342 report— 1878. 



o£ questionable determinations of the meteor-showers themselves, rather 

 the appearance of being accidental coincidences than clear proofs of 

 real resemblance or of positive identity. The cases of the accordances 

 (noticed above, pp. 326 and 335) between the comet of 1870 I ?3 , and 

 the August Perse'id shower in 1871, and of the comet, 1825 II, S 

 ( — 0-115, Oct. 7th, 134° + 77°) with a briefly enduring meteor-shower, 

 noted by Mr. Denning on the nights of October 3rd and 4th, 1877, at 

 130° + 79°, are perhaps exceptions. Mr. Denning wrote that he never 

 noted a shower better than this rich one during the two nights that 

 its activity was at its maximum, and that in place and date of its 

 appearance, its agreement with those of the hypothetical comet-shower 

 was quite unexpected, and is practically perfect. This shower is un- 

 noticed in the accordance (No. 49), where the observation properly 

 belongs ; but when duly inserted and added there to the previous tokens 

 of resemblance to the comet which showers observed by Heis and 

 Denning are shown to present, it would be the best marked, and most 

 certainly verified accordance of any of the nearly positive and deter- 

 minate ordinary cometic correspondences which are recorded in the list. 

 Mr. Denning also communicates the following meteor-shower positions as 

 having escaped notice in some of the other accordances of the list 

 which are here briefly denoted by their reference Nos., the comet's node, 

 and the omitted meteor-showers.
