The above Table, which has been compiled with great care from manuscript records in my 

 possession, will be found valuable by enabling us to compare the climate of Milwaukee with 

 that of other places. It will be seen that the general mean temperature, deduced from all the 

 observations, is 46°.18 ; that the coldest year was 1856 (41°. 57), differing 8°. 37 from the 

 warmest year 1845 (49°. 94) : the coldest month is January (22°. 76), though in six eases 

 February was the coldest. January, in 1857, was the coldest month known since the first 

 settlement of the place, the mean temperature being only 7|°. July is the warmest month 

 (70°. 21) : June, in 1854, was the warmest month. The winter and spring of 1845 were the

most moderate in eighteen years ; the winter of 1856 and the spring of 1857 were the coldest. 

 The hottest summer, 1854, was followed by the mildest autumn. It will be noticed that no 

 extreme of temperature, either of heat or cold, indicated by the table in antique figures, has 

 occurred since 1857. If we take the mean annual temperature of five years together, it will 

 be found that the terms ending with 1858 (46°. 71), and with 1863 (46°. 36), were very near 

 the general mean, while the term ending with 1857 was the coldest (42°. 56) ; thus indicating 

 that there may be some truth in the popular theory of cold and warm terms of years.
