GENERAL STIMMAEIES. 



Mean temperature at 8 a. m. in December and January, at Middlebury, Ver- 

 mont, recorded by H. A. Sheldon. 



Newarh, New Jersey. — The following tables of temperature and rain at New- 

 ark, New Jersey, for "a series of twenty years, are from articles prepared, by 

 Mr. Whitehead, and published in the Newark Daily Advertiser. His records 

 ■of temperature are made only from self-registering thermometers, and half the 

 sum of the maximum and minimum of t ach day is taken for the daily mean, and 

 from these he derives the monthly and annual means. Some of the figures differ 

 from those in the newspaper, several typographical errors having been corrected 

 by Mr. Whitehead.
