174 REMARKS ON THE PRECEDING PAPER, 



the set of the warm ocean current from the N.E., which has, 

 I am persuaded, a great deal to do with the rains which have so 

 often fallen upon our shores, and especially during the late 

 terrible season of floods. 



I watched the state of the ocean during several of our late 

 gales. It was everywhere, within reach of my sight, smoking 

 with fog which, drifting in with the rain from the surface of the 

 ocean current, caused that superabundant moisture which was 

 twice observed on smooth walls and metallic surfaces that 

 streamed with it, owing to the sudden condensation of the warm 

 vapour. The high thermometer and the increase of Ozone 

 which is characteristic of sea winds, both show how much those 

 periods were affected by the influence of equatorial currents. 



A storm of striking features, in February, 1863, was noticed 

 by Mr. Tebbufct and registered in the Empire, which showed a 

 progression to southwards. 



Very little was wanting to the collected data, to give a 

 complete history of that storm. Fortunately, I was at the time 

 in a position to supplement Mr. Tebbutt's observations. I was 

 then to the westward of the Bell River, about 260 or 270 miles 

 W. by N". of Windsor, and about 25 miles from the head of the 

 Bogan. Having a barometer and thermometer with me, I was 

 enabled to notice what took place ; and one remarkable fact 

 preceding the gale was, that we had the regular sea breeze 

 on the evening before, which in all probability came in through a 

 distance of 300 miles from the neighbourhood of Port Macquarie. 

 I have frequently felt the sea breeze under the Liverpool Range. 

 As there is no land much higher than 4000 feet between the two 

 points, the sea breeze must at least have had about the same 

 vertical thickness. In Maneero I have found it generally not 

 more than that. As I was observing the western edge of the 

 gale, the diameter of it must have been at least about 300 miles. 



Another gale that of April and May, 1864 is noticed by 

 Mr. Tebbutt ; and by the periods of minimum barometrical pres- 

 sure and changes of wind, this was a gale from the northward. 



Now, I would call attention to a fact I alluded to when I began, 

 the wide area over which ordinarily the atmospherical phenomena 

 are persistent.
