10. Le Verrier’s Planet. —The new planet, ihe existence M. Le 
Verrier demonstrated mathematically from the inequality in the motions 
of Uranus, was actually discovered by M. Galle of Berlin, Sept. 23d, 
1846. This grand discovery is announced in a letter from Dr. Briin- 
now of the Royal Observatory at Berlin, dated Sept. 25th. He says, 
* the planet resembles a star of the Sth magnitude, but with a diameter 
of two or three seconds. Its motion is now retrograde, at the rate of 
four seconds of time daily. Below are two of its places :—

1.: Improvement in the construction of the Rails and Wheels of 
: Railroads _—Mr. C. H. Greenhow of London has published a pamphlet 
3 in which he condemns flanged wheels, and recommends circular rails 
and concave tire as much better adapted to the ever varying circum- 
Stances of a long line—such as curves, loose chairs, sprung rails, &c.
