Phillip, the author infers their similarity in age. In concluding,

none varying more than two points from north and south. He ^.lso 
cites the opinion of Capt. Sturt, that one vast desert plain 
stretches from the great Australian Bight to the Gulf of Carpen¬ 
taria; and observes that the only great extent of country unac¬ 
counted for, is on the north-west side, where the range between 
Cambridge Gulf, and Buccaneer’s Archipelago may rise into some 
importance in the interior.— Athenaum.
