Youxnans's First Book of Botany. Designed to cultivate the Observing 



Powers of Children. By ELIZA A. YOUMANS. i2mo. 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, Illinois, 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 ?ample of the true method 

 of teaching the elements of science in primary schools, Miss Youmans's book is deserv- 

 ing of the highest praise. In this respect 1 have seen nothing equal to it. The same 

 method, pursued in all the natural sciences, would soon give us a generation of accu- 

 rate and intelligent young obsemers of natural objects and phenomena, and change for 

 the bettar the whole tone and character of common-school instruction.

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 careful examination of its claims. We would here merely say that 

 it has recently been THOROUGHLY REVISED, in view _of recent discoveries in Physics, 

 and the general acceptance of new theories respecting 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.
