To THE PRESIDENT AND FELLOWS or HARVARD COLLEGE: — During the past academic year the regular courses in Zoology, Geology, Geography, and Meteorology were given in the Natural History Laboratories of the Zodlogical Section (Museum of Com- parative Zoology) of the University Museum. It was hoped that the new southwest corner piece, the Geological Section, would be completed, so that the departments of Geology, Geography, and Meteorology would take possession, at the beginning of this academic year, of the laboratories and lecture rooms provided for them, and vacate the rooms now occupied, which are much needed by the Department of Zodlogy. As the building bas not been completed, the routine work of instruction will begin as before. Ten courses in Zoology were given by Professors Mark, Jackson, Parker, Drs. Castle and Rand, assisted by Messrs. Breed, Davis, Johnson, Ordway, and five Sub-Assistants. These courses were attended by two hundred and thirty-one students. Six courses in Zodlogy were given to forty-two students of Radcliffe College. HKighteen courses under the Geological Department, were given by Professors Shaler, Davis, Jackson, Ward, J. B. Woodworth, Drs. Jaggar, Daly, and Mr. Woodman, assisted by Messrs. Boyn- ton, Stone, Wilder, and five Sub-Assistants. The courses were attended by five hundred and forty-eight. Six courses were given to thirty-six students of Radcliffe College. The Summer School of Geology, held in the Museum, was attended by thirty-three students in two courses, given by Mr. H. T. Burr, assisted by Mr. C. H. Morrill. In recognition of his long service in successful administration of the instruction in Zodlogy under the Faculty of Arts and Sciences, Professor E. L. Mark has been appointed by the Cor- poration of the University Director of the Zodlogical Laboratory. 4 ANNUAL REPORT OF THE The principal addition to the exhibition collections has been a series of Japanese siliceous sponges for the Pacific room. A - number of birds have been added to the faunal and systematic series, and a fine specimen of the Snow Leopard of Thibet has been placed in the Europo-Siberian room. An additional case has also been constructed in this room. It is hoped that when the next report is issued the exhibit of paleozoic invertebrates will be open to the public, as considerable progress has been made in preparing the material for this exhibit. The Museum Assistants report the storage collections to be in excellent condition. In some depart- ments the accessions have been of unusual value. Details of these accessions will be found in the special reports. The installation of the large Bangs collection of mammals is now complete, and the old Museum collections have been incorpo- rated with it in a separate room. Mr. Bangs has given much of his time to this work. A large and valuable series of South American mammals has been received from the Messrs. Bangs. The expenses of installing the Bangs collection were partly met by an appropriation of five hundred dollars from the Corporation of the University, applied toward the construction of storage cases. Most important of the additions to the Department of Ornithol- ogy are the collections from the Hawaiian and Liu Kiu Islands. The latter collection contained a number of new forms, and has been reported on by Mr. Bangs in the “ Bulletin” of the Museum. There have been many gifts to the collection of recent inverte- brates, among which are the Emerton collection of spiders, the series of American ants from Professor W. M. Wheeler. From Mr. ¥. Du Cane Godman, through the British Museum, there has been received a set of duplicates of the land and fresh-water Mollusca of the Biologia Centrali-Americana. A representative collection of the rich siliceous sponge fauna of Japan, has been received from Mr. Agassiz. This exceptionally fine material has been mounted, and forms part of the exhibit of the Pacific room. Mr. Agassiz has also given to the Museum a large collection of alcoholic Jap- anese Marine radiates. From the U. 8S. National Museum has been received a duplicate series of the “* Albatross” (1891) ophi- urans reported on by Liitken and Mortensen in the ‘ Memoirs” of the Museum. The ‘‘ Blake”? Bathynomus material has been returned by Professor Bouvier, whose report will appear in the ‘“‘Memoirs.”” The Museum leeches have been sent to Professor - Percy Moore of Philadelphia for study. MUSEUM OF COMPARATIVE ZOOLOGY. 5) Dr. Eastman has again gone West in the interests of the Museum. His expedition of last year resulted in important additions to our palewozoic fishes and he reports having secured valuable new material for his department. The most important addition to the collections of the Museum is Mr. Agassiz’s gift of the Davis and McConathy collections of paleozoic corals. The Davis collection comprises more than eight thousand lots, the majority of which are the types of Major Davis’s work on the ‘“ Kentucky Fossil Corals.” Major Davis spent two months at the Museum in installing these collections. From Dr. J. M. Flint has been received a “‘ Class Microscope ”’ devised by him, and equipped with a rotary stage carrying about three hundred mounts of recent Foraminifera. The instrument is designed for exhibition purposes, and will be installed as soon as practicable. Mr. Henshaw reports that the accessions to the library are greater than those recorded in recent years. A complete change has been made in the arrangement of the stacks, the large north- west room being devoted exclusively to serials arranged alphabeti- cally under the geographical divisions adopted throughout the Museum. The two rooms of the Whitney Library have been assigned, one to geological and geographical serials and the other to the publications of geological surveys and to maps. Upwards of two hundred volumes and pamphlets treating of Ethnology have been transferred to the Peabody Museum, and nearly as many botanical works to the Gray Herbarium and the special libraries of the departments of Botany. Many duplicates have been trans- ferred to the general library of the University. By a vote of the Council of the University Library upwards of five hundred geologi- cal volumes and pamphlets were transferred from Gore Hall to the library of the Museum. It is earnestly hoped that the officers of the central library will continue this policy and in time transfer to the museum stacks such books in other departments of natural history as are not on our shelves. Such a segregation would make the Museum library the most complete of its kind and one of the strongest departments of the University. It would facilitate the work of students, and add much to the utility of the books and efficiency of the Museum, since books on systematic natural history are of little use apart from the collections of which they treat. From Walter Hunnewell, Esq., the Museum has received the 6 ANNUAL REPORT OF THE sum of five thousand dollars, given in memory of his son, Willard Peele Hunnewell, of the Class of 1904. By a vote of the Museum Faculty the income of this fund will be employed for the purchase . of books on Entomology. Hight numbers of the ‘ Bulletin” were issued during the year, comprising 383 pages and 74 plates. No numbers of the ‘* Memoirs” were published. The issues of the “ Bulletin”’ include Dr. Stejneger’s descriptions of lizards, No. XX VIII., “Albatross ” expedition of 1891, and Mr. Andrew’s report on his work for Mr. Agassiz on the geology of the Fiji Islands (Vol. XX XVIII., Geol. Ser., Vol. V.); two numbers of the ‘* Bulletin” were Contributions from the Zodlogical Laboratory under Professor Mark. By a vote of the Faculty of the Museum an annual appropriation from the funds of the Museum was made toward publishing in the “ Bul- letin ” original work of the officers and students in the department of Geology. Three such papers were published, in the fifth volume of the Geological Series of the “ Bulletin,” after a lapse of some years the department of Geology again taking part in the publications of the Museum. Mr. Frank Springer’s Memoir on Uintacrinus is nearly ready for distribution, and several reports of Mr. Agassiz’s ‘“ Blake,’ “ Albatross,” and “* Tropical Pacific’ Expeditions are in the hands of the printer. Volumes of XXXVII., XXXVIIL, and XXXIX. of the “ Bulletin” and XXV., XXVI., and XXVII. of the ‘‘ Memoirs” are in course of publication. Other publications dealing wholly or in part with collections of the Museum are: Jules Bonnier’s Epicaride (Tray. Sta. Zodl. Wimereux), Gamble and Ashworth’s Arenicolide (Quar. Jour. Micr. Sci.) and G. M. Allen’s Louisiana Deer (Amer. Naturalist). The Faculty of the Museum has granted me leave of absence for the winter to accompany Mr. Agassiz on his proposed expedition to the Maldive Islands. The islands of the Indian Ocean are the only groups of atolls remaining which Mf. Agassiz has not examined in his explorations for the study of coral formations. He has chartered a steamer from the British India Company which is to meet him at Colombo, Ceylon. It is expected that the work will occupy about two months. W. McM. WOODWORTH, Keeper of the Museum. MUSEUM OF COMPARATIVE ZOOLOGY. vi REPORT ON THE ZOOLOGICAL LABORATORY. By Proressor E. L. Mark.

Rand was appointed Instructor for the year 1900-01, and in addition to supervising the laboratory work in Courses 4 and 5 has had entire charge of Course 3. Dr. Castle has been made a member of the Faculty of Arts and Sciences; he will have charge of Courses 10 and 11, in addition to Course 2. Pro- fessor Parker gave for the first time a new half course (Zoology 13) on comparative histology, besides the courses which he gave in the preceding year. The names of the assistants in the various courses appear in connection with the statements about each course. The number of lectures in Zodlogy 1 was slightly increased, lectures having been given regularly every other Saturday, instead 8 ANNUAL REPORT OF THE of occasionally on that day, in addition to the Tuesday and Thurs- day lectures. The laboratory work was revised, and a new outline printed. By change in the laboratory hours the student is now required to do the laboratory work of each week on three consecu- tive hours, or, at least, without other interruption than that necessitated by attendance on the lectures of the course. This regulation has made the supervision of the laboratory work more methodical and efficient than when students were allowed to sepa- rate the hours of attendance, and it is not known to have obliged any student to give up the course. Professor Parker had as Chief Assistant, Mr. R. S. Breed, and as Sub-Assistants, Messrs. H. S. Davis, J. M. Johnson, and T. Ordway. The course was taken as an ‘‘extra” by four students not enumerated in the table. The laboratory work in Zodlogy 2 embraces the dissection and study of some ten or twelve types of animals, and varies some- what from year to year, according to the selection of forms made for work in Zodlogy 1. The course was given substantially as in former years. Dr. Castle had as Chief Assistant, Mr. H. Crawley. Mr. W. P. Hager was Sub-Assistant during about three-fourths of the course, and Mr, G. M. Allen during one-fourth. Owing to the fact that none of the assistants had had previous experience in assisting in this course, the instructor was compelled to devote more time than he ordinarily does to personal supervision of the laboratory work. The work in Zoology 4 was carried on as in former years. The laboratory was in charge of Dr. Rand, who also gave five lectures on the anatomy of Glossiphonia,—the animal used in studying various matters of technique. The remaining lectures of this course and those in Zodlogy 5 were given by Professor Mark. In the latter course Dr. Rand had charge of the laboratory work. The courses in Experimental Morphology were resumed, Dr. Castle, who is to give both these courses, having begun with Zodlogy 10, Ontogenesis. In the lectures were discussed the physi- cal and chemical peculiarities of living substance, and the effect upon it and its activities of various agents, such as chemical agents, heat, light, gravity, etc. The special topic of sex in animals and plants was also discussed at some length. Among the special topics for experimental work assigned to students were: acclimati- zation to high temperatures ; the effects of increased and diminished atmospheric pressure; the effect of close breeding in the case of MUSEUM OF COMPARATIVE ZOOLOGY. 9 some invertebrates; and certain questions connected with the determination of sex. The half course, Zodlogy 18, on comparative histology, with special reference to the nervous tissues, was given for the first time. The study of epithelium as a primitive tissue was followed by that of the derived tissues, nerve and muscle. There were two lectures a week, and the students each made and studied twenty preparations involving the use of modern methods in muscle and nerve histology. Professor Parker gave the course, without the — aid of an assistant. In Zodlogy 16, carried on as usual by Professor Parker, labora- tory work, opportunity for which was extended to a few students in the previous year, was made obligatory for all. It consisted in the investigation of special topics, one assigned to each student. Of the results from the eight topics assigned, three will probably be offered for publication. The lectures were attended by three graduate students not enrolled. There were ten students engaged in research (Zoology, 20 a) under the supervision of the Director of the Laboratory. Three of these completed their work and, as candidates for the Doctor’s degree, presented theses which were accepted. The theses of two others were nearly completed, and will be presented for acceptance early in the coming year. Mr. G. M. Allen began studies on the degenerate eyes of some common mammals; Mr. R. S. Breed continued with excellent results his problem in insect metamorphosis; Mr. H. Crawley wrote a paper on the absorption of fat by a common newt, which secured one of the Boylston Prizes offered by the Harvard Medi- cal School, and continued his studies on gregarines; Mr. C. A. Crowell made interesting discoveries on the growth of the ovum in reptiles; Mr. H. S. Davis worked on spermatogenesis, and Mr. J. M. Johnson on the nervous system of one of the Entomostraca ; Mr. A. W. Peters, in connection with his studies on the metabo- lism of Infusoria, devised some valuable apparatus and methods for rearing and handling minute organisms, a description of which has been published as No. 124 of the Contributions. The work of Mr. P. E. Sargent on Reissner’s Fibre has been continued, and a second preliminary paper, No. 122 of the Contributions, published ; that of Mr. W. A. Willard was nearly completed, and promises to be a valuable contribution to the knowledge of cranial nerves. 2 10 ANNUAL REPORT OF THE Mr. C. W. Woodworth has completed an extensive work on * The Wing Veins of Insects.” He returns next year to the chair of | Entomology in the University of California. Mr. Willard has assumed for next year the duties of the professor of biology in Grinnell (Iowa) College, who goes abroad for a year’s study. In June, 1901, the degree of Doctor of Philosophy was conferred upon the three following candidates in Zodlogy: Mr. Maurice Alpheus Bigelow, whose thesis was entitled ‘‘The Early Develop- ment of Lepas, a Study of Cell Lineage and Germ Layers;” Mr. Robert William Hall, thesis, ‘The Development of the Meso- nephros and the Miillerian Ducts in Amphibia;” and Mr. Reuben Myron Strong, thesis, ‘* The Development of Color in the Defini- tive Feather.” Dr. Bigelow holds the position of Instructor in Biology in the Teachers’ College, Columbia University, and Dr. Hall that of Assistant in Biology in Yale University. Dr. Strong takes a position in the Chicago University Academy, Morgan Park, Ill. Dr. Charles W. Prentiss has been appointed, upon the recom- mendation of the Division of Biology, to a Parker Fellowship for the year 1901-02, and has already sailed for Hurope, where he will pursue zoological investigations. The income of the Virginia Barret Gibbs Scholarship for 1900- 01 was divided between two students, Mr. Frederic W. Car- penter and Mr. Julius M. Johnson, both registered in the Graduate School. Thirteen persons, instructors and advanced students, have availed themselves of the opportunity for study afforded by the Laboratory of the U. S. Fish Commission at Wood’s Hole. Of these, nine have received aid from the income of the Humboldt Fund. The meetings of the Zodlogical Club were held as usual through- out the year from 4.30 to 6 o’clock, but on Friday afternoons instead of Thursday, as in the preceding year. Since the last report was made, Contributions Nos. 113-125 have been published. Appended is a list of — Contributions from the Zodlogical Laboratory for the Academie Year 1900-01. 113.

THE instruction given in this Department during the academic year 1900-01 was essentially the same as during the preceding year, with the exception of the usual changes involved in the bracketing and unbracketing of certain courses given in alternate years, and the addition of a new course in Meteorology (Geology 1). Kighteen courses and half-courses were given in the lecture room and laboratories of the Museum of Comparative Zodlogy by Pro- fessors Shaler and Davis, Assistant Professors R. T. Jackson, Ward and Woodworth, and Drs. T. A. Jaggar, Jr., and R. A. Daly. Mr. J. E. Woodman assisted in Courses 4,5, and 8; Mr. H. C.
