METEOROLOGY OP 18G0.

So that in the year 1830, the 24th and 25th December were more remarkable for 

 the severity of the cold, as shown in their mean temperatures, than in the present 

 instance ; but there is no instance of so low temperatures in December back to 

 1814, as those shown on Christmas-day and on the 29th day. The previous 

 instances of low temperature in the neighbourhood of London are as follows, 

 going backwards and confining myself to December : — 



1855, December 19, the temperature was as low as 12° 



1855, February 19,

The low temperature of December 25 was general over the country, but more 

 severe in some places than in others. The following are the readings by tested 

 instruments made for the most part by Messrs. Negretti and Zambra, and 

 examined before use by Mr. Glaisher, and spread over the country. They are 

 arranged in order, starting from the place of highest temperature : — 



St. John's College 

 (Hurstpierpoint)... 3*0 



Helston 32-0 Alnwick 120 



Guernsey 30-0 Clifton 11 1 



Truro 260 i Regent's Park 109 



Ventnor 240 Battersea 10-5 



Pembroke 220 Aldershott 100 



Fairlight 200 Hartwell Rectory ... 100 



Osborne 19'0 Harrogate 9 - 5 



Worthing )8"0 . Ben Rhydding 8"5 



Elgin 170 ! St. Paul's Parsonage 8*5 



Little Bridy 162 j Allenheads 83 



Liverpool 162 , Greenwich 8 -

Exeter 13-5 Gt. Berkhampstead. 4 - 



Asplev 13'5 Cardington 3'0 



■Whitehall 127 Bywell 35 



And if these be laid down on a map it will be found that the temperature on 

 the south coast was about 20" ; and it gradually became less proceeding north- 

 wardS: It was about 7 in the neighbourhood of London. It was about 1°, in a 

 line across the country from Gloucester, through Oxford to the east coast. It 

 was below zero, between the latitudes 52° and 53". from Wales to the east 

 coast ; and it was above zero at all places north of 54° ; about 16" on both the 

 ei^t and west coasts, and of somewhat less temperature inland. It was 12° at 

 Alnwick.
