dualU'' passing, or becoming converted into aiiother species; 

 and what is their relation -with respect to the state and di- 

 rection of the wind. To enter into a fnll detail of this sub- 

 ject would alone occupy a long dissertation, I shall merely 

 take occasion to illustrate some parts of it in the explana- 

 tion which I shall give of the specimen of my journal. In Appearance of 

 the account of the state of the weather on the 1st of Sep- ^istantobjectsf. 

 tember I have mentioned the appearance of distant objects. 

 Those to which I refer ase the mountains, which are seen 

 in different directions from the vicinity of Liverpool. To 

 the W and SW we have a long line of hills situate in the 

 counties of Flint and Denbigh, from 20 to 30 miles dis- 

 tant, and beyond these the summits of some of the Caer- 

 narvonshire mountains are visible. To the S we have the 

 high lands in the SW of Cheshire, and beyond these are 

 occasionally seen the peaks of the Montgomeryshire moun- 

 tains. To the E and SE is the range of'-.hills that separates 

 the counties of York and Lancaster, and also those in the 

 N of Derbyshire and Staffordshire. It is not in many si- 

 tuations, that the spectator has an opportunity of setting all 

 these objects from one point of view, nor is it often that the 

 state of the atmosphere renders them all visible at any one 

 time; but it will be perceived, that our situation is very- 

 favourable far observations of this kmd. Distant objects 

 vary as to their apparent size, their distinctness, and their 

 cok-ur. 



Lender the title of particular states of the atmosphere I State of the 

 mean to designate some phenomena, which are sufficiently ^^™**^^ ^^°' 

 obvious and characteristic, but the immediate cause of 

 which is doubtful.^ I have observed in my notes, that the 

 afternoon of the 1st of September was transparent, and I 

 shall endejjvour to describe what I mean to designate by 

 this term. A transparent condition of the atmosphere sel- 

 dom lasts for more than a few hours, and these generally 

 before sunset. The sky is either clear, or if there be any 

 clouds, they consist of fine lines lying parallel to each other, 

 or of irregu'ar tufts in the upper parts of the sky, or of 

 sqnall, round, spotted clouds near the iiorizon. What how- 

 ever give- rhf character and name to this kind of day is the 

 peculiarly beautiful appearance, which moderately distant
