 at 11 P.M. — This night was everywhere noticed to be peculiarly 

 hot and close. 



July 29. — Before sunrise the great black mountainous cumu- 

 lostratui below rows of cirrostratus, &c. had a beautiful effect 

 after the rain. The Thermometer, which continued above 70 

 all last night, was 65° at sunrise. Afterwards it became cooler, 

 with much cloud and wind. Mr. Sadler's balloon went from 

 London to Chelmsford in less than an hour. 



July 30. — Fair day, with cumuli and cirri. Gale from SW. 

 and fine moon-light evening. 



Jiily 31. — Clear and thin clouds in the morning. Through 

 the day there was a haziness, but it was fair with cirri and cti- 

 muli. At night cirroslratus and cirrocumulus by moonlight had 

 a fine mottled appearance. The cirrocumulus appeared the 

 most elevated, and had that clear and definite appearance which 

 I noticed so often to accompany fine warm weather in summer, 

 and which is quite different from the loose and scattered features 

 between many common showers, as well as from those dense, 

 compact and closdy collected aggregates which precede thun- 

 der storms. ,
