January. — The year 1867 commenced with severe cold. The 

 1st of January was an extremely cold day throughout England. 

 At Wakefield, the thermometer fell to 5° Fahrenheit, or 27° be- 

 low freezing point. The severest snow-storm known in London 

 for some years began on January the 2nd. The lowest daily 

 readings of the thermometer at Greenwich, January 1-5, were — 

 January the 1st, 21-8°; January the 2nd, 15°; January the 3rd, 

 10*4° ; January the 4th, 7'7°. The mean temperature of the 

 month was 13-5°, or 23° below the average. It appears from the 

 records of the daily temperature at Greenwich, that during the 

 last fifty years only four days have had a lower mean tempera- 

 ture than January the 4th, 1867. In 1816 the mean tempera- 

 ture of February the 9th was 12-6° ; 1823, January the 19th, 

 13-4°; 1838, January the 20th, 10-7°; 1841, January the 8th, 

 12-8°; 1867, January the 4th, 13-5°. 



The four days (January 6-10) which followed this great frost 

 were remarkable for their high temperature, accompanied by low 

 atmospheric pressure. On the 11th another frost set in, and 

 continued till the 22nd.
