, especially by young minds, are more 

 clear, more rapid, more permanent, more agreeable, and, of 

 course, more efficient, man those through the ear. 



The change already effected in Schools, by the geometrical 

 diagrams and solids, is unparalleled. By them the simple 

 elements of Geometry, from an abstruse study in a collegiate 

 course, have liecome the most agreeable, as well as the most 

 useful branch in Infant Schools, and to a great extent in Com- 

 mon Schools. 



A manual, and three sheets of diagrams, one of which 

 contains the manuscript letters, can be used without the solids, 

 either in Schools or families. The price of the four articles 

 is $0,50 ; that of the whole of the geometricals is $4. A set 

 of common-school apparatus, embracing the geometricals, one 

 or two instruments for Arithmetic, several for Geography, and 

 a few for Astronomy, is $10. For Lyceums and Academies, 

 philosophical are $15; orrery, $6; tide dial, $4; seasons, $2; 

 whole 'of the asWtoomicals. $15: a convenient chemical 

 set, $2r,. 



As some counterfeit apparatus has been made, of a defec- , 

 tive elmrarter, and offered for sale under Mr. Holbrook's name,c 

 and a few individuals imposed upon, purchasers will do well 

 to lie minions of whom- they procure it. None but that made 

 under Mr. Holbrook's direction can be used with books which 

 are prepared and preparing to illustrate and apply it. 



CARTER, HENDEE AND BABCOCK have the appa- 

 ratus above-named for sale, with a large assortment of Books 

 designed for INFANT and PRIMARY SCHOOLS, for LYCEUMS, 

 ACADEMIES and elementary and practical instruction generally.
