Mr. E. W. BiNNEY referred to the existence of similar 

 striations ou the Carboniferous limestone of Great Ormes 

 Head, where the groovings were found to range northward, 

 or outwards from the mountains of the interior. He also 

 noticed the distribution of the Shap granite, blocks of which 

 he had lately seen on the high Silurian and Carboniferous 

 ranges to the south and south-east of Shap Fell. 



Mr. Brockbank stated that, on the high lands of York- 

 shire and Derbyshire, he had observed erratic blocks which 

 could be traced to their northern sources. 



Mr. Hull, in conclusion, stated that it had been abundantly 

 shown, by the collection of a large number of facts, that the 

 direction of the erratic blocks of the Drift period was from 

 north to south, so that there must have been some pre- 

 dominating influence in operation, either prevalent winds, or, 

 more probably, oceanic currents, tending to impel southward 

 the icebergs and rafts which were the vehicles for the 

 transportation of the erratic boulders and pebbles. 



A Paper was read by Mr. Baxendell, F.R.A.S., ^' On 

 the Influence of the Seasons on the Rate of Decrease of the 

 Temperature of the Atmosphere with Increase of Height, in 

 different Latitudes of Europe and Asia." 



The determination of the laws of the distribution of heat 

 in the different strata of the atmosphere under various 

 circumstances of season, locality, direction of the wind, baro- 

 metric pressure, &c., is one of the most important, and, at the 

 same time, one of the most difficult problems which can 

 encase the attention of the meteorologist. Notwithstanding 

 the labours of many able meteorologists and physicists, 

 several points of considerable importance to the future pro- 

 gress of meteorology are still involved in doubt and obscurity ; 

 and the necessity for further inquiries has been so generally 

 acknowledged, that at the late meeting of the British Asso- 

 ciation in this city, a grant of i>200. was renewed to defray
