“Huxley’s layer” and “membrane” of the root sheath of hair follicles.

Includes Huxley’s classification of mankind by means of the hair. The full text was originally published in the Fortnightly Review, I, 1865, 257-76. The full text was reprinted in Huxley's Critiques and addresses (1873).

This series of six lectures delivered to “working men” in November and December, 1862 includes Huxley’s first book-form exposition of Darwin’s theories, of which he was probably the greatest popular exponent. A prolific essayist as well as author of hundreds of scientific papers, Huxley was one of the most eloquent of all English writers on the natural sciences. 

Huxley showed that in the visible characters man differs less from the higher apes than do the latter from lower members of the same order of primates. He also provided the first thorough and detailed comparative description of the Neanderthal remains in English. The first issue of the first edition did not include a Table of Contents.

Huxley proposed a close relationship between birds and dinosaurs after the discovery in Germany of the primitive fossil bird Archaeopteryx. He made detailed comparisons of Archaeopteryx with various prehistoric reptiles and found that it was most similar to dinosaurs like Hypsilophodon and Compsognathus.

Huxley was among those who refuted Owen’s theory of the vertebral skull.

Presents virtually all of Huxley's scientific papers arranged in chronological order, as well as reports of his Royal Institution Friday Evening Discourses. The final supplemental volume contains the remainder of Huxley’s survey memoir on fossil fishes, along with three papers not collected elsewhere.

Huxley served as assistant surgeon and naturalist aboard the Rattlesnake (1845-50) which made cruises from Australia to Louisiade Archipelago, New Guinea and Cape York. His diary is illustrated with his own drawings.

"Those merely interested in Huxley and scholars engaged in research on him, on Darwinism, on Victorian culture, on the history of science, and on topics such as those noted will find that THE HUXLEY FILE, in which reside over 1000 items, justifies its title. The 1000 figure covers 680 pieces of published and unpublished text by THH; more than 150 pictures by and on him, with an uncounted number of pictures in text by and for him; and 120 commentaries on him. Cybernauts will find here

• the entirety of the nine-volume Collected Essays;
• 40 selections from the five-volume Scientific Memoirs;
• and also a large number of Huxley essays that were never collected, from The Westminster Review, Youth's Companion, etc.; among these, the most important hidden pieces are the three essays he wrote for a club, The Metaphysical Society, on whether a frog has a soul, whether immortality is reasonable, whether Jesus was actually resurrected;
• several pieces that exist only in draft form, such as his teenage journal "Thoughts and Doings," "Agnosticism–A Fragment" and "The Natural History of Christianity";
• letters published in The Times, Nature, etc.; most of the letters appear in Leonard Huxley, ed., The Life and Letters of Thomas Huxley and Julian Huxley, ed., Thomas Henry Huxley's Diary of the Voyage of H.M.S. Rattlesnake –which is the best provider of THH's diary items; some of the letters come from collections in libraries around the world.
• a cornucopia of illustrations ranging from his doodles and sketches of natives to cartoons and portraits of him, illustrations not attached to any text, and a number illustrating texts such as Man's Place in Nature and Oceanic Hydrozoa.
• 120 commentaries on him, some praising his work, others attacking it, such as Powheads, Porwiggles and Protoplasm."
