THE CLIMATE OF LORD HOWE ISLAND. 
By H. C. Russet, B.A., c.M.G., F.B.S. 
[Read before the Royal Society of N.S. Wales, October 2, 1895.) 
In working up the temperature records of this colony for a map, 
which I have made with a view of showing for each square degree 
of the colony, the mean annual shade temperature, the tempera- 
tures of spring, summer, autumn, and winter, as well as the highest 
and the lowest shade temperature ever recorded there on any day, © 
I was very much struck by the mild climate of Lord Howe Island. 
Its surrounding currents of tropical water coming down from the 
north, no doubt keep the little island in a more equable climate 
than I anticipated, and I have brought the facts before you 
simply to place them on record, and to show by comparison with 
the mainland the advantages Lord Howe possesses in its climate, 
which may make it a sanatorium for those requiring a mild winter. 
The records at Lord Howe Island extend over eight years 
I have put with it, for comparison, the records at Sydney and on 
the New South Wales coast in the same latitude as Lord Howe 
Island.
