The direction of the wind is indicated by the number of the point of the compass, reckoning N. = 0, E.=8, 8S. = 16, W. = 24. The 
motions of the three strata of clouds, Sc. (seud), C.-s. (cirro-stratus), and Ci. (cirrus), are indicated in a five manner. 
April 244 0" 40, It was found on trial that when the feather-vane was pointing from the north, its index pointed to NNE. ; the index | 
was setright; this error could have existed for a short period only.
