146 Hourly Meteorological Observations. 



8. The velocity of the wind may be easily ascertained by 

 measuring the distance to which a light body, such as a fea- 

 ther or a piece of paper, is carried in any number of seconds. 

 Its direction may be found by a wind-vane, or by the smoke 

 of a chimney. The existence and direction of currents in the 

 higher regions may be detected by the motions of the clouds. 



The remaining columns of the table must be filled up ac- 

 cording to the judgment and knowledge of the observer. Mr 

 Howard's nomenclature of clouds should be used by those 

 who are acquainted with it. Halos, rainbows, the Aurora Bo- 

 realis, the depth of the blue colour of the sky, and the colour 

 of the clouds at sunrise and sunset, will naturally attract the 

 notice of every observer. 



To those meteorologists who have sufficient leisure, and the 

 means of performing such experiments, we would recommend 

 the use of kites or of balloons for ascertaining the temperature 

 and state of the upper atmosphere. The Earl of Minto has ob- 1 

 tained several very interesting results by the use of balloons, 

 and by proper precautions has found them perfectly manage- 

 able. 



The following is an alphabetical list of the observations on 

 the 17th July which have already been received, and there is 

 reason to expect as many more, as few of the foreign ones 

 have yet arrived. 



It is greatly to be desired, that those who have so well be- 

 gun this interesting series of experiments, will continue them 

 on the 15th January, and also in subsequent years.
