the application of algebra to geometry, he answered in the affir- 
mative, and immediately solved the following problem :—Given 
one leg of a right-angled triangle, and the excess of the hy- 
pothenuse above the other leg, to construct the triangle. He 
answered two or three problems relating to the maxima of num- 
bers and of geometrical magnitudes with ease, and took the 
fluxions, which were not difficult, correctly. When the age of 
this child is compared with his scientific attainments, we can 
look on him in no other light than as a literary phenomenon, 
who promises to become an ornament to one of the British Uni- 
versities, unless his progress should unfortunately be checked by 
indigence, or the vigour of his mind should he enfeebled by some 
sinister accident. Joun GouGH.

NEW SOUTH WALES. 
A discovery has heen made in New South Wales, which must 
materially affect the future advancement of that colony. “A 
river of the first magnitude” has been found in the interior, 
running through a most beautiful country, rich in soil, lime- 
stone, slate, and gcod timber. A means of communication like 
this, has long been anxiously searched for- without success, and 
many began to entertain an apprehension that the progress of 
colonization in New Holland would be confined to its coasts. 
Mr. Oxley, the surveyor-general, was sent out with a party in 
an expedition to the westward of the Biue Mountains, to trace 
the course of the lately discovered river Lachlan, and to ascer- 
tain the soil, capabilities, and productions, of the country through 
which it was expected to pass in its course tothe sea. Mr.Oxley 
left Bathurst on the 30th April 1817. He proceeded down the 
Lachlaa yntil the 12th May, the country rapidly descending
