and the estimated rate was four in a minute." Besides these, 

 " there were two or three which evidently formed part of the as- 

 semblage" which were, however, different in colour, magni- 

 tude, direction, " precisely like the multitude of common shooting 

 stars without trains" Still, Mr. Twining refers the former to 

 the same class as appeared in 1833, since they seemed, he 

 says, to emanate from a fixed point in Leo, which was either 

 the same as the radiant of last year, or very near it. He 

 confesses, however, that, as the scale was so greatly dimi- 

 nished, he has formed no decided opinion whether this whole 

 display is to be considered a slight recurrence of the meteoric 

 phenomenon of Nov. 13. 1833, or not. The zodiacal light 

 was visible, all the while, as high as the neck of the Lion, but 

 not so bright as on Nov. 9. The place of observation wa9 

 West Point. 



3. The third notice of the phenomenon in question is con- 

 tained in some miscellaneous remarks by Professor Olmsted 

 on the zodiacal light, (p. 417.) The principal facts stated are, 

 that the zodiacal light passed from the eastward to the west- 

 ward about Nov. 13., according to prediction, and that on the 

 morning of the 13th "there was a slight repetition of the 

 meteoric shower." The particulars differ but little from those 

 already given (Mag. Nat. Hist., viii. 140.) in the New York 

 Journal of Commerce. The radiant appeared to be u a little 

 to the northward and westward of the place it occupied last 

 year" (1833). In 1833, decl. 20°, r. a. 150° ; in 1834, decl. 

 30° 1 5', r. a. 1 44° 30'. The point did not vary for three hours, 

 from which the professor concludes that " the source of the 

 meteors was beyond the earth's rotation, and consequently 

 beyond the atmosphere." Four meteors ascended from the 

 radiant point; one towards it ; three moved horizontally from 

 west to east, south of Orion and Canis Major. The zodiacal 

 light was seen extending from the horizon, and terminating 

 near the radiant. These observations were made by Pro- 

 fessor Olmsted, Mr. tutor Loomis, and Mr. pupil Haile, of 

 Yale College. 



Professor Olmsted states, further, that though decidedly in- 

 ferior to the display of 1833, this display was more than any 

 before or since Nov. 13. 1834, and that no remarkable fall 

 was seen any whore south of Yale College, although appear- 

 ances at West Point, nearly in same latitude, and at Andover 

 (Massachusets), to the north, were remarkable. Furthermore, 

 we learn, that, in 1831, on Nov. 13., between 3 and 4 o'clock, 

 a.m., Dr. Wright, living in Ohio, noticed an unusual shower 

 of meteors in that state, g
