Tin: Leeds Astronomical Society. —The 

 "Journal and Transactions " of this usi ful 3 



daring the year 1899 has been sent to us. Some of 

 the papers are very full "1' interest and instruction. 

 ■•The Planet Mercury as a View Point," by the 

 President, Mr. C. T. Whitmell ; "Jeremiah Hor- 

 rocks and the Transit of Venus," illustrated by 

 a photographic plate, by .Mr. A. Dodgson ; and 

 "Astronomical Theories relating to Stoneheng 

 with two photographic views, by .Mr. Washington 

 Teasdale, may be specially mentioned. 



Meteors of striking appearance have recently 

 been seen. On July 17th. at 8.47 p.m., in brighl 

 twilight, too bright to exactly describe it- patl 

 fireball, thought by Mr. Denning to be a Scorpiid, 

 having a double head, was observed at many places 

 in the North of England. The trail it left was 

 visible for three-quarters of an hour. Another 

 brilliant meteor was observed from Slough, 

 Croydon, &c, at 11.33 on July 18th. and from its 

 extraordinary motion was described by Prof' -- 

 A. S. Herschel as "about the queerest lie ever 

 saw." 



Comets. — Giacobini's comet at the begirn 

 September will be situated in the southern portion 

 of Hercules to the north of a Ophiuchi, but too 

 faint to be seen with common telescopes. A comet 

 was almost simultaneously- discovered on the 

 morning of July 24 by M. Borelly. of Mar- 

 aud Mr. W. R. Brooks, of the Smith Observatory, 

 Geneva, N.Y.. At that time it was said to be a 

 beautiful telescopic object, having a stellar nucleus, 

 about 8th magnitude, and a small broad tail. It 

 was discovered closely east of the 5th magnitude 

 star, 38 Arietis, but had travelled rapidly north 

 through Perseus to Camelopardus by August L5th, 

 near the star y. and is said to be decreasing in 

 brightness. According to the elements calculated 

 by Herr MoTler, of Kiel, the comet was nearest the 

 earth about the end of July, and perihelion was 

 passed on August 3rd. It is known as 1900, h. In 

 the middle of August the nucleus was readily 

 visible with a telescope of less than 2 inches aper- 

 ture. With lo ; } inches aperture .Mr. Brooks finds 

 it to be duplex, but not clearly separated. 



Jupiter in 1900.— There is a white spot on 

 the northern side of the north tropical belt, bedding 

 deeplj into, if not actually breaking through the 

 dark belt. The Rev. T. E. R. Phillips first -aw the 

 objeel in 1899, on January 26th, when it had a 

 longitudeof 85*3°, System II. It had, on July 28th, 

 L900, a longitude of 325 - 9°, so that in eighteen 

 months ii ha- losl aboul L20 "( longitude, rela- 

 tively to the zero meridian of System II. This 

 would give a rotation period of 9h. 55m. 50'6s.
