The amount of cloudiness appears to be very high; but as the ob- 
servations only embrace a period of eight months, perhaps they are 
not a fair representation of the climate. 
The average amount of rain in a period of 11 years, was 24°565

(3.) Annuaire Magnetique et Meteorologique de Russie, par A. T. 
Kurrrer, 1842. 4to. [The 7th of the Series.] 
In this imperial Annuaire, worthy of the Cesars, we find meteoro- 
‘logical. observations made every hour of the day, at St. Petersburg, 
Barnaoul, Nertchinsk, Catherinenburg, and Sitka; and observations 
made eight hours of the day at Zlatouste, Bogoslowsk, Lougan, and 
Peking; observations which are more valuable, as several of these 
places are situated in a quarter of the globe hitherto but little known. 
Most of these stations have also furnished magnetic observations. The 
following is a summary of some of the results for 1842.
