JEFFRIES WYMAN. MEMORIAL MEETING BOSTON SOCIETY OF NATURAL HISTORY, OCTOBER 7, 1874. JEFFRIES WYMAN. Died 4th September, 1874. THE wisest man could ask no more of Fate Than to be simple, modest, manly, true, Safe from the Many, honored by the Few; Nothing to count in World, or Church, or State, But inwardly in secret to be great; To feel mysterious Nature ever new, To touch, if not to grasp, her endless clew, And learn by each discovery how to wait; To widen knowledge and escape the praise; Wisely to teach, because more wise to learn; To toil for Science, not to draw men’s gaze, But for her lore of self-denial stern; That such a man could spring from our decays Fans the soul’s nobler faith until it burn.

AFTER our usual summer vacation we meet together with more than accustomed emotion: for, mixed with the joy of greeting one another after separation, there is a consciousness of irreparable loss that weighs heavily upon our spirits, a recognition that there have gone away from us a force and a virtue which have so long been a help and an inspiration, that we cannot but feel a sense of loss such as no words of mine can adequately express. Sad indeed is it for us and for all, that such nobleness of nature, such wealth of acquired knowledge, such purity and simplicity of life, as were mani- -fested in Jerrries Wymay, should pass from the world; for rare, too rare, are to be found examples of such exalted char- acter and attainments. To our Society Prof. Wyman was a great benefactor; not in the sense of a donor especially, but in the higher sense of one imparting to it such honorable fame as enhanced greatly respect for it, both at home and abroad. To him also was the Society mainly indebted for the interest shown in our work by the late Dr. Walker, and which led directly to its large endowment with the means of success. 7) 8 But pleasant as it would be for me, as a personal friend, to dwell upon the transcendent virtues of one whom I have always regarded with the highest respect and most affection- ate esteem, I feel it would be unbecoming to further occupy your time in view of those present, who have come here with their tributes of love to the memory of our dear departed friend. I therefore close by inviting others to address you, first callmg upon Prof. Gray, who, from his great regard for Prof. Wyman, has kindly prepared a notice of his life and work to read on this occasion. \| ADDRESS OF PROF. ASA GRAY. WueEn we think of the associate and friend whose death this Society now deplores, and remember how modest and re- tiring he was, how averse to laudation and reticent of words, we feel it becoming to speak of him, now that he is gone, with much of the reserve which would be imposed upon us if he were living. Yet his own perfect truthfulness and nice sense of justice, and the benefit to be derived from the con- templation of such a character by way of example, may be our warrant for reasonable freedom in the expression of our judgements and our sentiments, taking care to avoid all exag- geration. Appropriate and sincere eulogies and expressions of loss, both official and personal, have, however, already been pro- nounced or published; and among them one from the gov- ernors of that institution to which, together with our own Society, most of Professor Wyman’s official life and services — were devoted, —which appears to me to delineate in the few- est words the truest outlines of his character. In it the President and Fellows of Harvard University “recall with affectionate respect and admiration the sagacity, patience and rectitude which characterized all his scientific work, his clearness, accuracy and conciseness as a writer and teacher, (9) 10. and the industry and zeal with which he labored upon the two admirable collections which remain as monuments of his rare knowledge, method and skill. They commend to the young men of the University this signal example of a char- acter modest, tranquil, dignified and independent, and of a life simple, contented and honored.” What more can be or need be said? It is left for me; in compliance with your invitation, Mr. President, to say some- thing of what he was to us, and has done for us, and to put upon record, for the use of those who come after us, some account of his uneventful life, some notice, however imper- fect, of his work and his writings. I could not do this with- out the help of friends who knew him well in early life, and of some of you who are much more conversant than I am with most of his researches. Such aid, promptly ren- dered, has been thankfully accepted and freely used. Our associate’s father, Dr. Rufus Wyman, — born in Wo- burn, graduated at Harvard College in 1799, and in the latter part of his life Physician to the McLean Asylum for the In- sane, — was a man of marked ability and ingenuity. Called to the charge of this earliest institution of the kind in New England at its beginning, he organized the plan of treatment and devised the excellent mechanical arrangements which have since been developed, and introduced into other estab- lishments of the kind. His mother was Ann Morill, daughter of James Morill, a Boston merchant. This name is contin- ued, and is familiar to us, in that of our associate’s elder brother. Jerrries Wyman, the third son, derived his baptismal name from the distinguished Dr. John Jeffries, of Boston, under whom his father studied medicine. He was born on 11 the 11th of August, 1814, at Chelmsford, a township of a few hundred inhabitants in Middlesex Co., Mass., not far from the present city of Lowell. As his father took up his residence at the McLean Asylum in 1818, when Jeffries was only four years old, he received the rudiments of his educa- tion at Charlestown, in a private school; but afterwards went to the Academy at Chelmsford, and, in 1826, to Phillips Ex- eter Academy, where, under the instruction of Dr. Abbot, he was prepared for college. He entered Harvard College in 1829, the year in which Josiah Quincy took the presi- dency, and was graduated in 1883, in a class of fifty-six, six of whom became professors in the University. He was not remarkable for general scholarship, but was fond of chemis- try, and his preference for anatomical studies was already developed. Some of his class-mates remember the interest which was excited among them by a skeleton which he made’ of a mammoth bull-frog from Fresh Pond, probably one which is still preserved in his museum of comparative an- atomy. His skill and taste in drawing, which he turned to such excellent account in his investigations and in the lecture room, as well as his habit of close observation of nat- ural objects met with in his strolls, were manifested even in boyhood. An attack of pneumonia during his senior year in college caused much anxiety, and perhaps laid the foundation of the pulmonary affection which burdened and finally shortened his life. To recover from the effects of the attack, and to guard against its return, he made in the winter of 1833-34, the first of those pilgrimages to the coast of the Southern States, which in later years were so often repeated. Return- ing with strength renewed in the course of the following 12 spring, he began the study of medicine under Dr. John C. Dalton, who had succeeded to his father’s practice at Chelms- ford, but who soon removed to the adjacent and thriving town of Lowell. Here, and with his father at the McLean Asylum, and at the Medical College in Boston, he passed two years of profitable study. At the commencement of the third year he was elected house-student in the Medical Department, at the Massachusetts General Hospital, — then under the charge of Doctors James Jackson, John Ware and Walter Channing —a responsible position, not only most advantageous for the study of disease, but well adapted to sharpen a young man’s power of observation. In 1837, after receiving the degree of Doctor of Medicine, he cast about among the larger country towns for a field in which to practice his profession. Fortunately for science he found no opening to his mind; so he took an office in Bos- ton, on Washington Street, and accepted the honorable, but far from lucrative post of Demonstrator of Anatomy under Dr. John C. Warren, the Hersey Professor. His means were very slender, and his life abstemious to the verge of priva- tion; for he was unwilling to burden his father, who, in- deed, had done all he could in providing for the education of two sons. It may be interesting to know that, to eke out his subsistence, he became at this time a member of the Boston Fire Department, under an appointment of Samuel A. Eliot, Mayor, dated Sept. 1, 1838. He was assigned to Engine No. 18. The rule was that the first-comer to the engine- house should bear the lantern, and be absolved from other work. Wyman lived near by, and his promptitude generally saved him from all severer labor than. that of enlightening his company. 18 The turning point in his life, ¢.e., an opportunity which he could seize of devoting it to science, came when Mr. John A. Lowell offered him the curatorship of the Lowell Institute, just brought into operation, and a course of lectures in it. He delivered his course of twelve lectures upon Compara- tive Anatomy and Physiology in the winter of 1840-41; and with the money earned by this first essay in instructing others, he went to Europe to seek further instruction for himself, He reached Paris in May, 1841, and gave his time at once to Human Anatomy at the School of Medicine, and Comparative Anatomy and Natural History at the Garden of Plants, attending the lectures of Flourens, Majendie, and Longet on Physiology, and of de Blainville, Isidore St. Hilaire, Valenciennes, Dumeril, and Milne-Edwards on Zool- ogy and Comparative Anutomy. In the summer, when the lectures were over, he made a pedestrian journey along the banks of the Loire, and another along the Rhine, returning through Belgium, and by steamer to London. There, while engaged in the study of the Hunterian collections at the . Royal College of Surgeons, he received information of the alarming illness of his father; he immediatély turned his face homeward, but on reaching Halifax he learned that his father was no more. He resumed his residence in Boston, and devoted himself mainly to scientific work, under circumstances of no small discouragement. But in 1843 the means of a modest profes- sional livelihood came to him in the offer of the chair of Anatomy and Physiology in the medical department of Hampden-Sidney College, established at Richmond, Vir- ginia. One advantage of this position was that it did not interrupt his residence in Boston except for the winter and 14 spring; and during these months the milder climate of Richmond was even then desirable. He discharged the duties of the chair most acceptably for five sessions, until, in 1847, he was appointed to succeed Dr. Warren as Hersey Professor of Anatomy in Harvard College, the Parkman professorship in the Medical School in Boston being filled by the present incumbent, Dr. Holmes. Thus commenced Prof. Wyman’s most useful and honorable connection as a teacher with the University, of which the President and Fellows speak in the terms I have already recited. He began ~ his work in Holden Chapel, the upper tloor being the lecture- room, the lower containing the dissecting room and the anat- omical museum of the College, with which he combined-his own collections and preparations, which from that time for- ward increased rapidly in number and value under his in- dustrious and skillful hands. At length Boylston Hall was built for the anatomical and the chemical departments, and the museum, lecture and working-rooms were established commodiously in their present quarters; and Prof. Wyman’s department assumed the rank and the importance which it deserved. Both human and comparative anatomy were taught to special pupils, some of whom have proved them- selves worthy of their honored master, while the annual courses of lectures and lessons on Anatomy, Physiology, and for a time the principles of Zoology, imparted highly valued instruction to undergraduates and others. In the formation and perfecting of his museum — the first of the kind in the country, arranged upon a plan both physi- ological and morphological—no pains and labors were spared, and long and arduous journeys and voyages were made to contribute to its riches. In the summer of 18h9,— ; ng) 15 having replenished his frugal means with the proceeds of a second course of lectures before the Lowell Institute (viz., upon Comparative Physiology, a good condensed short-hand report of which was published at the time),— he accompanied Capt. Atwood of Provincetown, in a small sloop, upon a fish- ing voyage high up the coast of Labrador; in the winter of 1852, going to Florida for his health, he began his fruitful series of explorations and collections in that interesting district. In 1854, accompanied by his wife, he travelled extensively in Europe, and visited all the museums within his reach. In the spring of 1856, with his pupils, Green and Bancroft, as companions and assistants, he sailed to Surinam, penetrated far into the interior in canoes, made important researches upon the ground, and enriched his museum with some of its most interesting collections. These came near being too dearly bought, as he and his companions took the fever of the country, from which he suffered severely, and recovered slowly. Again, in 1858-9, accepting the thought- ful and generous invitation of Capt. J. M. Forbes, he made a voyage to the La Plata, ascended the Uraguay and the Parana in a small iron steamer which Capt. Forbes brought upon the deck of his vessel; then, with his friend George Augustus Peabody as a companion, he crossed the pampas to Mendosa, and the Cordilleras to Santiago and Valparaiso, whence he came home by way of the Peruvian coast and the Isthmus. By such expeditions many of the choice materials of his museum and of his researches were gathered, at his own expense, to be carefully prepared and elaborated by his own unaided hands. A vast neighboring museum is a splendid example of what munificence, called forth by personal enthu- 16 siasm, may accomplish. In Dr. Wyman’s we have an exam- ple of what one man may do unaided, with feeble health and feebler means, by persistent and well-directed industry, without eclét, and almost without observation. While we duly honor those who of their abundance cast their gifts into the treasury of science, let us not—now that he can not be pained by our praise — forget to honor one who in silence and penury cast in more than they all. Of penury in a literal sense we may not speak; for al- though Prof. Wyman’s salary, derived from the Hersey en- dowment, was slender indeed, he adapted his wants to his means, foregoing neither his independence nor his scientific work; and I suppose no one ever heard him complain. In 1856 came unexpected and honorable aid from two old friends of his father who appreciated the son, and wished him to go on with his scientific work without distraction. One of them, the late Dr. William J. Walker, sent him ten thousand dollars outright; the other, the late Thomas Lee, who had helped in his early education, supplemented the endowment of the Hersey professorship with an equal sum, stipulating that the income thereof should be paid to Prof. Wyman during life, whether he held the chair or not. Sel- dom, if ever, has a moderate sum produced a _ greater benefit. Throughout the later years of Prof. Wyman’s life a new museum has claimed his interest and care, and is indebted to him for much of its value and promise. In 1866, when fail- ing strength demanded a respite from oral teaching, and required him to pass most of the season for it in a milder cli- mate, he was named by the late George Peabody one of the seven trustees of the Museum and Professorship of American Li Archeology and Ethnology, which this philanthropist pro- ceeded to found in Harvard University; and his associates called upon him to take charge of the establishment. For this he was peculiarly fitted by all his previous studies, and by his predilection for ethnological inquiries. These had already engaged his attention, and to this class of subjects he was thereafter mainly devoted,— with what sngacity, consummate skill, untiring diligence and success, his seven annual Reports — the last published just before he died,— his elaborate memoir on shell-heaps, now printing, and especially the Archeological Museum in Boylston Hall, abundantly testify. If this museum be a worthy memorial of the found- er’s liberality and foresight, it is no less a monument of Wy- man’s rare ability and devotion. Whenever the enduring building which is to receive it shall be erected, surely the name of its first curator and organizer should be inscribed, along with that of the founder, over its portal. Of Prof. Wyman’s domestic life, let it here suffice to record, that in Dec., 1850, he married Adeline Wheelwright, who died in June, 1855, leaving two daughters; that in Au- gust, 1861, he married Anna Williams Whitney, who died in February, 1864, shortly after the birth of an only and a sur- viving son. Of his later days, of the slow, yet all too rapid progress of fatal pulmonary disease, it is needless to protract the story. Winter after winter, as he exchanged our bleak climate for that of Florida, we could only hope that he might return. Spring after spring he came back to us invigorated, thanks to the bland air and the open life in boat and tent, which acted like a charm;—thanks, too, to the watchful care of his attached friend, Mr. Peabody, his constant companion in 2 18 Florida life. One winter was passed in Europe, partly in ref- erence to the Archeological Museum, partly in hope of bet- ter health; but no benefit was received. The past winter in Florida produced the usual amelioration, and the amount of work which Dr. Wyman undertook and accomplished last summer might have tasked a robust man. There were im- portant accessions to the archeological collections, upon which much labor, very trying to ordinary patience, had to be expended. And in the last interview I had with him, he told me that he had gone through his own museum of com- parative anatomy, which had somewhat suffered in conse- quence of the alterations in Boylston Hall, and had put the whole into perfect order. It was late in August when he left Cambridge for his usual visit to the White Mountain region, by which he avoided the autumnal catarrh; and there, at Bethlehem, New Hampshire, on the 4th of Septem- ber, a severe hemorrhage from the lungs suddenly closed his valuable life. Let us turn to his relations with this Society. He entered it in October, 1837, just thirty-seven years ago, and shortly after he had taken his degree of Doctor in Medicine. He was Recording Secretary from 1839 to 1841; Curator of Ichthyology and Herpetology from 1841 to 1847, of Herpe- tology from 1847 to 1855, of Comparative Anatomy from 1855 to 1874. While in these later years his duties may have been almost nominal, it should be remembered that in the earlier days a curator not only took charge of his portion of the Museum, but in a great degree created it. Then for fourteen years, from 1856 to 1870, he was the President of this Society, as assiduous in all its duties as he was wise in council; and he resigned the chair which he so long adorned 1g and dignified only when the increasing delicacy of his health, to which night-exposure was prejudicial, made it unsafe for him any longer to undertake its duties. The record shows that he has made here one hundred and five scientific commu- nications,! several of them very important papers, every one of some positive value; for you all know that Prof. Wyman never spoke or wrote except to a direct purpose, and be- cause there was something which it was worth while to communicate. He bore his part also in the American Acad- emy of Arts and Sciences, of which he was a Fellow from the year 1843, and for many years a Councillor. To it he made a good number of communications; among them one of the longest and ablest of his memoirs. Then he was from the first a member of the Faculty of the Museum of Comparative Zoology, where his services and his advice were highly valued. He was chosen President of the American Association for the Advancement of Science for the year 1857, but did not assume the duties of the office. Some notice — brief and cursory though it must be— of such portion of Dr. Wyman’s scientific work as is recorded in his published papers, should form a part of this account of his life. His earliest publication, so far as we know, was an article in the Boston Medical and Surgical Journal, in 1837, signed only with the initials of his name. It is upon “ The indis- _ tinetness of images formed from oblique rays of light,” and the cause of it. The handling of the subject is as character- istic as that of any later paper. In January, 1841, we find his first recorded communication to this Society, “On the tThe Royal Society’s Catalogue of Scientific Papers enumerates sixty-four by Prof. Wyman alone, and four in conjunction with others. 20 Cranium of a Seal.” The first to the American Academy is the account of his dissection of the electrical organs of a new species of Torpedo, in 1848, part of a paper by his friend Dr. Storer, published in “Silliman’s Journal.” In the course of that year, eleven communications were made to our Society, besides the Annual Address, which he delivered on the 17th of May. The most important of these was the memoir, by Dr. Savage and himself, on the Black Orang or Chimpanzee of Africa, Troglodytes niger, published in full in the Jour- nal of this Society, the anatomical part by Prof. Wyman. Two other papers of that early year, on the Anatomy of two Mollusea, Tebennophorus carolinensis and Glandina. trun- cata, published in the fourth volume of the Society’s Journal, each with a copper plate, are noteworthy, as showing that he possessed from the first that happy faculty of clear, terse, and closely relevant exposition, and that skill and neatness of illustration with his pencil, which characterize all his work, both of research and instruction. Another paper of that year, “ On the microscopic structure of tha teeth of the Lepidoste?, and their analogies with those of the Labyrinthodonts,” read to this Society in August, and published in Silliman’s Journal in October, 1848, was impor- tant and timely. In it he demonstrated that the labyrinthine structure of the teeth, considered at the time to be peculiar to certain sauroid reptiles, equally belonged to the gar-fishes, and consequently that many fossil teeth which had been re- ferred by the evidence of this character alone to a group of reptiles founded upon this peculiarity, might as well belong to ancient sauroid fishes. Although not of any importance now to remember, I may here mention his report to this Society on the Hydrarchos 21 Sillimani of Koch, a factitious Saurian of huge length, suc- cessfully exhibited in New York and elsewhere under high auspices, and I think also in Germany, but which Dr. Wy- man exposed at sight, showing that it was made up of an indefinite number of various cetaceous vertebrae, belonging to many individuals, which (as was afterward ascertained) were collected from several localities. But the memoir by which Prof. Wyman assured his posi- tion among the higher comparative anatomists was that, communicated to and published by this Society in the summer of 1847, in which the Gorilla was first named and introduced to the scientific world, and the distinctive struc- ture and affinities of the animal so thoroughly made out from the study of the skeleton, that there was, as the great English Anatomist remarked, “very little left to add, and nothing to correct.” In this memoir the “ Description of the habits of Troglodytes Gorilla,” is by Dr. Thomas §. Savage, to whom, along with Dr. Wilson, “belongs the credit of the discovery”; the Osteology of the same and the introductory history are by Dr. Wyman. Indeed, nearly all since made known of the Gorilla’s structure, and of the affinities soundly deduced therefrom, has come from our associate’s subsequent papers, founded on additional crania brought to him in 1849, by Dr. George A. Perkins of Salem; on a nearly entire male skeleton of unusual size, received in 1852, from the Rey. Wil- liam Walker, and now in Wyman’s museum; and on a large collection of skins and skeletons placed at his disposal in 1859, by Du Chaillu, along with a young Gorilla in spirits, which he dissected. It is in the account of this dissection that Prof. Wyman brings out the curious fact that the skull & 22 of the young Gorilla and Chimpanzee bears closer resem- blance to the adult than to the infantile human cranium. In Prof. Wyman’s library, bound up with a quayto copy of the Memoir by Dr. Savage and himself, is a terse but complete history of this subject, in his neat and clear hand- writing, and with copies of the letters of Dr. Savage, Prof: Owen, Mr. Walker, and M. du Chaillu. In the introductory part of the Memoir, Prof. Wyman states that “the specific name, Gorilla, has been adopted, a term used by Hanno in describing the wild men found on the coast of Africa, probably one of the species of the Orang.” The name, Troglodytes Gorilla, is no doubt to be cited as of Savage and Wyman, and it was happily chosen by Prof. Wyman, after consultation with his friend, the late Dr. A. A. Gould, for the reason just stated. But it is inter- esting to see, in the correspondence before me, how strenu- ously each of the joint authors deferred to the other the . honor of nomenclature. Dr. Savage from first to last insists, in repeated and emphatic terms, that the scientific name shall be given by Dr. Wyman as the scientific describer, and that he could not himself honestly appropriate it. Prof. W yman, in his Mss. account, after mentioning what his por- tion of the Memoir was, and that “the determination of the differential characters on which the establishment of the species rests was prepared by me,” briefly and characteris- tically adds: “In view of this last fact, Dr. Savage thought, as will be seen in letter, that the species should stand in my name; but this I declined.” : This Memoir was read before this Society on the 18th of August, 1847, and was published before the close of the year. But it had not, as it appears, come to Prof. Owen’s knowl- 23 edge when the latter presented to the London Zoological Society, on the 22d of February, 1848, a memoir founded on three skulls of the same species, just received from Africa through Capt. Wagstaff. When Prof. Owen received the earlier Memoir, he wrote to compliment Prof. Wyman upon it, substituted in a supplementary note the specific name im- posed by Savage and Wyman, and reprinted in an appendix the osteological characters set forth by the latter. “It does not appear, however (adds Dr. Wyman), either in the Pro- ceedings or the Transactions of the [Zoological] Society, at what time our Memoir was published, nor that we had antici- pated him in our description.” It is safe to assert that in this and the subsidiary papers of Dr. Wyman, may be found the substance of all that has since been brought forward, bearing upon the osteological resem- blances and differences between men and apes. After sum- ming up the evidence, he concludes : — “The organization of the anthropoid Quadrumana justifies the naturalist in placing them at the head of the brute creation, and placing them in a position in which they, of all the animal series, shall be nearest to man. Any anatomist, however, who will take the trouble to compare the skeletons of the Negro and Orang, cannot fail to be struck at sight with the wide gap which separates them. The difference be- tween the cranium, the pelvis, and the conformation of the upper extremities in the “Negro and Caucasian, sinks into comparative insignificance when compared with the vast difference which exists between the conformation of the same parts in the Negro and the Orang. Yet it cannot be denied, however wide the separation, that the Negro and Orang do afford the points where man and the brute, when the totality 24 of their organization is considered, most nearly approach each other.” Selecting now for further comment only some of the more noticeable contributions to science, we should not pass by his investigations of the anatomy of the Blind Fish of the Mam- moth Cave. The series began, in that prolific year, 1848, with a paper published in “Silliman’s Journal,” and closed with an article in the same Journal in 1854. Although Dr. Tellkamph had preceded him in ascertaining the existence of rudimentary eyes and the special development of the fifth pair of nerves, yet for the whole details of the subject, and the minute anatomy, we are indebted to Prof. Wyman. Many of the details, however, as well as the admirable drawings illustrating them, remained unpublished until 1872, when he placed them at Mr. Putnam’s disposal, and they were brought out in his elaborate article in the “American Naturalist.” Here the extraordinary development of tactile seuse, taking the place of vision, and perfectly adapting the animal to its subterranean life, is completely demonstrated. If Prof. Wyman’s first piece of anatomical work was the preparation of a skeleton of a bull-frog, in his undergraduate days, his most elaborate memoir is that on the anatomy of the nervous system of the same animal (tana pipiens), pub- lished-in the “ Smithsonian Contributions,” in 1852 (51 pages, royal 4to, with 2 plates). Anything like an analysis of thi§ capital investigation and exposition would much overpass our limits. For, although the special task he assigns to himself is the description of the nervous system of a single Batrachian, chiefly of its peripheral portion, and of the changes undergone during metamorphosis, he is led on to the consideration of several 25 abstruse or controverted questions ;— such, for instance, as the attempts that have been made to homologize the nervous system of Articulates with that of Vertebrates, upon which he has some acute criticism; — the theories that have been propounded respecting the functions of the cere- bellum and its relation to locomotion, which he tests in a characteristic way by a direct appeal to facts ;— the supposi- tion of Cuvier that the special enlargements of the spinal cord are in proportion to the force of the respective limbs supplied therefrom; which he controverts decisively by similar appeal, an extract from which I beg leave to append in a note.’ So, in describing the structure of the optic nerves in the frog, and the development of the eye and optic lobes, he pro- ceeds to remark, that — “The instances of Protews and Amblyopsis naturally sug- gest the questions, whether one and the same part may not combine functions wholly different in different animals, and 1
