We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Gray, who ardently desired that these valuable materials should be used in continuation of the plan begun by the donor, it was arranged that I should undertake the work in connection with Mr. Thomas P. James, of Cambridge, who would make the microscopical analyses of such species as had not yet been satisfactorily examined, and prepare sketches from which descriptions could be drawn.
As large numbers of specimens and even whole collections were sent to us for determination, the work progressed slowly, but it was drawing toward completion when two years ago Mr. James was suddenly called away by death.

Leo Lesquereux was a Swiss paleobotanist. He served as a consultant for state geological surveys in several U. S. states.
Background
Leo Lesquereux, the son of V. Aimé and Marie Anne Lesquereux, was born on Novermber 18, 1806 in the village of Fleurier, in the canton of Neuchâtel, Switzerland. His ancestors were French Huguenots--victims of the Edict of Nantes. His father was a manufacturer of watchsprings; his mother, a woman of education who aspired to see her son a minister in the Lutheran church and to this end persisted in attempting to make him a classical scholar. In this effort she failed. The boy could not and would not confine himself to his books, but early developed an almost uncontrollable enthusiasm for outdoor life and natural history. In one of his early mountain-climbing expeditions, when he was about ten years old, he fell from a high crag and was so badly injured that for days his life was despaired of, though he ultimately recovered with only the partial loss of hearing in one ear as a permanent result.
Education
When he was thirteen, at his mother's earnest solicitation he went to the academy at Neuchâtel to study, but though he did well in arithmetic and French, in Latin and Greek he failed.
Career
Following graduation, Lesquereux accepted a position at Eisenach, Saxony, as professor of French, expecting to earn enough to pay his own expenses. Increasing deafness forced Lesquereux to give up teaching. For a while he eked out a somewhat scanty living for his wife and children by engraving watchcases, and in time formed a partnership with his father in the manufacture of watchsprings. During his prolonged incapacity from a serious illness, his wife learned a branch of the trade and supported the family until his recovery.
Cut off almost completely from social intercourse by his deafness, he turned his attention back once more to nature, particularly to the mosses and lower forms of plant life, quickly mastering his subject and constituting himself a recognized authority. About this time, the Swiss government, in view of the increasing scarcity of fuel, offered a prize for the best essay on the formation and preservation of the peat bogs, which had become the chief source of supply. Lesquereux won the prize with his Recherches sur les Tourbières du Jura (1844). Furthermore, the essay brought him in touch with Jean Louis Rodolphe Agassiz, Arnold Henry Guyot, his former classmate, and other scientific men of the day. The episode proved a turning point in his career.
The Swiss government next employed him to prepare a small textbook on peat for use in the schools, and created for his especial benefit the office of director of peat bogs. He was also--through the social influence of his wife, it is said--employed to report upon the peat bogs of Germany, Sweden, Denmark, and France. Unfortunately, while he was engaged in these congenial tasks the political revolutions of 1847-1848 came about, and all employees of the existing government were ousted. Agassiz had gone to America in 1846, and Lesquereux and his friend Guyot followed, landing in Boston in September 1848. Lesquereux was at this time in his forty-second year, "stone deaf, " and unable to speak English. Nevertheless he triumphed over his handicap by learning to read lip movements, and ultimately was able to carry on conversation with three persons at once, speaking English, French, and German in turn, although it was necessary in such case that he be told in advance the language each individual was to speak. Since his own speaking knowledge of English was gained after he reached America, his vocalization was bad, as with deaf mutes in general.
His first scientific work in the United States was the classification of the plant collection made during the Agassiz expedition of 1848 to Lake Superior. Later he moved to Columbus, Ohio, where he became associated with the eminent cryptogamic botanist, William Starling Sullivant, in his bryological work. He then turned to a systematic study of the coal plants and quickly became the recognized authority on matters relating to the entire Appalachian coal field, with the literature of which his name must be forever associated.
His most valued single contribution is his "Description of the Coal Flora of the Carboniferous Formation in Pennsylvania and Throughout the United States" (Second Geological Survey of Pennsylvania: Report of Progress, P. , 3 vols. in 2, 1880-84), but he is to be credited also with the determinations of the coal plants for the Kentucky survey of 1860, the Illinois survey of 1866 and 1870, the Indiana survey of 1876 and 1884, as well as the Tertiary plants of the Hilgard survey of Mississippi and the Cretaceous and Tertiary plants of the Hayden survey of the Dakotas.
Lesquereux's deafness cut him off from all attendance on society meetings and he was known intimately to few. He had a very modest opinion of his own merits. He died in Columbus, Ohio, in his eighty-third year.
Achievements
Despite the fact Lesquereux lacked formal training in botany, he became a celebrated and much published figure in the field of paleobotany. He conducted pioneer research and analysis on the origin, composition and development of peat. He also developed theories on the origin of coal formations and performed pioneer investigations of Paleozoic flora.
The plant genus Lesquerella from the family Brassicaceae and the testate amoeba genus Lesquereusia were named in his honor.

Membership
He was honored by membership in the leading scientific societies of Europe and was the first member to be elected to the National Academy of Sciences after its organization.
Personality
Quotes from others about the person
He "was a devout Christian believer. . He extended his creed to take in all scientific discoveries, but he did not count any of its essentials disturbed thereby. He seems never to have been reached by the currents of modern thought which have overflowed the old foundations for so many. "
"A homelier, a more beautiful face I never saw. The homeliness was in the flesh; the beauty was the varying expression of a perfectly lovely spirit. He was a little man with inexhaustible powers of life. His eyes were limpid; his smile heavenly; his gratitude for the smallest favors from men and his childlike confidence in the care of God, unbounded. Everybody trusted and loved him. " - Peter Lesley.
Connections
Lesquereux met Sophia von Wolffskeel von Reichenberg, the daughter of General von Wolffskeel, at Eisenach, Saxony and despite the discrepancy in their respective stations, between Lesquereux and this young woman a mutual attachment developed which was ultimately allowed to culminate in marriage.
