RECOMMENDATIONS 



TO 



STOCKHARDT'S CHEMISTRY 



Extract from a Letter of S. L. Dana, M. D., LL. D. 

 " This book is preeminently clear, concise, practical in all its allu- 

 sions to art, simple in its arrangements, and illustrated by experiments 

 requiring- no array of costly apparatus. It is a work worthy of its 

 author, and will bear the character we have given to it, even when 

 subjected to the severest scrutiny." 



From A. A. Hayes, M. D., Assayer to the State of Massachusetts. 

 " After reading this work in the translation by Dr. Peirce, I have 

 formed the opinion that, as an easy introduction of the student to the 

 principles of chemistry, it is unrivalled by any book in our language. 

 Rarely is it possible to find an elementary work which, without being 

 voluminous, discusses so many subjects clearly." 



From Charles T. Jackson, M. D. 

 " Stockhardt's Chemistry will prove a useful elementary book in 

 teaching the principles of chemistry. It has the advantage over most 

 of the English works on chemistry, of introducing among pupils of 

 our schools and colleges the Continental system of notation, and the 

 metrical system of weights and measures. The old Daltonian atomic 

 numbers, advocated by Prout and others, is only used in England, and 

 will soon be abandoned there. It is therefore highly desirable that 

 the Berzelian system, generally employed on the continent of Europe, 

 should be introduced here. ^ Stockhardt's book will serve this valuable 

 purpose. It also conveys much useful elementary knowledge of the 

 science of chemistry, perhaps as much as could be condensed within 

 so narrow limits." 



Extract from Professor Horsford's Introduction. 

 " The qualifications of this work as a text-book for schools are 

 such as to leave little, if any thing, to be desired. The classification 

 is exceedingly convenient. The elucidation of principles and the ex- 

 planation of chemical phenomena are admirably clear and concise. 

 The book is also well adapted to the wants of teachers who desire to 

 give occasional experimental lectures at a moderate expense, and of 

 those who design to commence the study of chemistry, either with or 

 without the aid of an instructor."
