GENERAL INDEX 



TO THE 



AMERICAN JOURNAL OF SCIENCE AND ARTS. 



FIRST SERIES OF FIFTY VOLUMES COMPLETE. 



NOW BEADY FOR DISTRIBUTION .* 



$3 



With a steel Portrait of the Senior Editor, and an Historical Preface. 



[ 1 vol. 8vo, pp. xx and 344. ] 



This long expected volume is at last ready for delivery, and 

 will be distributed to those who have subscribed for it, with the 

 May Number of the American Journal of Science. Only a lim- 

 ited edition (500 copies) of this elaborate Index has been printed. 

 It is indispensable to all who have entire or even partial copies 

 of the First Series of the Journal, and hardly less important to 

 those who investigate any department of American, or even of 

 foreign science, whether they possess the entire work or not. No 

 pains or labor have been spared to make it full and complete, 

 and above all, accurate. It has occupied the almost undivided 

 attention of a scientific gentleman for six months merely to read 

 and correct the proof-sheets, and we do not include the great labor 

 of constructing it. Its arrangement is lucid and of easy refer- 

 ence, and a full list of figures, plates and other illustrations in 



the whole Series is given at the end. 



The Historical Preface conveys much interesting information 



concerning the origin and progress of the work. 



It may be procured of all the regular Agents of the Journal. 



All subscribers who have given notice of their desire to have 

 the General Index, and who do not receive it soon, will oblige us 

 by sending in their names a second time. 



New Haven, May 1, 1847.
