 29, ]jp. /> 10-532). — A detailed summary is given of observations during the summer 

 (June, July, and August) of 1903 at 42 different places in Tunis on pressure, tem- 

 perature, rainfall, humidity, cloudiness, direction of the Avind, and miscellaneous 

 phenomena. The average temperature for the summer of 1903 is compared with

Meteorology of British Guiana, J. B. Harrison (ii^j/. Agr. Work Bot. Gard. 

 [British, Chiiana'], 1903-3, pp. 3-5). — A record is given of the rainfall and duration of 

 sunsliine at the government laboratory, Georgetown, during the 18 months ended 

 June 30, 1903. The record includes not only measurements of the rainfall, l)ut its 

 contents of chlorin and of nitrogen in the form of ammonia and nitric acid. The 

 rain which fell during the period referred to contained 244 lbs. of chlorin, equal to 

 402 lbs. of common salt per acre, and 4.67 lbs. of combined nitrogen, equivalent to 22 

 lbs. of ammonium sulphate. For the year ended June 30, 1903, the figures were 3.1 

 lbs. combined nitrogen and chlorin, equivalent to 205 lbs. of common salt per acre. 

 The total rainfall for the same perioil was 98.9 in.
