Youmans's First Book of Botany. Designed to cultivate the 

 Observing Powers of Children. By Eliza A. Youmans. 12mo. 

 183 pages. $1.00. 



This little book has proved a wonderful success, and is emphatically a step in the right direction. 

 Although it has been issued but a short time, it has been adopted for use in the cities of Chicago, St. 

 Louis, New York, Columbus, Nashville, Milwaukee, etc., etc., and in the States of Maryland, Illi- 

 nois, and Arkansas. It is to be speedily followed by the Second Book of Botany and six large and 

 beautifully-colored Botanical Charts, after the plan of Henslow. 



Hon. Superintendent Bateman, of Illinois, says : " As a sample of the true method of teaching 

 the elements of science in primary schools, Miss Youmans's book is deserving of the highest 

 praise. In this respect I have seen nothing equal to it. The same method, pursued in ail the 

 natural sciences, would soon give us a generation of accurate and intelligent young observers of 

 natural objects and phenomena, and change for the better the whole tone and character of com- 

 mon-school instruction. Newton Bateman, Sup't Public Instruction.' 1 '' 



Lockyer's Astronomy, accompanied with numerous Illustrations, 

 a Colored Representation of the Solar, Stellar, and Nebular 

 Spectra, and Celestial Charts of the Northern and the Southern 

 Hemispheres. American Edition, revised and specially adapted 

 to the Schools of the United States. 12mo. 312 pages. 



Teachers are delighted with this American Edition of Lockyer's Astronomy. The following 

 unsolicited testimonial from Rev. Dr. J. A. Shepherd, Principal of St. Clement's Hall, Ellicott 

 City, Md., will show the estimation is which it is held : 



" I have been a teacher of Astronomy as a specialty for more than twenty-five years, and beg to 

 say that, in my opinion, your Edition of Lockyer's Astronomy is, without doubt, 'the best text-book 

 on the subject that has ever appeared in this country. The peculiar arrangement is one which none 

 but a master-mind would have ventured to make. The illustrations are, in their way, perfect 

 little gems. I have tested the work in the class-room, and cannot but feel that this is one of the very 

 best Text-Books ever issued from the American press." 



Quackenbos's Natural Philosophy. Revised Edition. Em- 

 bracing the most recent Discoveries in the various Branches of 

 Physics, and exhibiting the Application of Scientific Principles in 

 Every-day Life. Adapted to use with or without Apparatus, and 

 accompanied with Practical Exercises and numerous Illustrations. 

 12mo. 450 pages. 



Quackenbos's Philosophy has long been a favorite Text-Book. To those who have used it, no 

 words of commendation are necessary; to those who have not, we would earnestly suggest a care- 

 ful examination of its claims. We would here merely say that it has recently been thorot/ghly 

 revised, in view of recent discoveries in Physics, and the general acceptance of new theories re- 

 specting Heat, Light, and Electricity, the Correlation and Conservation of Forces, etc. The present 

 Edition is in all respects an accurate exponent of the present state of science.
