For the hydrogen coma of comet P/Halley, both a Lyman-alpha image and extensive Lyman-alpha scan data obtained by the Pioneer Venus Orbiter Ultraviolet spectrometer as well as H-alpha ground-based spectral observations obtained by the University of Wisconsin Space Physics Group were successfully interpreted and analyzed with our Monte Carlo particle trajectory model. The excellent fit of the model and the Halley data and the water production rate determined near perihelion (9 Feb. 1986) from 13 Dec. 1985 to 13 Jan. 1986 and from 1 Feb. to 7 Mar. 1986 are discussed. Studies for the circumplanetary distribution of atomic hydrogen in the Saturn and Neptune systems were undertaken for escape of H atoms from Titan and Triton, respectively. The discovery of a new mechanism which can dramatically change the normal cylindrically symmetric distribution of hydrogen about the planet is discussed. The implications for the Titan-Saturn and Triton-Neptune are summarized.

The word <i>technocracy</i> refers to a system of government by technical experts such as scientists, technologists, and engineers. William Henry Smyth is often thought to have invented the term in 1919, although it had in fact been used earlier. (Summary following Wikipedia)

2Sailor's Word-book, A - C

By William Henry Smyth

An encyclopaedia (a digest, the author calls it) of nautical terms and other words relevant to navigation, the character of seamen, this book is full of surprising meanings for words in a nautical context. The original was published as one book, here divided into volumes. - Summary by Czandra

3Sailor's Word-book, D - G

By William Henry Smyth

An encyclopaedia (a digest, the author calls it) of nautical terms and other words relevant to navigation, the character of seafarers, fish and mathematics, weaponry and sailcraft. This book is full of surprising meanings for words in a marine context. It is practically useful to mariners; and for the etymologist it's a box of chocolates, some delightfully intuitively confected. The original was published as one book, here divided into volumes. This is the second volume. - Summary by Czandra

4Sailor's Word-book, H - M

By William Henry Smyth

A digest of sea terms and phrases, including flora, fauna, fish, fowl and fable of the sea, weaponry aboard ship, parts of a ship, qualities of a seaman, insurance, trading, and so on. The author says of Shakespeare, whom he quotes often, "[he] knew everything." The same can be said of Admiral Smyth. - Summary by Czandra

5Sailor's Word-book, N - R

By William Henry Smyth

A digest of sea terms and phrases, compiled with precision and humour for the instruction of sailors new and old, as well as their land-lubbing admirers. - Summary by Czandra

6Sailor's Word-book, S - Z

By William Henry Smyth

A compendium of fascinating words describing the world from far reaches of the visible universe to the ocean depths, along with creatures large and small, from the store of knowledge of a lettered navigator and seaman. The root of words is satisfyingly revealed in this and preceding volumes, A - R, as well as many words now fallen into the abyss of history. Summary by Czandra

[Professor's Smyth's] object is to teach students, and readers generally, how to read history for themselves; to show them the path, and furnish them the best lights for pursuing it; to enable them to form a just estimate of the principal authors, and to bring forward in bold relief those prominent parts of history to which their attention should chiefly be directed. His plan is unfolded with clearness and precision in his Introductory Lecture. It is broad and comprehensive, and such as could not have been carried out, in the finished manner it has been, without a critical examination of a large number of authors, and close and patient meditation upon the contents of their works. There is nothing superficial or ill digested; nothing taken at second hand; the lecturer's mind is brought to bear, with its own original vigor, upon all the subjects that come under his notice; his opinions are frankly and fearlessly expressed, and sustained by a force of reasoning which rarely fails to produce conviction, never to inspire respect and confidence.<br><br>He adopts a method at once perspicuous and well suited to the end he has in view. He selects certain periods of history, and groups together the great events in each, investigating their relation to each other in the order of cause and effect, and their results on the civil and political condition of states and communities; preserving, as he advances, an easy and natural transition from one period to another. This method affords occasion for philosophical reflections, in which the author is profound and sagacious, without any of the vague generalization and speculative theories which too much abound in works assuming the title of philosophical history. Professor Smyth's philosophy is of that rational kind which builds itself on established principles and truths, and in which he has so much respect for the good sense of his readers, that he is willing to address himself to their understanding. - Summary by American Preface
