346 ANNUAL OF SCIENTIFIC DISCOVERY. 



NEW PLANETS IN 1868. 



Among the planets of 1867, No. 93 has received from Prof. 

 Watson, its discoverer, the name of Minerva, and No. 94 the 

 name of Aurora. No. 95, discovered by Dr. Luther, at Bilk, Nov. 

 23, 1867, has been called by him Arethusa. 



Planet 96 was discovered by M. Coggia at Marseilles, Feb. 17th, 

 1868; as large as a star of 11th magnitude; meantime at Mar- 

 seilles 15h. 29m. 30s. ; right ascension 9h. 33m. 59.16s. ; polar dis- 

 tance 76° 8' 50. 1''. 



Planet 97, Clotho, was discovered by M. Tempel, at Marseilles, 

 Feb. 17, 1868. 



Planet 98 was discovered by Prof. Peters, at Clinton, N. Y., 

 April 18th ; of 12th magnitude. 



Planet 99 was discovered by M. Borelli, at Marseilles, May 2Sth ; 

 13th magnitude ; right ascension, 13h. 24m. 7.92s. ; polar distance 

 99°5M9.11". 



Planet 100, called Hecate, was discovered by Prof. Watson, at 

 Ann Arbor, Michigan, July 11th. Seen by Prof. Peters, at Clin- 

 ton, N. Y., July loth, and by M. Coggia, at Marseilles, July 17 ; 

 12th magnitude ; at llh. 47m. 4.1s., mean Pains time, on the 18th, 

 as observed by Wolf, the right ascension was 21h. 7m. 4.71s. ; 

 declination 106° 22' 45.3". 



Planet 101, Helena, was discovered by Prof. Watson, at Ann 

 Arbor, Aug. 15th, at 12h. 7m. 38s. ; right ascension 23h. 53m. 

 89.61s. ; declination —0° 48' 39.2" ; 10th magnitude. 



Planet 102, was discovered by Prof. Peters, at Clinton, N. Y., 

 Aug. 23; in constellation Pisces, and at 3 a. m. on the 24th, had 

 18° 38' of right ascension and 12° 54' declination, moving slowly 

 to the east; 11th magnitude ; he proposes to call it Miriam. 



Planet 103 was discovered by Prof.' Watson, at Ann Arbor, 

 Sept. 7th ; of the 10th magnitude. Planet 104 was discovered Sept. 

 13th ; of the 12th magnitude ; planet 105, Sept. 16th, of the same 

 brightness; and planet 106, Oct. 10th, of the 10th magnitude; the 

 last three by Prof. Watson, at Ann Arbor. 



METEORIC SHOWER OF 1868. 



The shower of Aug. 10, not well observed in this country, was 

 quite brilliant in Europe. From a paper read by Mr. G. Forbes to 

 the British Association, in 1868, it appears that the hourly average 

 on the evening of the 10th was 20, which, when compared with 

 the average of 25 last year, shows that the shower has not yet 

 ceased decreasino; since the maximum in 1863. As nearlv as can 

 be determined the radiant point is R. A. 2h. 16m. N. P. 1). 31°. 

 The point discovered last year is R. A. 2h. 43m. N. P. D. 29°. 30". 

 On the night common to the 11th and 12th of August, the meteors 

 were far more erratic. 



The color of the meteors was almost uniformly white, but on 

 the evening of the 10th, at 6 minutes past 11, an erratic one pass-
