A CATALOGUE OF OBSERVATIONS OF LUMINOUS METEORS. 297 



The particulars of the observations of the meteoric shower at Birmingham 

 are summed up by Mr. W. H. "Wood in the following remarks : — 



" Colours of the meteors bluish white, yellowish white, pale green. The 

 present display exhibits a decHiie below^ the average of the past ten years in 

 hourly numbers and apparent magnitudes, which differ strikingly from the 

 corresponding data of the August meteor-shower in ISfiS (see the Report for 

 that year, p. 381). The proportion of small meteors will be found to have in- 

 creased twofold, and of the more conspicuous ones to have diminished in the 

 ratio of about 3:5. A curious feature is presented by the fact that the per- 

 centage number of meteors diverging from tj Persei in the present year is 

 the same as that of the meteors radiating from the same centre in the year 

 1868, and that the percentage numbers of meteors from y Persei and e Cas- 

 siopeise are, as in that year, equal to each other, and only less by four than 

 in the year 1868. The frequency of meteors from the radiant-points in 

 Pegasus is this year a little in excess. The data furnished by this year's 

 observations regarding the other coexisting radiant-points are insufficient 

 for comparison with those of former years. There were no sporadic meteors." 



Up liU the 8th of August the number of meteors observed during the 

 month, in Piedmont, exceeded 1.500, of which Mr. Denza will publish a 

 description and chart in the ' BuUetino ' of the Observatory of Moncalieri. At 

 Moncalieri itself the following numbers of meteors were observed on the 

 nights of August

Tlie sequel of the remaining observations of the August period at Mon- 

 calieri, and at other places in Italy, will be published in the Monthly 

 Bulletin of that Observatory. Many of the meteors radiated from Cygnus, 

 and from Cassiopeia. (Letter of F. Denza to Mr. 11. P. Greg.)
