Deo. 21, 1890, Annual Meeting.— Dr. Tripe 

 read the report of the council. Among the 

 investigations carried on by the society are 

 the following: the organization of a large 

 number of meteorological stations, the ob- 

 servations fi'om which are examined and 

 reduced by the staff, and printed in the 

 Meteorological Record; the regular inspec- 

 tion of these stations by the assistant secre- 

 tary ; the collection and discussion of pheno- 

 logical observations; and an inquiry into the 

 thunder-storms of 1888 and 1889. An exhi- 

 bition of instruments is held annually in 

 March. During the year a complete cata- 

 logue of the library, extending to 222 pages, 

 has been compiled and published. 



Ordinary Meeting. — R. H. Scott, Note on 

 a Peculiar Developmen,t of Cirrus Cloud ob- 

 served in Southern Switzerland; W. F. 

 Badgley, Some Remarks on Dew. These 

 are notes on observations which were made 

 to discover whether all dew is deposited 

 from the air, or if some also comes from the 

 earth and plants, and also what quantity is 

 formed during the year. The conclusions 

 which the author deduces from his observa- 

 tions are (1) that the earth always exhales 

 water- vapor by night, and probably a greatei' 

 quantity by day; (2) that the quantity of 

 water- vapor given off by the earth is always 

 considerable, and that any variation in the 

 quantity is mainly due to the season of the 

 year; (3) that the greater part of the dew 

 comes from the earth- vapor; and (4) that 

 plants exhale water- vapor, and do not exude 

 moisture. The total quantity of dew collected 

 on the author's gi'ass-plates in the year was 

 1.6147 inches.
