A BOOK OF CONDENSED SCIENTIFIC KNOWLEDGE FOR THE MILLION. 



BY THE AUTHOR OF "I]VQ,UIRE WITHIN." 



This is a goodly sized volume of 356 pages, comprising a sort of Encyclo- 

 pedia of Scientific Information of all kinds. It is arranged with an Alpha- 

 betical Index, in referring to which you can solve almost any problem in 

 Natural Philosophy or Learned Science that may come up. It is a book that 

 will give you the cream of the information that a long course of practical ex- 

 periments and profound study has imparted to the savants and philosophers 

 of this progressive age. It contains a collection and solution of 

 Thirteen Hundred & Thirty-Two Facts In Science & Philosophy, 

 some of which , on there first discovery , puzzled the most learned an d apt scholars. 



It is useless to go into details of this excellent work. Suffice it to say, 

 that it treats on every imaginable subject pertaining to Causes and Effects, 

 and must necessarily be invaluable to all persons who desire KNOWLEDGE, 

 and whose means and position in life have prevented them from acquiring it 

 by a regular and tedious course of Study. 



We hesitate not to say, that any one who closely reads this volume will ob- 

 tain as much real learning in a few days as years of study and patient research 

 would afford them in a regular course. In a word it makes you a learned and 

 refined person with spending but very little money, tune or trouble. 



No pains have been spared by the Author to make this a popular book, in 

 fact a book for the million, and some idea may be formed of its vast usefulness 

 when we inform the reader that THE REASON WHY has an 



Index of Contents requiring Forty Columns of Fine Type. 



No person who desires to figure in refined and intelligent circles should delay pur- 

 chasing a copy of this capital work, for it will furnish thousands of ideas and im- 

 portant topics of conversation, so that the most ignorant person by reading it will 

 be posted up on all scientific subjects. 



What Haydn's Dictionary of Dates is in regard to historical events, this wonderful 

 book is in respect to scientific facts. The plan of the book and its execution, leave 

 nothing to be desired. We cftn cordially recommend this work to all those inquirers, 

 young and old, of both sa^es, who are never satisfied until they know the 

 " reason whv-" 



The man who goes out into the world, or attempts to attend properly to his 

 domestic duties, -will find himself, however abundantly supplied with books or 

 bullion, perpetually embarrassed for the want of small facts and small change. 

 This volume supplies the 



Ready Coin of Conversation, 



In the shape of SCIENCE FOR THE MILLION, and makes even the neglected in 

 early studies feel quite at home upon every topic likely to be discussed within the 

 ordinary range of the social circle. It imparts 



Practical Information on the Subject of Practical Facts. 



It may be denominated, Science made easy, or a world of useful every-day learn- 

 ing condensed into a volume for your pocket!
