2. In the southern hemisphere, owing to the large proportion which sea bears to land, the temperature does not agree with that of corresponding latitudes in the northern hemisphere, but is generally found to be cooler by two or three degrees. Thus the temperature of Port Lincoln in 35°, South, may be expected to agree with that of places on the sea-coast between 37° and 38° of North latitude.

3. Except where the land is gaining on the sea by the deposits of great rivers, land close to the sea is generally less fertile than land some way removed from it. This is peculiarly the case in every known part of extra-tropical Australia. Here, it seems, the sea is almost universally separated from land of superior fertility by a stripe of very poor land, commonly of sand, bearing only stunted brushwood, and varying in breadth from two or three, to twenty or thirty miles.

Very fine land close to the sea, where the sea is not touched by a range of high land, is a rare exception to the general rule of sameness already noticed.

Hence we are never to presume from the known ste-
