 bification, afterwards fair, cumuli and c/mmlostrati, with a 

 disposition above to cirrocinnulus. By sunset the under 

 surface of amass of a kind oi cumulostratus refracted a rich 

 crimson light, from which hung golden dependent frino-es; 

 the sky beneath of a fine yellow ; clear and cool night. 



July 13. — N.E. Clear early, then cumuli formed; small 

 and fleecy specks by degrees became larger; neighbouring 

 ones were lost, and the c«7«m/j becauic large, but ili-de(incd; 

 some higher masses of cirrostruius and cirrocumulus ill- 

 defined.

 rocumulus ; wind S. E. In the afternoon a vimhus came 

 up from W.N.VV., after which the wind blew from that 

 quarter; clear night.

 ramified in various directions; those which appeared the 

 lowest were more comoid, and some extended their fibres 

 in every direction ; air dry, and wind W.N. W. Towards 

 evening the cirri became more confused, passed to cirro- 

 cumulus, and in some places to cirrostraius, through which 

 the moon appeared obscurely, and predicted rain ,• but the 

 night became tolerably fair; wind westerly.

 passing clouds from the north at 6^ p.m.

 of nimbiform appearance; in the evening it approached to 

 the nature of cirrostraius, and exhibited itself in fine 

 streaks, like the grain of polished wood, and in rows like 

 the mackerel back feature well known by tlial name. Cw 

 muLi occasionally thickening into almost cumulostratus 

 also prevailed; some tendency also appeared to cirrocumulus.
