cellence of attainment held out to him without diligence and persever- 

 ance. It is not the idler, the tritler, the young man who wastes his 

 time in unprofitable society, who shuns close application that will win 

 the prize — the race is to the swift, the battle to the strong. It is not for 

 a moment to be supposed that our author inculcates the undue tasking 

 either of the mental or physical powers. He ministers sound lessons 

 of a different character towards the close, and then, with a solemn ap- 

 peal, calls on his hearers to act, and concludes in a spirit the most seri- 

 ous. 



"In a little while, the fashions, the riches, the empty pleasures, and 

 the tinsel honors of this life, will have passed away. We can carry 

 with us into eternity nothing, of which the soul is not the treasury. 



We shall never all meet together again in this world, but we shall 

 meet before the Judgment. Then may each of us be able to present

 men to it, convinced that they will derive from it useful instruction, that 

 its precepts will tend to enlighten their heads and purify their hearts, 

 and satisfied that its gifted and honored author desires no other revvard, 

 than such results in such minds. 



Central Sun of the Uiiivcrsc.—Prof. Midler, of Dorpat, from a 

 comparison of catalogues of stars since the time of Bradley, concludes 

 that the Pleiades constitute the central group of the system of stars 

 which compose the Milky Way. and that Alcyone, one of that group, 

 is the central sun, about which our sun with its attendant planets, and 

 the whole mass of stars which sparkle in the vault of night perform tlieir 

 revolutions. The time of one revolution of our sun around Alcyone 

 he estimates at 18 millions of years. Prof. Schumacher entertains 

 doubts as to the correctness of these conclusions. 



Our readers will find a full and valuable paper on the anatomy of 

 the spectrum femoralum in the July and August No. of llie Proceedings
