TO THE PRESIDENT OF THE UNIVERSITY: SIR, — No new courses in Zoology were announced for 1916-17; but the designation of the course on Genetics and Eugenics was changed from Zoölogy 2 to Zoölogy 8. As much the larger number of students taking courses in Zoology do their work in the first half-year, the intensive military training and the various war service activities affected only a relatively small proportion of the students in the Department. The numbers of those in each of the second half-year courses who took the Zoological examinations prepared for the Reserve Officers' Training Corps, and likewise of those credited with the courses on a "short year' 99 on account of war service, are indicated in separate columns of Table I, which, as usual, shows the number of students from each class, or other division of the University, enrolled in each of the Harvard courses. Table II gives like information about the number of students from Radcliffe College. Special. 1 5 1 NOTE. 38+13 17+6 55 79 88 67 22 6 15 4 391 1922 * Zoology 8 was designated as Zoology 2 in the year 1915–16. Numbers in italics indicate students who attended the lectures, but were not enrolled in the course. The enrolments in Zoology 1 and Zoology 3 were larger than in any previous year, and about thirty-five applicants were excluded from Zoology 1 for want of adequate laboratory accommodations. The assistants in the several courses were: Zoology 1, Harvard: chief assistants, Messrs. S. Hecht and D. E. Minnich; subassistants, Messrs. J. P. Baumberger, S. W. Chase, A. B. Dawson, H. Jordan and P. H. Pope; Radcliffe: chief assistant, Mr. S. W. Chase; sub-assistant, Mr. A. B. Dawson. Zoölogy 3, Harvard: chief assistant, Mr. J. M. D. Olmsted; sub-assistants, Messrs. S. W. Chase and S. Hecht; Radcliffe: assistant, Mr. A. B. Dawson. Zoology 4, Harvard: assistant, Mr. J. M. D. Olmsted; Radcliffe: assistant, Mr. A. B. Dawson. Zoology 5, assistant in both Harvard and Radcliffe: Mr. A. C. Walton. Zoology 8: assistant, Mr. L. C. Dunn. The courses designated as Zoology 7a, 7b, 7c, and 10 were given at the Bussey Institution, the others in Cambridge. Eight of the students in Zoology 8 took laboratory work, the others were instead assigned reading with weekly conferences. Of the students in Zoology 146, four in Harvard and one in Radcliffe took the laboratory work, the others presented theses. In the University Extension Course in Elementary Zoology by Professor Parker there were twenty-four students. Mr. H. G. Coar was the assistant. Work in research, though in several cases interrupted by war demands, was counted as the equivalent of courses as follows: in courses; Zoology 20c, under Professor Parker, nine and a half courses; Zoology 20d, under Professor Castle, one course; Zoology 20e and 20g, under Assistant Professor Rand, seven and a half courses; Zoology 20f, under Professor Wheeler and Assistant Professor Brues, six courses; in Radcliffe, Zoology 20a, under Professor Mark, one course; Zoology 20c, under Professor Parker, two and a half courses; Zoology 20g, under Assistant Professor Rand, a half-course. Courses 20d and 20f were carried on at the Bussey Institution. The degree of Ph.D. was conferred in February on Alfred Clarence Redfield, whose thesis was on "The Physiology of the Melanophores of the Horned Toad," and in June on Selig Hecht, whose thesis was entitled "The Physiology of Ascidia atra Lesueur," and on Dwight Elmer Minnich, whose thesis was on "The Photic Reactions of the Honey Bee, Apis mellifera L.: A Quantitative Study in Circus Movements." Owing to the demands of the War, only one Harvard student in addition to the Resident Naturalist was at work at the Bermuda Biological Station during the summer. Aid from the Humboldt Fund to the amount of $150 was granted during the year. The Harvard Table at the Marine Biological Laboratory, Woods Hole, was occupied by a research student in physiology, and the Radcliffe table was shared by a Radcliffe Senior, pursuing physiology, and a Radcliffe Junior, who took the course in embryology. At the twenty-seven meetings held by the Zoological Club the average attendance was about 18. Thirty-three original papers and eleven reviews were presented. There have been issued during the year 47 publications by officers and students of the Department, including those which were published as Contributions from the Zoological Laboratory and as Contributions from the Bermuda Biological Station for Research, but not including those in Applied Zoölogy. The titles are printed in the current Report of the Director of the Museum of Comparative Zoology, and some of them have also been printed in the University Gazette. EDWARD L. MARK, Director. MINERALOGY AND PETROGRAPHY TO THE PRESIDENT OF THE UNIVERSITY: SIR, The removal of some of the laboratories of Mineralogy to Pierce Hall has been completed, affording greatly improved facilities there and diminishing fire risk in the Museum. In January, 1917, the Hancock collection of minerals was purchased for the Museum from the estate of the late Elwood P. Hancock of Burlington, N. J., by the trustees of the estate of Albert F. Holden, '88, this representing the first instalment of Mr. Holden's endowment. Mr. Hancock, who died in his eighty-second year, was a landscape painter who also carved in wood, and for sixty years an ardent collector of minerals. To this pursuit he brought his artistic eye and skilled manipulation with fine tools as well as an extraordinary instinct for fine and interesting specimens. For many years he made collection trips to American mineral localities and worked out the choice specimens he acquired with incredible skill so as to show their beauty. The collection has 1600 specimens, of generally first quality, and usually matrix specimens with good crystals; its great value as additional to our own collections lies in the superb crystals from such famous American localities as Franklin Furnace, Amelia Court House, Tilly Foster, etc. During the year 1917 the Department of Mineralogy and Petrography received a gift of novel character which it is hoped will prove in the future of much value to the work of instruction in the Department and to the Mineralogical Museum. The sum of three thousand dollars was placed at the disposal of the Chairman of the Department by an anonymous donor with which was secured a ninety-nine-year lease of the mineral rights on a tract of land embracing some sixty acres in the town of Greenwood, Maine. A large ledge of granite pegmatite containing gem tourmaline and other interesting minerals had been developed on this land by Mr. George L. Noyes of Norway, Me., who transferred to the Department all the minerals which he had taken from the ledge, a collection of several hundred specimens, including several handsome Museum groups and good representation of some twenty mineral species. A fund of seven hundred dollars was further subscribed by Mr. Edward Mallinckrodt of St. Louis and Mr. A. C. Burrage of Boston for the purpose of working the ledge. It proved to be impossible to undertake the work during the past summer, but it is hoped to do so in the future, and it appears practicable not only to obtain new and valuable material for the Museum but also to study the structure and geologic history of this type of deposit in a manner which has never been possible elsewhere notwithstanding the abundant operation of gem quarries in other parts of New England. It is also hoped that a summer camp may eventually be established on the property where advanced students may take advantage of the opportunity for mineralogical studies not only at the immediate locality but as well in the numerous mineral occurrences within easy reach from this point as a center. A number of fine specimens have been received from various friends, especially from members of our Visiting Committee. In common with other departments of the University our officers have assisted in the instruction of the Harvard R. O. T. C., especially in topography. JOHN E. WOLFF, Curator. |
