The direction of the wind is indicated by the number of the point of the compass, reckoning N. = 0, E. = 8, S. =16, VV. = 2i. The 

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



May 13 d 20''. At 20 h m the lowest current of scud was just distinguishable to E. ; at 20 b 12 m it covered the whole sky, the wind 

 changing at the same time from NW by N. to NE by N. At 20 1 ' 18" the dry thermometer read 50°-0, and the wet 48°-3 : at ^'i' 1 30°\
