168 REMARKS ON THE PRECEDING PAPER, 



of the eastern portion of New South Wales ; and I think it was the 

 first attempt of the kind bearing on the wide area often visited 

 by such atmospherical derangements. As this account attracted 

 some notice, I commenced a series of papers on ^1 the 

 general topics of Meteorology, which were published in the 

 Sydney Herald in that year, 1842, in which, among other things. 

 I proposed to show that our Eastern Australian storms revolve 

 from left to right, and that the conflict of opposing winds is the 

 principal agency employed. I will quote a few remarks to show 

 how far Mr. Jevons's notion of monsoon-like winds and the 

 easterly set of the atmosphere alluded to by Mr. Tebbutt, were 

 anticipated by me 22 years ago, in connection with the South 

 and East Coasts of what was then altogether New South Wales. 



" In Bass's Strait a sort of monsoon prevails at certain periods 

 of the year, the wind blowing from the east for a time, though 

 generally from the westward at the other season ; and so power- 

 ful is the westerly wind that the trees upon Kent's Group point 

 to the east. 



" Beyond this, the great westerly circuit winds which travel 

 round the earth have their full influence, affected only by the 

 great southerly currents of air which sometimes as well as the 

 northern ones produce derangements in the ordinary phenomena 

 of the winds. 



" It may be assumed, therefore, that as easterly and southerly 

 winds are the most prevalent on the east side of the dividing 

 mountains ; so on the south-west side of these ranges the pre- 

 valent winds inland ought to be . from westerly points. Such is 

 the case, for there is direct evidence to show that the south- 

 westerly winds blow over the land from about the Gulf of Alexan- 

 dria to the Blue Mountains ; and north and north-westerly from the 

 N. W. interior to the Blue Mountains, the least violent of them 

 becoming west winds when they reach the mountains, and des- 

 cending into the seaward country to the east as west winds, 

 yet slightly deflected according to the passes through which 

 they descend. 



" The course of both N.W. and S.W winds seems to be de- 

 fined pretty accurately in the above statements as circuit winds 

 meeting somewhere about 147 and 150 E., and about that point
