NATURE. 



active and busy people, who have little time to read extended 

 reviews and elaborate treatises. 



Nature is, moreover, well calculated to be of great service 

 to teachers in any way connected with Science, or who give a 

 place, however small, to Science in their course of instruction. 

 It will keep them informed of all that is most recent and 

 valuable in Science, and enable them to add constant freshness 

 and interest to their instruction. 



In order to make the paper more and more valuable to the 

 general reader, and to supply a want which it is believed is felt 

 by many, series of Papers, profusely illustrated, have been re- 

 cently commenced, consisting of interestingly and instructively 

 written articles, on particular scientific subjects — Scientific 

 Discovery, Applications, History, Biography — by some of the 

 most eminent scientific men in the kingdom. Among the 

 works which are appearing, or will appear in NATURE shortly, 

 the Publishers are already enabled to announce the following : —
