I ON A PIECE OF CHALK [1868] If a well were sunk at our feet in the midst of the city of Norwich, the diggers would very soon find themselves at work in that white substance almost too soft to be called rock, with which we are all familiar as "chalk." Not only here, but over the whole county of Norfolk, the well-sinker might carry his shaft down many hundred feet without coming to the end of... more...

It is an usual and a commendable practice to preface the discussion of the views of a philosophic thinker by some account of the man and of the circumstances which shaped his life and coloured his way of looking at things; but, though Zadig is cited in one of the most important chapters of Cuvier's greatest work, little is known about him, and that little might perhaps be better authenticated than... more...

That application of the sciences of biology and geology, which is commonly known as palaeontology, took its origin in the mind of the first person who, finding something like a shell, or a bone, naturally imbedded in gravel or rock, indulged in speculations upon the nature of this thing which he had dug out—this "fossil"—and upon the causes which had brought it into such a position.

I. ADMINISTRATIVE NIHILISM. (AN ADDRESS TO THE MEMBERS OF THE MIDLAND INSTITUTE, OCTOBER 9TH, 1871.) To me, and, as I trust, to the great majority of those whom I address, the great attempt to educate the people of England which has just been set afoot, is one of the most satisfactory and hopeful events in our modern history. But it is impossible, even if it were desirable, to shut our eyes to the... more...

CHAPTER I. EARLY LIFE: LITERARY AND POLITICAL WRITINGS. David Hume was born, in Edinburgh on the 26th of April (O.S.), 1711. His parents were then residing in the parish of the Tron church, apparently on a visit to the Scottish capital, as the small estate which his father Joseph Hume, or Home, inherited, lay in Berwickshire, on the banks of the Whitadder or Whitewater, a few miles from the border, and... more...
