HISTORICAL AND GENEALOGICAL REGISTER, FOR JULY, 'is??; By WILLIAM GAMMELL. O 162 MEMOIR. The deatli of this beloved and honored educator took place at his residence in Providence, R. I., on the eighth day of January, 1877, at the age of nearly seventy-eight years. He had been a member ef the New England His- toric, Genealogical Society since 1870, and was an active promoter of its objects. His high character, his honorable services as a teacher of science, and the eminent positions which he so worthily filled, unite in demanding a somewhat extended notice of his life and career in the pages of the Register. Alexis Caswell was a twin son of Samuel and Polly (Seaver) Caswell, and was born in Taunton, January 29, 1799. His twin brother Alvaris is still living in a vigorous old age in Norton. Before the birth of the twins there were born of the same parents one sister and three brothers, and one sister and two brothers afterwards. The younger sis- ter died in childhood. All the others lived to mature age. The eldest brother and the twin brother alone remain. The family has resided in Taunton from the first settlement of the town. At the date of its incorporation in 1639, the name of Thomas Caswell .appeared in the list of its house- 6 MEMOBIALOF holders and proprietors. Like the other original settlers he probably came from Taunton, in Somersetshire, England, and his Avill was admitted to probate in 1697, which was undoubtedly the year in which he died. From him in the sixth generation the subject of this notice was descended in a direct line. His grandfather, Ebenezer Caswell, who was born in Taunton, June 30, 1731, married Zibiah White, the great-grand-daughter of Peregrine White, who was born on board the Mayflower while anchored off Cape Cod, Nov. 20, 1620, and who died in Marshfield, July 22, 1704. His ancestors, from the date of their settlement in New England, had been owners and tillers of the soil, and, as was to be expected, his own early years, were devoted to agricultural labors on his father's estate. As manhood approached, he soon formed the purpose of obtaining a liberal education in order that he might prepare for some profes- sion. For this the Academy in his native town afforded the facilities which he. required. He accordingly, in 1815, be- came a member of this institution, of which the Rev. Sim- eon Doggett was at that time the preceptor. In September, 1818, at the age of nineteen years, he entered the freshman class in Brown University. Among his classmates were William Allen Crocker and Samuel Leonard Crocker, of Taunton, who had been his fellow students at the Academy, and an unusual number of others whose names have since been well known to the public. Among them may be men- tioned the Rev. Benjamin Clarke Cutler, Isaac Davis, Thomas Kinnicutt, Solomon Lincoln and Jacob Hersey Loud. His college life was distinguished for industry, and on his graduation in 1822 he bore the highest honors of his class, and according to the usage, spoke the valedictory addresses at commencement. During this period, also, he experienced ALEXIS CASWELL. 7 that moral change which made him a genuine and earnest christian man, and which, more than any other event, shaped his entire subsequent life. In July, 1820, he became a mem- ber of the First Baptist Church in Providence, and of that church he continued to be a member so long as he lived, every year binding him to it by closer ties and more tender associations, till his character and influence came at length to be regarded as precious treasures by all his brethren. Immediately on completing his college residence he accepted an appointment as tutor in the institution now known as Columbian University, at Washington, D. C, an institution which was then in its infancy, having been founded only in the year preceding; and he entered upon his duties there in September, 1822. In the performance of these duties he spent the five following years. The presi- dent of the College was the Rev. Dr. Staughton, a Baptist clergyman from England, who had considerable reputation for eloquence and learning, and with him Mr. Caswell also studied theology and practised the composition of sermons. The years spent at Washington were years of earnest work, varied with occasional attendance on the debates in one or the other house of congress, and with vacation excursions into Virginia, to the homes of students who resided at the college. In one of these excursions he visited ex-President Madison, and also ex-President Jefferson, and shared the hospitalities of each of these venerable men. Public life at Washington fifty years ago was invested with an interest for an educated young man which it no longer possesses, and the debates in congress seemed then to have an importance wliich they have long since lost. The time to him passed quickly away, and he always looked back upon it as a profile able period of his life. It undoubtedly created within him 8 MEMORIAL OF the tastes and inclinations which led him to the profession that he adopted, and which controlled his subsequent career. In the summer of 1827 the finances of the institution with which he was connected became embarrassed, and Mr Caswell with others of its instructors withdrew from it. He immediately returned to New England in search of employment, intending probably to seek a settlement as a minister of the gospel. He was soon invited to visit Hali- fax, N. S., where a few families of culture and refinement, who had been connected with the Anglican church, were desirous of forming a Baptist church and maintaining wor- ship as a separate congregation. In this journey he was the companion of the Rev. Irah Chase, D.D., at that time a professor in the Theological Institution at Newton, Mass. The church was formed, and the services of Mr. Caswell proving acceptable, he was ordained as its minister on the 7th of October, 1827. Here he spent nearly a year, and here, as it proved, he began and ended his settled ministry of the gospel. In August, 1828, he received an intimation that his services would be required in Providence by the church of which he was a member, as assistant to the venera- ble pastor, the Rev. Dr. Gano, who had become disabled by ill health. He soon returned to Providence, arriving there just before the death of Dr. Gano. While temporarily sup- plying the pulpit of this church, the professorship of Mathe- matics and Natural Philosophy in Brown University became vacant by the resignation of the Rev. Alva Woods, D.D., and he was chosen to fill the vacant chair. The position was an honorable one, and was also in harmony with his intellectual tastes and his previous occupations. He immediately accepted the appointment, and the work on which he entered became the work of the remainder of his life. ALEXIS CASWELL. 9 He was now once more a resident at the place of his edu- cation, a professor in the college in which he had spent the years of his student life, and with whose history and sur- roundings he was familiar. He was in the thirtieth year of his age, and in the full vigor of his manly strength. The college, eighteen months before, had passed from the presi- dency of Dr. Messer to that of Dr. Wayland, who had brought to its administration great energy of character and rare enthusiasm for the work of education. He had estab- lished a higher standard of instruction and a more exact system of discipline than had before prevailed. The change was so marked that it for a time encountered no little opposition. Professor Caswell, however, gave to it his hearty support, and entered into the new arrangement with energy and zeal. His influence began immediately to be felt among those who were under his tuition and care. The college was at that time but imperfectly provided either with books or with the means of scientific illustration and experiment. Its departments of instruction were not fully organized, and new sciences had been added to its course of study before professors were appointed to teach them. He was always ready to assume any additional duties that were required to meet the emergency. In this manner, in addition to his own regular work, he at different times taught classes in chemistry, in natural history, in ethics and in constitutional law. The funds of the institution, too, were exceedingly inadequate to its wants, and he was soon enlisted in an enterprise for increasing them. In labors like these for the general prosperity of the University did he begin his career as a professor, and they were but a specimen of those that marked it to its close. He was always self- sacrificing and public spirited, and wholly beyond his 10 MEMORIAL OF special department of instruction, lie rendered services of great importance to the institution with which he was connected. No life is more uniform and quiet than that of a college instructor. He is constantly occupied with scientific or literary studies, and with the teaching of classes. He can seldom mingle in the excitements which lie without the sphere in which he lives. He has cares and annoyances, and, it may be, ambitions, all his own, but they are not like those of other men. He has few public relations compared with those of other professional men. The rule is now undoubtedly far less inflexible than it was fifty years ago, but it has not essentially changed. Such a life is still com- paratively without events, and is distinguished mainly by the uniformity of its current. Such was it in the case of Professor Caswell. Day succeeded day, and year followed year, and still he was at the same work of study and of teaching. In 1850 the style of his professorship was changed from that of mathematics and natural philosophy to that of mathematics and astronom}^, a portion of his former work having been assigned to another. Of the science of astronomy he was an assiduous votary, and though he had not the advantages of an observatory, yet with such instruments as he had at command, he was constantly scanning the starry heavens and watching the occultations and transits which they revealed. He also kept himself carefully informed of the progress made in the science, and was in frequent correspondence with several of its eminent promoters. In 1855 the presidency of the University became vacant by the resignation of Dr. Wayland, who had filled the office since 1827. Professor Caswell was now the senior member of the faculty, and had rendered important ser- ALEXIS CASWELL. 11 vices to the UniYersity and to the cause of education, and it was naturally expected that he would be chosen to fill the vacancy. In this expectation he probably shared. Another, however, was preferred, on the ground that certain advan- tages would be secured by calling to the position one who had not hitherto been connected with the University. The occurrence made no change in his devotion to its interests. He continued to discharge the duties of his professorship without any apparent disappointment, and he gave to the new president the same cordial support which he had given to his predecessor. In 1860 he went abroad with Mrs. Caswell, and spent a year in travelling in Europe. During his absence he made the acquaintance of many eminent men of science, visited several of the great observatories, and attended the meet- ings of some of the leading scientific associations, both of Great Britian and the Continent. Returning in 1861, he resumed his duties and continued them till the autumn of 1863, when he resigned the professorship, after a service of thirty-five years. This service had been almost un23rece- dented in duration, and had been in many ways productive of signal advantages to the University. He was greatly respected and beloved by the scholars whom he taught. His public spirit had aided in promoting and securing many improvements, and he had the happiness of seeing the insti- tution making constant progress during the period of his connection with it — a progress to which his own labors and character had largely contributed. The cessation of regular academic occupations was of course a very great change in his habits of life. He, however, soon supplied their place, and filled up his unaccustomed leisure with scientific studies and philanthropic labors of various kinds in the 12 MEMORIAL OF community. He had a share in nearly every important enter- prise of this character that was undertaken, and he always yielded readily to the claims which the higher interests of society are constantly making on the time and energies of generous-minded citizens. He also became actively con- cerned in the management of certain financial corj)orations with which his interests were connected, and was made the president of the National Exchange Bank, and also of the American Screw Company, both of which were established in Providence. In September, 1867, the presidency of the University again became vacant by the resignation of the Rev. Dr. Sears, who had held it for twelve years. No small difficulty was experienced in obtaining a successor. An election was made, but it was declined, and the vacancy was not finally filled till the following January, when Dr. Caswell was chosen president. He Avas now sixty-nine years of age ; but he was in good health, and the duties to which he was called were, for the most part, such as he had been familiar with during his whole professional life. His occupancy of the position, of course, could not be regarded as other than temporary, either by himself or by those who elected him. It was deemed a judicious arrangement for meeting a some- what critical emergency in the affairs of the University, and he entered upon it with a cheerful confidence in his resources. With the office, while he held it, no duties of instruction were connected, in order that his energies might not be overtasked. The experiment was not without its risks, and the success in which it resulted afforded a very gratifying proof not only of the facility with which he could resume, at a late period of life, the academic labors which he had laid aside, but also of the intellectual vigor and the ALEXIS CASWELL. 13 genial Spirit which years seemed scarcely to have abated. His administration was entirely creditable to him, and his venerable character and long services contributed to its success. He withdrew from the office in September, 1872, having held it four years and a half, and he left the Univer- sity in all respects in a better condition than that in which he found it. Its students had become more numerous ; its funds had been increased; a new professorship had been established, and an important enlargement had been made of its museum of natural history. The years of his presi- dency, added to those during which he was a professor, make the whole period of his services in Brown University thirty-nine and a half years — a period not equalled, save in a single instance, by any other officer of instruction in its entire history. In the year following his resignation he was elected a trustee, and two years later he was elected a fellow in its corporation, thus continuing his connection with its management to the end of his life. As appears from the foregoing sketch, the entire active life of Dr. Caswell, with the exception of the brief year of his ministry at Halifax, was spent in the study and teaching of science, a work eminently favorable to the culture of the intellect and the elevation of the character. Such a work is, of itself, a contribution to the interests of science, for it extends its influence over many minds, and trains a multi- tude of students to be its votaries, its promoters or its dis- coverers. Such may now be found among his pupils, whose first aspirations were awakened and encouraged by him. Neither of the sciences, however, which he was engaged in teaching was such as to invite him, in any special degree, to original researches of his own. If astronomy is an excep- tion, it is only with the aid of an observatory and the special 14 M E M O E I A L O F facilities which it affords, that such researches can be attempted with advantage. But he was an expert mathe- matician and a thorough expounder of the laws of mechanical philosophy ; and with the progress of astronomical science he kept up a minute acquaintance, and was exceedingly fond of its study. For this purpose he maintained a fre- quent correspondence with those who were prosecuting it in circumstances more propitious than his own. He was one of the early members of the American Association for the Promotion of Science, and often served on its important committees. He was President of this Association for a year, and delivered the customary official address at its annual meeting, held in Springfield, in 1859. He was also one of those who are named in the Act of Congress, approved March 3, 1863, which created the National Academy of Science. At the preliminary meeting of its members for organization, held in New York the following April, he was made temporary secretary and also chairman of the committee on the plan of organization. When the Academy was organized and its members were arranged in sections, he was assigned to the section on astronomy, geography and geodesy. He was also, at the same meeting, appointed on a committee created at the request of the Navy Department, to report upon certain questions relating to the method of preparing and publishing charts of winds and currents, and also of the sailing directions connected therewith. It was one of the objects of the Academy to give advice on questions of science when called upon to do so by the government of the United States. At the annual meeting held in January 1866, in accordance with an appointment previously made, he read a carefully pre- pared paper on the life and scientific services of the late ALEXIS CASWELL. 16 Professor Benjamin Silliman, a member of the Academy, who had died just before the preceding annual meeting. Very early in his career as a man of science, he began to keep a daily meteorological record, which he continued to the end of his life. These records were published every month in the Providence Journal, and compilations of them have appeared in the volumes of the Smithsonian Institution. He also, at the invitation of Professor Henry, the head of that Institution, delivered a course of lectures on astronomy in its hall, at Washington, in the winter of 1858. The published writings of Dr. Caswell are comparatively few, and these for the most part are scattered among the transactions of learned societies, or the scientific and literary periodicals to which they were contributed. He had no fondness for the preparation of text-books, though often urged to the undertaking in connection with some one of the sciences which he was engaged in teaching. Even the few papers which he published were prepared at the solici- tation of the editors of the journals in which they appeared. He of course wrote a large number of annual reports, for the University and for the various institutions, literary, charitable and religious, with which he was connected, and in which his services were very frequently put in requisition for this purpose. He published now and then a discourse prepared for some public occasion. He also wrote fre- quently for the newspaper press, and often discussed subjects in a series of articles which were thus presented to the public. Apart from publications of this kind, the fol- lowing list contains all those with Avhich his name is known to be connected : Oration before the Phi Beta Kappa Society of Brown University in 1835. 16 MEMOKIALOF Whewell's Bridgewater Treatise, an Article in the Chris- tian Review for June, 1836.

The Future of Africa, from the Baptist Quarterly, July 1875. From his character and services as a man of science we turn to contemplate him in his relations to the community and to the interests of philanthropy and religion. His services here have already been incidentally alluded to as signally honorable and useful. His natural benevolence was very strong, and this quality of his character was ALEXIS CASWELL. 17 heightened by his sense of religious duty to his fellowmen. He was interested in every enterprise that was designed to relieve the miseries or to elevate the character of the human race, or to bring them under the influence of true religion. In him the poor always found a friend and a benefactor. A teacher himself, he was a life-long promotor of popular, as well as of scientific, education. He was also enlisted in the efforts of those who were engaged in the abolition of war, and of those who were laboring for the benefit of the freed- men of the South, and scarcely less in the improvement of their brethren in Africa. Even before his days of leisure began, he generously shared in the labors and expenditures of the public charities of Providence, and he soon began to give to these charities much of his time and attention. His continued connection with the Boards of the University has been mentioned, and it did not fail to bring with it some special cares and duties. At the organization of the Rhode Island Hospital in 1863, he was appointed one of its trustees, and after faithfully discharging this trust for twelve years, he was, in 1875, chosen president of the Hos- pital, an office which he continued to hold to the end of his life. He performed for this important institution a great amount of work, and afforded it much valuable aid by his counsels. Such was the estimation in which his services and character were held by those who were associated with him in the management of the hospital, that a few of his friends have, since his death, endowed a free bed within its walls in honor of his memory, which is to bear forever the name of " The President Caswell Free Bed." He was also, for several years immediately preceding his death, one of the inspectors of the State Prison, where he often conducted religious services on Sundays ; and he was much interested 18 MEMORIAL OF in the questions relating to prison discipline, and in the well being of those whom this discipline concerns. The religious opinions and sentiments of Dr. Caswell were decided and earnest, and they blended gracefully with every attribute of his character and entered into all the pursuits and scenes of his life. Though they were asso- ciated with positive articles of faith and united him with a particular branch of the Christian Church, they were very far from being exclusive or narrow. They were derived rather from the Bible than from any school of theology. As was well said of him by his recent pastor at his funeral, " His secret life was nourished out of profound convictions, out of a perpetual communion with an invisible world and a living God. His were not occasional excursions into spiritual regions, but a constant walk with God. There was in him a beautiful, we may say, an uncommon combination of the spiritualities of a sincere religion with the activities, the interests, the joys of life." His religious faith and his scientific conclusions were never seriously at variance with each other. He believed that Nature and Revelation were alike, in their respective modes, manifestations of the charac- ter and will of God, and he did not doubt that the teachings of the Bible, when rightly interpreted, would prove to be in full harmony with the teachings of all true science. His faith in the Copernican system was scarcely greater than his faith in the ultimate prevalence of Christianity throughout the world. He believed it to be designed to become the religion of mankind. He was, therefore, an earnest advo- cate and a liberal promoter of Christian missions, as one of the most important agencies for reclaiming and improving the human race. He watched their operations and rejoiced in their successes in every quarter of the globe. He regarded A L EX'I'S CAS WE L L . 19 them as tlie grandest enterprise in CTiristian history, and as the. continuation of the work begun by the Apostles at the comrriand of our Lord himself; and he delighted to con- template their connection with the ultimate destiny of man as an immortal being. The life of such a man could hardly fail to be happy. His temperament was cheerful and his liealth almost uni- formly good. Though in early life he was wholly dependent on his own exertions, industry and prudence had secured for him a liberal competence. His relations to others were kindly and benignant, and his domestic life was singularly fortunate. He bore the trials and sorrows, from which no human lot is free, with serene composure and with devout submission to the Divine Will. He lived to nearly four- score years, and yet without seeming to be old. With his faculties scarcely dulled by age, with his children and grand- children around him, he received the consideration and respect which are always so readily accorded to those who have served well the generation to which they belong. He was called to suffer from no wasting disease, from no linger- ing decay of strength. He was withdrawn by only a few days of illness from the activities and duties in which he greatly delighted, and he died as he had lived, in calm submission to his Heavenly Father's will, and with an unfaltering faith in the life and immortality which are brought to light in the gospel. Dr. Caswell was twice married : first, on May 7, 1830, to Esther Lois, daughter of Edward K. Thompson, of Provi- dence, who died June 25, 1850 ; second, on January 31, 1855, to Elizabeth Brown, daughter of Thomas Edmands, of Newton, Mass., who survives her husband. Of the first marriage six children were born, of ^whom three died in 20 MEMORIAL. infancy, and three survive their father, viz. : Sarah Swoope, wife of James B. Angell, LL.D., president of the Univer- sity of Michigan ; Dr. Edward Thompson Caswell, physician of Providence, and Thomas Thompson Caswell, Paymaster in the Navy of the United States. MEMORIAL: PREPARED FOR THE AMERICAN ACADEMY OF ARTS AND SCIENCES, AND PUBLISHED IN ITS PROCEEDINGS. By Prof. JOSEPH LOVERING, OF HARVARD UNIVERSITY. :»,T / ]'■(•) :> ■;: i : ;: V ( / i *.;;.< i .- «; 5: 'i y > d /.iiior.iii: '. ./. : On the Stli of January, 1877, Rhode Island lost, by death, an accomplished man of science, and one of her best citizens. Alexis Caswell was born in Taunton, Mass., on the 29th of January, 1799. His ancestors, on the father's side, were prosperous farmers, and were among the earliest settlers of Taunton. Thomas Caswell, of the fifth genera- tion preceding, came, according to tradition, from Somerset- shire, England. His will was admitted to probate in 1697; only fifty-eight years after the incorporation of Taunton. The grand-father of Alexis married Zibiah White, who was the great-grand-daughter of Peregrine White, the first born of the Pilgrims in America on Board the May-flower, Novem- ber, 1620. Alexis Caswell, after spending his early years upon the farm, was prepared for college at the Bristol Academy in Taunton. Little is known of his character and attainments at this time ; but, if the child is father of the man, he must have been amiable, docile, and full of high ambition. At the age of nineteen he entered Brown Univer- sity, over which Dr. Messer then presided. His course in college was eminently successful; and, at his graduation, in 1822, he received the first honors. From 1822 to 1827, he was connected with Columbian College, Washington, D. C, as tutor or professor of lan- guages ; at the same time studying theology under Dr. Stoughton, the President. In the autumn of 1827, he went with Dr. Irah Chase (professor in the Newton Theological Seminary fi-om 1825 to 1843), to Halifax, for the purpose of 24 MEMORIAL OF establishing the Granville Street Baptist Church in that place. His plans were changed, in consequence of an invi- tation which he received from the people to remain among them. He was ordained on the 7th of October, and settled over them as their pastor. Having preached to them accept- ably for a year, he received an invitation from the First Baptist Church in Providence in the summer of 1828 to assist the Rev. S. Gano, the pastor of that church. He had been in Providence only a few weeks, when he was appointed Professor of Mathematics and Natural Philosophy in Brown University. "With the exception of the time when he visited Europe, in 1860-1861, he discharged the laborious duties of this office for thirty-five years, to the complete satisfaction of the government and the pupils of the institution. Engaging in its instruction soon after Dr. Wayland's accession to the presidency, he was his strong support throughout an able and vigorous administration. In many respects, one was the fitting complement of the other, and respect and confidence were felt equally on each side. In 1840, while Dr. Wayland was absent in Europe, Professor Caswell discharged the duties of President ; and, during the last three years of President Wayland's official term. Professor Caswell, under the title of Regent, relieved him from all the anxieties of discipline, bringing to this delicate duty qualities df mind and heart which secured good order without alienating the affection of the students. When Dr. Caswell resigned his professorship in 1863, he was sixty-four years of age ; and had fairly earned the leisure and the retirement which are the reward and luxury of old age. But he was still young in the best sense of the word ; young in his feelings, in his habits of industry, in his intellectual faculties, in the good constitution which he had ALEXIS CASWELL. 26 inherited from his father, (who died in 1851 at the advanced age of ninety-one), and young in his passion to serve his day and generation to the end. Accordingly, he engaged in active affairs with a vigor and success which younger men might well have envied. Refreshed by five years, not of repose, but of a change of his intellectual diet, he again obeyed the voice of his Alma Mater, which called him, in 1868, to the Presidency of Brown University ; Dr. Sears, his predecessor, having been summoned to an urgent and diffi- cult service by the strong voice of patriotism and humanity. Although Dr. Caswell had been moving for a few years outside of the University domain, his heart was always there. He knew, better probably than any one else, the wants, the resources, and aims of the institution ; and, notwithstanding that he stood on the brink of threescore years and ten, he brought to his high position the vigor, the freshness, and the hope of youth. Among the various needs of the University which he pressed upon the attentiori of the corporation, in his annual reports, was the establishment of an astronomical observatory, sufficient for the purposes of instruction if not of research. Soon after leaving the office of president, in 1872, Dr. Caswell was elected into the Board of Trustees, and, in 1875, he was chosen a fellow of the corporation. In 1841, he received the degree of D.D., and, in 1865, that of LL.D. ; both from his own University. For nearly fifty years, he had been associated with it, either as student, teacher, president, trustee, or fellow : and in each and all of these relations, he had reflected back all the honors which he had received as a favorite son. Earnest, devoted, and generous himself, he had the power and the disposition to enlist others, of larger means, in the same cause. None of its distinguished children 4 26 MEMORIALOF has exceeded him, perhaps none has equalled him, in length of service and fidelity to its sacred trusts. The special function and the high delight of Dr. Caswell were those of an educator. When he began his profession of teacher, he shared the fate of his contemporaries in older and richer universities in a new countiy. He was responsible for all the instruction given in mathematics and natural philosophy ; in fact, he alone represented the scientific side of the institution to which he was attached. Afterwards, a professor of chemistry, and at a much later period professors of natural philosophy or mathematics, were associated with him; so that, in 1850, his own duties were restricted to astronomy, from 1851 to 1855 to mathematics and astronomy, and after 1855 to natural philosophy and astronomy. It could not be exjDected of any man who was required to scatter his energies over a variety of subjects, which in a well appointed university would tax the best efforts of half a dozen professors, that he should have much leisure or dispo- sition for original investigation in one direction. It was enough, and more than enough, for the most laborious and ambitious teacher that he should maintain a high standaid of scholarship in the wide field which circumstances forced him to cultivate. Much has been written during the last few years in regard to the endowment of scientific research. But this is a luxury of which no one dreamed in Dr. Caswell's day ; and its strongest advocates at the present time are not in agreement as to the best way of accomplishing the desirable result. Mr. Huxley may be correct in his opinion that a moderate amount of teaching will not check but stimulate the zeal of the original explorer. But no one will think that a mind, wearied by excessive teaching, distracted by a multiplicity of topics, and prevented from rising in his ALEXIS CASWELL. 27 instruction to the Alpine heights of science by the dulness or indiffeience of the average student who despairs even of reaching the table-land, is a congenial soil for advancing human knowledge. Under such circumstances, one of two things must happen — either the work of teaching will be neglected, or that of original research will be left to men more favorably placed. It must not be inferred from these remarks that Dr. Cas- well was contented to remain stationary. At no time, since his scientific life began, has it been an easy task even to keep in sight the few who are steadily advancing the outposts of science ; and, of late, it is quite impossible without con- centration. Dr. Caswell's predilection was for meteorology and astronomy. During the period of twenty-eight and a half years (from December, 1831, to May, 1860), he made, with few interruptions, a regular series of meteorological observations, at the same spot on College Hill, in Provi- dence. These observations, precise as regards temperature and pressure, and including also much information on winds, clouds, moisture, rain, storms, the aurora, &c., have been published in detail in Vol. XII. of the "• Smithsonian Con- tributions to Knowledge," and fill 179 quarto pages. Dr. Caswell continued his observations in meteorology with unabated zeal, to the end of 1876 ; covering, in all, the long period of forty-five years. It is to be hoped that the latter portion of the series will be published soon under the same favorable auspices as the former. If it be true, as the Astronomer Royal of Greenwich believes, that meteorology is in too crude a state to claim the rank of a physical science, such labors as those of Dr. Caswell are among the means of making it one. And, certainly, at this moment, the interests and hopes involved in the subject are beyond 28 M E M O R I A L O F anything which Dr. Caswell could liave imagined when he began his work. Dr. Holyoke's meteorological observations in Salem, (published in the Memoirs of this Academy,) began in January, 1786, and continued to March, 1829. Mr. Hall's observations in Boston, (also published in the Memoirs of the Academy), embrace a period of forty-nine years, viz.- from 1821 to 1865. The observations of Dr. Hale, also made, in Boston, between 1817 and 1848, are preserved in the archives of the Academy for future publication. These various series, arranged in sequence, may answer the question, — What changes has a century brought to the climate of New England ? So far as the observations are contemporaneous, they will indicate the amount of influence to be ascribed to local causes or instrumental defects. In 1858, Dr. Caswell delivered four lectures on astronomy at the Smithsonian Institution in Washington. They were of the liighest order of popular instruction, and, on that account, were thought by Professor Henry worthy of being permanently preserved in his printed report for that year. Whatever may have been, or may still be, the conflict between science and theology, there is no conflict between science and religion ; least of all in Dr. Caswell's mind. He says in his introductory remarks : " The mechanism of the heavens, in proportion as we comprehend more and more of its vastness and seeming complexity, bears witness to the enduring order and harmony of the universe, and points with unerring certainty to the superintending agency of an intelligent and infinite Creator." And again : " We spon- taneously pay the tribute of our homage to all great achieve- ments. But in no case is homage more just or more enduring than that which all cultivated minds pay to him who stands as the minister and interpreter of Nature, and makes known ALEXIS CASWELL. 29 to US her laws and her mysteries. Many such adorn the annals of astronomy." Dr. Caswell joined the American Association for the Advancement of Science at its second meeting, which Avas held at Cambridge in 1850. Although he made no formal contribution to its proceedings, he was a frequent attendant upon the annual meetings, took part in the discussions, and always gave dignity to its deliberations by his character and his words. In 1855, the Association had its ninth meeting in Providence ; and the hospitable reception then given to it, and the hearty appreciation felt for its labors, were largel)^ due to his influence. The members expressed their gratitude for this service by electing him as the vice-president for the next meeting, in Montreal. But the death of the President elect, Professor J. W. Bailey of West Point, called Dr. Caswell to the chair. At this large representation of the science of the Continent (the only meeting which has taken place outside of the limits of the United States), he sustained the credit of his country on a foreign soil, by his dignified presence and his manly eloquence, . to the great satisfaction of all his associates. At such a time and in such a position. Dr. Caswell appeared to great advantage. By his dignity, his address, and his courtesy, he was eminently qualified to be a presiding officer ; and he was gifted with a fluency, a felicity, and a weight of speech which rose to the requirements of the occasion. At the next meeting of the Association in Baltimore, the president and vice-president elect were absent, and every hand was uplifted in favor of placing Dr. Caswell again in the chair. Having been called to preside over two of the most brilliant gatherings of this scientific body, he was expected to discharge the last duty of a retiring president by giving the address at Springfield. 30 MEMOEIAL OF After showing that science had an intellectual value far transcending its practical use, he discussed the objects, the opportunities, and the hopes of science in America ; drawing his illustrations chiefly from astronomy, partly because it was his favorite study, and partly because it had the start of all others in material resources. In this excellent address, admirable in thought, spirit, and style. Dr. Caswell reiterates his conviction that genuine science is not unfriendly to religion. " We participate in no such fear. We wish explicitly to exonerate this Association from all suspicion of undermining, or in any manner weakening, the foundations of that faith which an apostle says was once delivered to the saints. We cannot admit the opinion that any progress in science will ever operate to the disparage- ment of that devout homage which we all owe to Him in whose hand our breath is, and whose are all our ways. Science, on the contrary, lends its sanction and adds the weight of its authority to the sublime teachings of revela- tion." In this connection, two other scientific publications of Dr. Caswell may be mentioned : I. On Zinc as a covering for buildings ; " American Journal of Science," 1837. II. Review of Nichol's Architecture of the Heavens ; " Christian Review," 1841. Dr. Caswell was elected an Associate Fellow of this Academy in 1850. He was one of the original members of the National Academy of Sciences. He wrote for that body a Memoir of that worthy pioneer in American Science, Benjamin Silliman, which has been printed in one of its volumes of Proceedings. In this retrospect of the life and labors of Dr. Caswell, he has been seen almost exclusively in his professional relations as the student and teacher of science. And here his mind ALEXIS CASWELL. 31 look more delight in ranging over a wide field than in dissecting some single flower or tracing the path of a soli- tary molecule, although that may be a microcosm in itself. He could not have become one of Berkeley's minute philosophers. He was no specialist, though he was never superficial. If he was not himself an original discoverer, he understood and admired the discoveries of others, and led others to do likewise. At one time he taught Butler's Analogy at the university, and with as fresh an enthusiasm as if that alone had been the chosen work of his life. And wherever there was a gap in the means of instruction, he was the person thought to be fitted to fill it. His whole nature revolted at the suggestion of becoming a book-worm or a secluded student. He was emphatically a man of the world, though not of it. He was interested in trade, manu- factures, and finance. He was a good citizen, and took an active part in promoting the industrial, intellectual and moral welfare of his city, his State, and the whole country. His sympathies were deep and generous. Always welcomed in the circles of the refined and educated, he will be no less missed in the homes of the poor and the unfortunate. His heart and mind and strength were liberally expended in the administration of the public charities of the city and State. Dr. Caswell was an earnest speaker, and a clear, warm, and vigorous writer. To his publications, already mentioned, may be added : 1.
