Elements of Chemistry, i2mo. 272 pp. 



Utilizes the facts of every-day experience to show what chem- 

 Istry is and how things are studied chemically. The language 

 is untechnical, and the subject is fully il! 1 by simple ex- 



periments, in which the pupil is led by q to make his 



Dwn inferences. The author has written under the belief that 

 ''a rational course in chemistry, whether for younger or oldei 

 pupils, is something more than a lot of statements of facts of 

 more or less importance; a lot of experiments of more or less 

 beauty; or a lot of rules devised for the purpose of enabling 

 the pupil to tell what things are made of. If the course does 

 not to some extent help the pupil to think as well as to see it 

 docs not deserve to be called rational." 



Chase Palmkr. Professor in //:■■ tal School, Salem, Mass.: 



— It is the best introduction to chemistry that I know, and I intend to 

 put it into the hands of my pupils next Fall. 



A. D. Gray, Instructor in Id {Mass.) .' '. — Xeat, 



attractive, clear, and accurate, it leaves little to be d it sought 



for by one who would find the best book for an elementary course in 

 our High Schools and Academies. 



GENERAL BIOLOGY. By WILLIAM T. SEDGWICK, Pi 



in tlu' Mass. Institute of Techn r ND B. Wil« 



son, Professor in Bryn Mawr College. Parti. > pp, 



This work is intended for Co nd university students as 



an introduction to the theoretical and practical study of bi- 

 ology. It is not zoology, botany, or physiology, AUtl is intended 

 not as a substitute, but as a foundation, for these m >re s 

 studies. In accordance with the present obvious tendem 

 the best elementary biological teaching, it 

 some of the leading principles of the science on th< ntia] 



basis of a thorough examination of a limited number 1 

 forms, including both plants and animals. Part 1" rst, now 

 published, is a general introduction to the subject illusti 

 by the studv of a few types. Par; Second will contain a de- 

 tailed survey of various plants and animals. 



W. G. Fari ow, P- 

 — An introduction is always difficult to write, and I know no work in 

 which the general relations of plants and animals and the cell struc- 

 ture have been so well stated in a condensed form.
