In 1839 he left to enter the Corps des Mines. From the beginning of... more...

In my presidential address, which I had the pleasure of reading before this society at our first meeting this year, I called attention, somewhat hurriedly, to the results of a few of my experiments on induction, and at the same time expressed a hope that at a future date I might be able to bring them more prominently before you.

These latter, by reason of their peculiar form, present a great resistance, not only to the vertical blow of the pile driver (as it is indispensable that they should), but also to horizontal pressure when excavating is being... more...

PERIPLUS OF HANNO THE CARTHAGINIAN. I am not sufficiently Quixotic to attempt a defence of the Carthaginians on the western coast of Africa, or any where else, but I submit that the accusation brought against them by Mr. S. Bannister, formerly Attorney-General of New South Wales, is not sustained by the only record we possess of Hanno's colonising expedition. That gentleman, in his learned Records... more...
