Remarks on the preceding paper, made at the Meeting of 7th 

 September, 1864, by 



THE REV. W. B. CLARKE, M.A., F.G.S. &c., V.P. 



IN the paper just read there are 31 distinct propositions or state- 

 ments, with an appeal to the public, and especially to this 

 Society, to aid in researches such as those in which the author 

 of that paper is so usefully engaged. 



It may not be, perhaps, impertinent to mention this appeal 

 before I proceed to notice the other very interesting subjects 

 discussed by Mr. Tebbutt. There have been several writers 

 in this colony already on the science of Meteorology or on some 

 of its most important branches. Count Strzelecki, in his "Physical 

 Description of New outh Wales and Van Diem en's Land, published 

 in 1845, entered on the Climatology of these colonies, and 

 discussed the nature of the atmospheric currents from his own 

 personal observations. He gives a table of monthly currents 

 contrary in direction to surface winds ; attributing some of the 

 observed phenomena to increase or decrease of the Sun's declina- 

 tion, showing that a cold current moves frequently between two 

 warmer currents entirely by virtue of its volume. 



He further shows from his own observations, that at Port 

 Phillip the rule adduced by Mr. Tebbutt for Adelaide obtains, 

 viz. : polar winds prevail in summer ; but he appears to oppose 

 Mr. Tebbutt's solution of a rise of the equatorial current, 

 stating that there is no proof of this from observation. Further, 

 he shows that the rule stated for Port Phillip and now for 

 Adelaide, is not maintained either in Tasmania, Port Jackson, 

 or Port Macquarie, of which in the former the equatorial pre- 

 vails both in summer and in winter, and in the latter two 

 localities the winter is distinguished and not the summer by 

 polar winds. He infers that such variations must depend on 

 something more than a local cause, and probably belong to the 

 influence of monsoons and winds existing within a certain dis-
