Two 18th Century Scientific Papers on The Human Life Expectancy

1754315Life expectancy is a statistical measure of how long a person or organism may live based on the year of thei birth yheir current age and other demographic factors including gender. At a given age life expectancy is the average number of years that is likely to be lived by a group of individuals of age xexposed to the same mortality conditions until they die.Mathematically life expectancy is the mean number of years of life remaining at a given age assuming constant mortality rates.Longevity and life expectancy are not synonyms. Life expectancy is defined statistically as the average number of years remaining for an individual or a group of people at a given age Longevity refers to the characteristics of the relatively long life span of some members of a population. Moreover because life expectancy is an average a particular person may well die many years before or many years after their "expected" survival. The term "maximum life span"has a quite different meaning and is more related to longevity. WikipediaThe methodology for determining life expectncy has evolved over the years. The accuracy of the projections has a pronounced effect on both the societal and economic interests of individuals and governments. The two papers here descibe some of the work done in the 18th century to evaluate and improve the estimates of life expectancy. The two papers are:A View of the Relation between the celebrated Dr. Halley's Tables and the Notions of Mr. De Buffon for establishing a Rule for the probable Duration of the Life of Man; by Mr. William Kerssboom of the Hague. Translated from the French by James Parsons M. D. and F.R.S. London: Philosophical Transaction 1754. The preparation of statistical tables to predict life expectancy was performed by competing analysts. In this paper Mr. Kerssboom compares several tables to determine why they differ from each other. The item is a First Edition extracted and disbound from The Philosophical Transactions of the Royal Society Vol. 48 For the Year 1753 pages 239-252. This volume of the Transactions was published in London in 1754.A Letter to the Rev. Dr. William Brakenridge Rector of St. Michael Bassishaw London and F.R.S. concerning the Term and Period of Human Life: In which the inequalities in constructing and the false Conclusions drawn from Dr. Halley's Breslau Table are fully proved; the supposed extraordinary Healthfulness of that Place is particularly examined and confuted; and its real State equated by divers Place in England; the imperfection of all the Tables formed upon 1000 Lives is shewn; and a Method proposed to obtain one much better: By T. W. A.M. London: Philosophical Transactions 1763. The ability to improve life expectancy tables as more data and more recent information is considered is demonstrated in this paper. The item is a First Edition extracted and disbound from the Philosophical Transactions of the Royal Society This volume Vol. 52 For the Years 1761 & 1762 pages 46-70. This volume was published in 1763.The illustrations accompanying this description show the first page of each paper. Royal Society's Philosophical Transactions paperback

179758364Kiøbenhavn Johan Rudolph Thiele 1797 1799. 4to. Uncut and unopened in original blue boards. Published in: "Nye Samling af det Kongelige Danske Videnskabernes Selskabs Skrifter." Vol. V. Wessel's paper: pp.469-518 and 3 folded engraved plates the last plate inserted at p. 463. The whole volume V offered in its original binding. Engraved titlevignette. XII670 pp. 15 engraved plates. 4 leaves with upper right corners gone not affecting Wessel's paper. First edition of this important first systematical treatment of the theory of complex numbers and at the same time the first work to add vectors in three-dimensional space."Wessel’s fame as a mathematician is based entirely on one paper written in Danish and published in the Mémoires of the Royal Danish Academy that established his priority in publication of the geometric representation of complex numbers. John Wallis had given a geometric representation of the complex roots of quadratic equations in 1685; Gauss had had the idea as early as 1799 but did not explicitly publish it until 1831. Robert Argand’s independent publication in 1806 must be credited as the source of this concept in modern mathematics because Wessel’s work remained essentially unknown until 1895 when its significance was pointed out by Christian Juel. The title of Wessel’s treatise calls it an "attempt" to give an analytic representation of both distance and direction that could be used to solve plane and spherical polygons. The connection of this goal with Wessel’s work as a surveyor and cartographer is obvious. The statement of the problem also suggests that Wessel should be credited with an early formulation of vector addition. In fact Michael J. Crowe in A History of Vector Analysis University of Notre Dame Press 1967 defines the first period in that history as that of a search for hypercomplex numbers to be used in space analysis and dates it from the time of Wessel whom he calls the first to add vectors in three-dimensional space."

WATSON, The Reverend JohnBiblio.com

The History and Antiquities of The Parish of Halifax in Yorkshire Illustrated with Copper-Plates.

17753730London: Printed for T.Lowndes 1775 1775. First edition. 4to. 265x210mm. pp. iv 764 10 index. Ten engraved plates frontispiece portrait of the author and a further nine. The verso of the second leaf of preliminaries is numbered vi. Some foxing in places but otherwise internally very good with the plates in excellent condition. Handsomely bound in slightly later red straight-grained morocco upper and lower covers decorated with two double fillet borders in gilt enclosing a continuous "drawer-handle" design in blind and framing a continuous swag and drop border in blind. Spine with five double raised bands decorated in gilt and blind and lettered in gilt to the second and fifth compartment. Edges of the boards decorated in gilt. Turn-ins decorated in gilt with a wavy dotted line and ears of wheat with a flower motif in the corners. All edges gilt. The binding is of a very high standard. It is unsigned but the tooling and overall design conforms to the work of the German emigré binders and we would tentatively attribute the binding to either Christian Kalthoeber or John Bohn and date it to the 1790s or the very early years of the 1800s. A previous owner has inscribed the verso of the front free endpaper "Bound by Edwards of Halifax ". This seems unlikely but it is possible given the subject matter of the book and the links between Edwards and the German emigré binders that this copy did pass through Edwards's hands. John Watson 1723-1783 was that perfect eighteenth-century combination of clergyman and antiquary. He was the curate of Halifax between 1750 and 1754 and retained links with the town throughout his life. Starting with Druidical remains and moving through Roman affairs Watson brings the reader up to the eighteenth century. He covers the history of Halifax and provides details of the main buildings in the town as well as exploring fascinating byways such as "Remarks on the Dialect of Halifax""Vocabulary of Uncommon Words used in Halifax" and "A Catalogue of Plants Growing in the Parish of Halifax".

Washington, George; Levi Sheftall; Hebrew Congregation of the City of SavannahBiblio.com

Gazette of the United States June 19 1790 FIRST PUBLISHED JEWISH SUPPORT FOR PRESIDENT GEORGE WASHINGTON

179052510New York: John Fenno no. 41 Broad-Street near the Exchange 1790. First edtion. Softcover. Fine. Two leaves folio 16.25 by 10 in. Edges slightly trimmed; a touch of mild foxing else a fine crisp copy. Housed in linen clamshell box with gilt paper label at spine and previous owner's dediction pasted to inside cover. The first known published appearance of Jewish support for the newly elected president of the United States George Washington. One week after Washinton's inauguration Levi Sheftall on behalf of the newly reorganized Savannah Hebrew Congregation wrote him an elegant and effusive letter of congratulation. This letter along with Washington's reply was published for the first time by the United States Gazette: "Sir We have long been anxious of congratulating you on your appointment. and of testifying our unbounded confidence in your integrity and unblemished virtue. Your unexampled liberality and extensive philanthropy have dispelled that cloud of bigotry and superstition which has long as a veil shaded religion -- unrivetted the fetters of enthusiasm -- enfranchised us with all the privileges and immunities of free citizens and initiated us into the grand mass of legislative mechanism. May the great Author of worlds grant you all happiness and a continuance of guardianship to that freedom which under the auspices of heaven your magnanimity and wisdom have given these States." Washington's reply is undated but addressed "To the Hebrew Congregation of the City of Savannah." After accepting their congratulations he extends this hope: "May the same wonder-working Deity who long since delivering the Hebrews from their Egyptian Oppressors planted them in the promised land -- whose providential agency has lately been conspicuous in established these United States as an independent nation -- still continue to water them with the dews of Heaven and to make the inhabitants of every denomination participate in the temporal and spiritual blessings of that people whose God is Jehovah. George Washington." Provenance: old entry of . Hopkins at top margin first leaf trimmed. Six weeks later References: Enc. Jud. first ed. 1972 vol. 16; Evans Amer. Bibl. vol. 8; From the Ends of the Earth Judaica Treasures of the Library of Congress. John Fenno, no. 41 Broad-Street, near the Exchange unknown
