differed little from others at the coast, ihe 



readings could not be taken simultaneously, and the differenceSj being 

 less than the daily range of the instruments, were too small to permit any 

 reliable deduction to be made, or indeed to be at all accurately measured. 

 It can be at most but a few feet higher than the ordinary sea-level, 

 its surface being slightly depressed along the northern side, — in the 

 Sindree basin, — between Putchum and Kui-reer and near Adeysur.

presenting all three primary colors and numerous varieties of their 

 compounds. Owing to the oxides of iron, red and yellow prevail ; but in 

 some places these are mixed with pale lavender, blue and purple tints, and 

 contrasted with intense black or the pm-est white ; and when any vegeta- 

 tion adds some green, the brilliancy of the effect becomes very striking. 

 As a rule, the country has warm sienna tints, with red, purple or 

 black rocks pretty nearly always close at hand ; while the gray, purple or 

 orange hills are often varied by patches of white strongly reheved 

 against the adjacent sombre color of some mass of intrusive or overlying 

 trap.

 would seem to have been known to the ancients, and has been described 

 more or less minutely by many writers, including MacMurdo, Burnes, 

 Lyell and Grant.
