The direction of the wind is indicated by the number of the point of the compass, reckoning N. := 0, E. = 8, S. = 16, W. = 24. The 

 motion of the three strata of clouds, Sc. (scud), C.-s. (cirro-stratus), and Ci. (cirrus), are indicated in a similar manner. 

 . Jan. 29"i 17'^. The anemometer has been partially frozen, its indications are therefore not trustworthy : the pressure of the wind has not 

 been more than 0-2 lb. during the night.
