"My bat-like thought-wings would beat painfully in that sudden searchlight," H.D. writes in Tribute to Freud, her moving memoir. Compelled by historical as well as personal crises, H.D. underwent therapy with Freud during 1933-34, as the streets of Vienna were littered with tokens dropped like confetti on the city stating "Hitler gives work," "Hitler gives bread." Having endured World War I, she was now gathering her resources to face the cataclysm she knew was approaching. The first part of the book, "Writing on the Wall," was composed some ten years after H.D.'s stay in Vienna; the second part, "Advent," is a journal she kept during her analysis. Revealed here in the poet's crystal shard-like words and in Freud's own letters (which comprise an appendix) is a remarkably tender and human portrait of the legendary Doctor in the twilight of his life. Time double backs on itself, mingling past, present, and future in a visionary weave of dream, memory, and reflections.

This volume, edited and with a superb introduction by W.H. Auden and Norman Holmes Pearson, presents the greatest of the Romantics in all the fullness and ardor of their vision, including William Blake, Robert Burns, Samuel Taylor Coleridge, William Wordsworth, Lord Byron, Percy Bysshe Shelley, John Keats, Ralph Waldo Emerson, Henry David Thoreau, and Edgar Allan Poe. What emerges is a panoramic view of a generation of artists struggling to remake the world in their own image—and miraculously succeeding.

Hydrogen sulphide (H2S) is a colourless gas which occurs naturally in some environments such as sulphur springs, swamps and salt marshes, and is often associated with the decomposition of organic material. In this book, the authors present research on the sources, detection and health hazards of hydrogen sulphide. Topics discussed include the methods of detecting hydrogen sulphide in the environment; technologies for hydrogen sulphide removal; and oral disease and hydrogen sulphide production by oral bacteria.
