212 REPORT — 1875. 



few months later in Zsadany in Hungary, will be found in a review of such 

 occurrences, and of the principal investigations that have been made with 

 regard to them during the past year, in the notices on Meteorites (Part I., 

 pp. 240, 243) at the end of this Eoport. 



The August Meteor-sliower in 1874. — The shower was partially observed 

 near Chelmsford, Essex, by Mr. H. Corder, with the following results as to 

 the numbers seen ; but the cloudy state of the sky prevented any appearance 

 of the shower from being visible on the night of the 10th.

On the night of August 11th, with a favourable view of the sky, Mr. 

 Corder, watching alone (as on the former nights), counted the following 

 numbers of shooting- stars in the half-hours ending at

Three of these meteors were as bright as Jupiter, the brightest appearing 

 at 10'' 3.5" P.M. in Cassiopeia ; 82 left streaks, including aU of the 1st, 

 nearly all of the 2nd, and a great proportion of the 3rd mag. shooting-stars. 

 Twelve meteors were unconformable, or obviously not directed from the 

 radiant-point in Perseus, and the length of path varied from g° to 30° (in 

 the case of a large one overhead at ll'' 5" p.m.). The prevailing colour of 

 the meteors from Perseus was orange. Their general centre of divergence 

 was near the cluster ^ in Perseus, extending also to Cassiopeia. On 

 August 2nd most of the meteors diverged from e Pegasi ; and on the 6th the 

 points of radiation were very various, belonging chiefly, however, to the 

 shower from Perseus. 



Mr. J. E. Clark obtained a view of the shower at York on the night of 

 the 10th, mapping 40 meteor-tracks between lO** 7™ and ll'' 55™ p.m., and 

 together with Mr. E. Grubb counting the following numbers in the successive 

 haK-hours of the watch ending at
