1880. 



For Market Harborough 7-ead Coventry. 



(In the column 'Nearest known Radiant-point, Sec.'), for D., 8 



(1877) read Denning (Dec-Jan., 1876-77). 

 (In the column 'Length of Path, &:c.'), for about 7 sec. ; velocity 



18J read 3 or 4 sees. ; velocity about 35 (parabolic velocity 83). 

 (In the column ' Observer, &c.'), erase the small n-oodeiit. 

 (In the column ' Position, &c.'), for passed through an hour angle, 



&c., read disappeared just below rj Ursie Majoris. 

 To vol. for 1872 subjoin t/w foot-note : * In the note at p. 103 of that 



volume for 160 + 51 7-ead 150 + 61 ; and for 155 +47 read 



160 + 49 ; (Heis M^, 1864 and 1867 ; = 162 + 59, 1877.) 

 For 155 + 47 read 160 + 49. 

 For Beckingham read Rockingham. 



For vol. for 1878 read yo\. for 1877. 



For near e read near e, or (more exactly) near 5. 



Dele all tJie text from and also . . . as far as Perse'ids of August 

 10. In the foot-note, for meteor-tracks of this shower .... 

 on August 10 and 11, rcflfi meteor-tracks of the shower . ... on 

 August 10 and 11, 1871. And for the fellow-comet, 1870 

 I .... to end of the note, read a near companion radiant- 

 centre. 



For The cases .... are perhaps exceptions read The case of the 

 accordance noticed above (p. 326) between the comet 1825 II. ?s 

 (— 0'115, Oct. 7, 134° + 77°) and a briefly enduring meteor- 

 shower, noted by Mr. Denning on the niglits of October 3 and 

 4, 1877, at 130° + 79°, may perhaps be an exception. 



N. 50, tf 1870 I S ; for 43-5 + 53 read\ 

 25-5 + 45. J 



[IVbte — This last and the two preceding corrections relate to an 

 error, rectified by the last, of the radiant-point assigned in the 

 cometary radiant-list of the Report of the year 1875, to the 

 comet 1870 I. By the corrected place this comet is entirely 

 separated from all appearance of connection with the ordinary 

 August Perseid-shower ; and the conjecture raised in the above 

 noted passages of the possible origin of a double radiant-centre 

 in the August Perseid-shower of 1878 from the concurrent 

 presence of two nearly coincident comet-orbits in connection 

 with the meteor-stream, is entirely and at once dismissed by the 

 note of the more correct position of that comet's radiant -point. 

 The error of the radiant-place was noticed immediately after 

 the presentation, but not in time to jDrevent its publication in 

 the paragraphs of the Report of the j^ear 1878. The correction 

 which the above passages required was accordingly pointed out 

 in a 'Report on Meteoric Astronomy during the year 1878,' pre- 

 sented to the Royal Astronomical Society in February, 1879 

 (' Monthly Notices,' vol. xxxix. p. 294). Dr. J. L. E. Dreyer, of 

 the Dunsink Observatory, Dublin, who has devoted much atten- 

 tion to the orbit of this comet, has noticed that the true astro- 

 nomical place of its meteor radiant-point (which he gives at 

 27° 51' + 48° 24') is in pretty good agreement with a meteor sys- 

 tem nearly contemporaneous with the Perse'ids, noted by Schmidt
