Dr. Geo. Engelmann read a paper " On the Meteorology of 

 the Month of January," as follows : 



The unusual meteorological conditions of December last, of which I 

 gave an account a month ago, have continued through January. The last 

 month of last year was the warmest December we have had in forty jears. 

 The past January was one of the five warmest Januaries in the same period. 

 The mean temperature was 39.4°, while the usual mean for that month is 

 31.5°. January, 1848, had the same temperature, and was followed by a 

 February and a March warmer than usual. January, 1842, was warmer, 

 and the following four months were warmer than the average. January, 

 1845, and 1858, had a mean temperature of 40.5°. In 1845 the three suc- 

 ceeding months had a temperature above the average, but the mild Janu- 

 ary of 1858 was preceded by an equally warm December, and followed b\' 

 a bitter cold February with a mean temperature of 27.2° — over 13° lower. 

 Thus, in the four years mentioned, three times a warm January was fol- 

 lowed by a warm February and March, and once the reverse was true. 



But what of the unusual quantity of rain which fell last month? It is 

 commonly thought that mild winters, in which of course southerly winds 

 prevail, are also wet winters; but what are the facts? Three of the above 

 mentioned mild Januaries ('42, '45 and '48) had, the first less than i inch, 

 the others less than 2 inches of rain, all three less than the average 2.13 

 inches, and only the January of that year ('58) which was followed by a 

 very cold February, and the January just past, have had more than the 

 average amount of rain, the former 3.42 and the latter 4.44 inches : and
