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

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



Jan. l d 20 h . The wind has been blowing about 0'2 or 0-3 lb. for some time, but no pressure has been indicated by the anemonetcr, 

 probably from the vane being frozen up.
