ME. G. S. BEADY ON THE 



4. That the winter mouths are all much warmer, aud every 

 month in the year somewhat warmer than formerly. 



There can he no kind of doubt, I think, of the perfect correct- 

 ness of his deductions, and the soundness of his data ; moreover, 

 he proves his figures by the quotation of general memoranda of 

 the weather during the years in question, which corroborate the 

 instrumental records ; and I think Mr. Glaisher clearly and in- 

 contestably establishes his point. 



The only question is, can any local circumstances affect the 

 mean temperature of Greenwich ? Is it not possible that a good 

 deal may be due to the increase of smoke and vapour, preventing 

 the radiation of heat ; and that even the exceedingly increased 

 traffic and movement on railways on the Thames and neighbour- 

 hood may cause an appreciable amount of heat ; much of it also 

 created, as it is, by steam power ? 



If there be no cause of this kind, the fact is indeed a most 

 extraordinary one. 



I applied to a very high scientific authority in Paris, to know 

 wh ether any such change has been observed in France, during 

 the same period ; but have received no information.

Mrs. Eoddam remarks — The forest trees shed their leaves in 

 a very singular manner this season. In many instances the south
