Pagina 60 - There they stood, ranged along the hill-sides — met To view the last of me, a living frame For one more picture ! in a sheet of flame I saw them and I knew them all. And yet Dauntless the slug-horn to my lips I set And blew " Childe Roland to the Dark Tower came...
Pagina 219 - Now go and smite Amalek, and utterly destroy all that they have, and spare them not ; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.
Pagina 66 - Heroes who despise the Dutch, And rail at new-come Foreigners so much ; Forgetting that themselves are all deriv'd From the most Scoundrel Race that ever liv'd, A horrid Crowd of Rambling Thieves and Drones, Who ransack'd Kingdoms, and dispeopled Towns...

Pagina 546 - The impossibility of separating the nomenclature of a science from the science itself is owing to this, that every branch of physical science must consist of three things: the series of facts which are the objects of the science, the ideas which represent these facts, and the words by which these ideas are expressed. Like three impressions of the same seal, the word ought to produce the idea, and the idea to be a picture of the fact.
Pagina 292 - The more I learn by heart the more clearly do I see images of my pages. Even before I can recite the lines I see them so that I could give them very slowly word for word, but my mind is so occupied in looking at my printed image that I have no idea of what I am saying, of the sense of it, etc. When...
