in the published catalogues of Heis, Schiaparelli (1872), Weiss, and 

 Konkoly, These include many thousands of paths observed during 

 the period from August 6th to 12th, and such of these as were obvi- 

 ously directed from radiant points situated eastward of Perseus were 

 projected on the star-maps prepared by Professor Herschel for the 

 purposes of the Luminous Meteor Committee of the British Associa- 

 tion. In all 762 meteors were thus utilized, and they gave distinct 

 evidence of the positions of a number of active streams in Auriga and 

 Camelopardus, some of which were previously observed by Heis, and 

 many of them have been confirmed by the writer during the last five 

 years. The following list embraces the chief radiants thus deduced :

The relative positions of these showers are depicted in the diagram 

 (Fig. 3), where the more prominent displays of the group are represent- 

 ed by deeper circles than the minor. Some of the latter can not yet 

 be regarded as certainly established, inasmuch as they rest on slender 

 materials. 



Heis devoted much attention to the meteors of the August period 

 during more than forty years (1833-'75), and in his extensive " results," 

 published in 1877, gives the following as the chief radiant points for 

 August 9th-llth :

But, in addition to these, there are a large number of radiants scat- 

 tered over the sky, especially in the eastern quadrant. One of the 

 most notable of these proceeds from the eastern extremity of Aries 

 (44 -I- 25), and supplies some bright meteors in the morning hours ; 

 but the most conspicuous shower discovered east of Perseus at this 

 epoch lies in Camelopardus, and in the diagram (Fig. 4) a number of 

 its meteors, falling among the stars of Ursa Major, are reproduced
