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. 

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

 Jan. 20* 3^ 40™. Heavy showers of snow and sleet with strong wind.
