Corrections nud Remarks 



For Rubernpre o-eacl Kubempre. 



Column 'Appearance, &c.,' after Favis at end of the deserijHion, add 

 No detonation seems to have been heard. 



After Chelmsford add [seen also in London ; see the above General 

 List.] 



Dele 1858, Aug. 1 3, &" 39"" p.m., kc, stiiUnrj out the whole of this first 

 accordance of the List. See the Xote in the Erratum of p. 120. 



After (Berne time) add A fine fireball; long, slow flight, as if 

 impeded, but uniform in brightness up to sudden disappearance. 

 White, yellowish, or pinkish, with tail of fading sparks, and 

 some light-streak left upon its course. No detonation heard. 



In column of ' Eemarks ' add [Calculation of the meteor's real 

 path by G. von Niessl ; ' Verhandlungen des Naturforschenden 

 Vereins in Briinn,' Bd. xvii.] 



Column of ' Eemarks '/'"' Dec. 27 read Denning 27. 



Column ' Observed Radiant,' after x Ursic Majoris, add The three 

 observed paths emanate very nearly from one point. 



Column ' Places of Observation,' after Dundee, &;c., add Several 

 good accounts of the meteor collected and reduced by J. E. 

 Clark. 



Column of ' Remarks \for Dec. 2, 1877, o-ead Denning 2, 1877. 



Column ' Observed Radiant-point,' /w il° read 55°. 



Column ' Length of Path,' &c., after estimated ; add but the 

 observations indicated a rather slow motion. 



1858 Aug. 13 e"" 39™ p.m. ct scq. to end of the paragraph on p. 46, 

 dele all the Remarks on this accordance, which is a mistaken 

 and unreal one ; and append the following Note : — Oct., 1879. 

 A letter just received from Mr. Caws states that the meteor 

 which he saw near Ryde was certainly observed in the autumn 

 of one of the years 1863 or 1864, and not, as his original 

 description seemed to intimate, in the year of Donati's comet, 

 1858. The fireball which it described was doubtles^s the grand 

 one which at dusk on the moonlit evening of Nov. 11, 1864, 

 passed over the southern part of France, and which was pretty 

 widely observed there, and in Kent (see these Reports, vol. for 

 1865, pp. 78, 120). The contemporary descriptions, with the 

 addition of this new one, only allow the real path to be roughly 

 assigned (as follows) as a good average combination of the 

 plentiful but loose materials. The meteor began its flight 70 or 

 80 miles above the neighbourhood of Macon, or of a point mid- 

 way between Lyons and Clermont, and passing in mid-path over 

 the southern part of the mountains of Auvergne, ended its 

 course about 50 or 60 miles above a point mid-way between 

 Cahors and Montauban, on the rivers Lot and Tarn. The whole 

 distance of 150 or 200 miles was traversed in about 5 seconds, 

 with a speed of about 35 miles per second, from the direction, 

 roughly, of a radiant-point at about alt. 5° or 10°, in the N.E. ; 

 celestial position 85° + 35° ( ± 10°.) The parabolic speed of a 

 meteor with this radiant-point is 32-5 miles per second. A bright 

 streak visible in the twilight sky (at Rhodez, and at Pamiers in 

 Arri&ge) for several minutes, when the nucleus broke up rather 

 suddenly at last, remained along its course like an after-glow 

 of the splendidly luminous white tail, similar in brightness to 

 the head, by which the nucleus was pursued. Its appearance, 

 although extremely brilliant, eclipsing the full moonlight at 

 Rhodez and other places near its path, was unaccompanied by 

 any audible report.
