3 REMARKS UPON METEOROLOGY. 



county of Lancaster, the storm, if proceeding from the 

 W, will first be felt m this place, then it will recede to 

 the coast of Wales, then to Anglesea, the Irish Chan- 

 nel, &c, until the equilibrium be established. But in 

 the storm of yesterday probably the contrary course 

 would be observed ; the current being formed by an abso- 

 lute increase of the volume of the atmosphere, it will push 

 forwards like a current in any other kind of fluid, and will 

 abate in proportion as the addition to the bulk of the atmos- 

 phere abates. If we pursue this idea so far as to suppose, 

 that storms from a \V point originate from the first, and those 

 from an E point from the second of these causes, we may 

 perceive why the former are more sudden in their com- 

 mencement, are preceded by greater indications of common 

 tion in the atmosphere, are attended with greater variations 

 of the barometer, are more squally in their progress, more 

 partial in their extent, and generally of less duration. 



I shall not think it necessary to proceed any farther with 

 the remarks upon my diary, as I conceive, that I have given 

 enough to afford a complete illustration of my ideas on the 

 subject. It is evident, that the first object is to obtain a

atmosphere, to notice the periods ot their commencement 



and duration, and the connection which they have one to the 

 other. The second great point is to invent some method by 

 which these changes may be accurately recorded ; and it 

 was here that I experienced the greatest difficulty, and that

terms that I have employed will be thought very uncouth; 

 and I have not unfrequently endeavoured to improve them, 

 by forming a nomenclature upon scientific principles. 1 how- 

 ever finally determined to postpone the attempt, as I found 

 it impossible to construct a nomenclature without involving 

 in it more or less of hypothesis; and although it is difficult 

 for any one to have thought so much as I have done upon 

 the subject of meteorology, without forming an hypothesis, 

 yet I do not consider mine as at present sufficiently mature 

 to meet the public eye. It appeared therefore more advisable, 

 not to attempt any thing like a methodical nomenclature, un- 

 til there was a probability of its being founded upon well esta-
