To THE PRESIDENT AND FrLLows OF HARVARD COLLEGE: — Throughout the Academic year, 1904-1905, eleven courses in Zodlogy were given, by Professors Mark, Jackson, Parker, Castle, and Dr. Rand, to students in Harvard University, and four courses to students of Radcliffe College. The assistantsin the University courses were Messrs. M. W. Blackman, L. J. Cole, Manton Cope- land, N. C. Davis, I. A. Field, A. D. Howard, and H. E. Walter ; in those given for Radcliffe College, Mr. A. S. Pearse and Miss Edith N. Buckingham. During the summer, seven students carried on work at the Laboratory of the U. S. Fisheries Bureau at Woods Hole, and twelve persons, six connected with Harvard University, availed themselves of the facilities offered- by the Bermuda Biological Station for Research. The incomes of the Humboldt Fund and the Virginia Barret Gibbs Fund have been applied, as in late years, for the benefit of students con- nected with the Zoédlogical Laboratory. In the Department of Geology and Geography, Professor Davis, as Sturgis-Hooper Professor of Geology, conducted two courses, one of research elected by two students, and a second, open to graduates and undergraduates, given to fifteen students. Mr. Isaiah Bowman was assistant in the second course. The geologi- cal courses, other than those of Professor Davis, were given by Professors Shaler, Jackson, Ward, Woodworth, Jaggar, and Dr. Smith, assisted by Messrs. A. H. Gale, Augustus Locke, G. R. Mansfield, H. E. Simpson, and S, A. Starratt. These courses, nineteen in number, were attended by 460 students of Harvard University ; the four courses in Radcliffe College were taken by 40 students. In the Summer School, Professor Shaler and Dr. Smith of the Geological Department, and Prof. J. E. Woodman of Dalhousie College, Halifax, gave two courses to eighteen stu- dents. Prof. J. B. Woodworth’s course in advanced field work in the Rocky Mountains of Montana was taken by three students. 4 ANNUAL REPORT OF THE The Museum is indebted to Messrs. Bangs, Brewster, Faxon, and Woodworth for the care they have taken of the collections under their charge. The accompanying special reports give the details as to the additions received and the work accomplished | during the year. Of the collections received, mention should be made of the valuable series of Vertebrates from Gorgona Island, Colombia, the Pearl Islands, Bay of Panama, and from the vicinity of the city of Panama, presented by Mr. John E. Thayer, and of the collections, chiefly entomological, presented by Mr. A. A. Packard. Mr. Packard’s father, the late Professor A. S. Packard, a graduate of the Lawrence Scientific School, and a student of, and assistant to, the founder of this Museum, was connected for many years (1867-1878) with the Peabody Academy of Science of Salem, and later, from 1878 until his death in February, 1905, with Brown University. Professor Packard bequeathed to the Museum a complete set of his scientific publications, other than books, and left the disposition of his collections to his son. Throughout his life, Professor Packard was an ardent accumu- lator of material and a prolific author. His collections, with many types, gathered during his residence in Salem, have been the property of the Museum since 1885, and Mr. Packard, recog- nizing the advantages to his father’s fame and to future investi- gators, has given the Museum the collections amassed by his father since 1878. We are also indebted to Messrs. Allen, Barbour, and Bryant for the larger part of the specimens col- lected during their explorations of the Bahamas; to Mr. Addison Gulick for a series of Bermudian land shells, fossil and recent, and to Professor W. W. Coe for a number of Nemerteans from the west and northwest coasts of America. The specimens selected for the Exhibition room devoted to the Palaeozoic faunae, have been arranged, and the room has been opened to the public during the past year. The three cases on the south wall of the room are filled with Vertebrates; the other wall cases and those of the central floor space, equal in all to twenty-seven cases, are given over to the Invertebrates. The richness of the Museum collections in Palaeozoic fossils will make this room, when the material is completely mounted and labelled, fairly representative of the older faunae and of much general in- terest. The casing of the Exhibition room for the Mesozoic faunal collections has been completed, and a beginning made in MUSEUM OF COMPARATIVE ZOOLOGY. 5 the selection of representative species. The floor case shows the cast of Jguanodon bernissartensis, from the Wealden of Belgium, as the central feature, with casts and portions of the skeletons of Dinosaurs and of Vertebrates, other than Fishes, around it. The Fishes and a few other Vertebrates occupy the wall cases on the north side of the room, while the Invertebrates will be displayed in the cases on the south side, and the large table cases on the east and west sides. Considerable wall space, outside of the cases, is used for many of the more bulky Vertebrates. To the African faunal room there has been added, by purchase from Rowland Ward, a fine male of the South African Ostrich, Struthzo australis, and a magnificent male Hippopotamus from the Mosello River, Zambesi; the latter, an excellent example of modern taxi- dermy, is nearly maximum size for the species, and with the Giraffe received in 1903, makes an effective exhibition of two characteristic African Mammals. The principal other additions to the exhibition collections consist of the Reptiles mounted by the Museum preparator, Mr. George Nelson; of these, twenty- eight have been added, the more notable being a group of the Mexican Heloderma, H. horridum; one of the Bahama Iguana, Cyclura baeolopha, and a fine Boa, B. constrictor. For the Boa and the Iguanas we are indebted to the interest of Mr. Thomas Barbour ; the Helodermas were obtained in eben: from the Bierichn Museum of Natural History. The U.S. Fish Commission Steamer “Albatross,” under the com- mand of Lieut. Commander L. M. Garrett, U.S. N., was placed at the disposal of Mr. Agassiz, and was occupied with deep-sea work in the Hastern Tropical Pacific from October, 1904, until March, 1905. Mr. Agassiz was accompanied by Prof. C. A. Kofoid of the Uni- versity of California, Mr. H. B. Bigelow, and Mr. Magnus Wester- gren of the Museum. The cruise extended from San Francisco to Panama, from Panama to the Galapagos, and thence to Aguja Point. From Aguja Point, the “ Albatross” worked towards the western edge of the Chili-Peruvian Current, then east through the Milne Edwards Deep to Callao. Leaving Callao on December 34, Kaster Island was reached on the 15th. Considerable shore work was done at Easter Island, and on January 3, 1905, the “ Albatross” arrived at Wreck Bay, Chatham Island, Galapagos. From Wreck Bay, the cruise continued to Manga Reva, and from that place to Acapulco, which was reached February 24th. Mr. Agassiz’s letters, written during the voyage, have been published 6 ANNUAL REPORT OF THE in the Bulletin, Vol. 46, No. 4. They give a preliminary report of the cruise; a more extended account, with charts and illustra- tions, will be published in an early issue of the Memoirs. The collections arrived safely and have been distributed to thirty-four specialists. The reports on the scientific results will appear chiefly in the Bulletins and Memoirs of the Museum. The library of the Museum consists of 41,157 volumes and 30,033 pamphlets ; the accessions for the year are 1,982 volumes and 1,607 pamphlets. The publications for the year include two volumes and one number of the Memoirs, one volume and nine numbers of the Bulletin, and the Annual Report. The two volumes of the Memoirs (Volumes 30 and 81) contain the Reports on the col- lection of Panamic deep-sea Echini by Mr. Agassiz, and the Star- fishes by Professor Ludwig, made by the “ Albatross ” expedition of 1891. Together, these volumes make one of the most exten- sive publications that the Museum has yet issued. Mr. Springer’s Memoir on Cleiocrinus describes and figures, in detail, one of the earliest of known Crinoids, and one of most intricate structure. Of the nine numbers of the Bulletin, four numbers contain reports on the scientific results of the expeditions of the ‘‘ Albatross,” two on the one of 1891, and two on the recent cruise in the Eastern Tropical Pacific; one number is a report upon some of the results of Mr. Agassiz’s expedition to the Maldives; one is a contribution from the Zodlogical Laboratory, and one a contribu- tion from the Geological Laboratory; one number deals with Museum collections, and one volume and one number are based primarily on Museum collections. The Corporation has granted an appropriation of $350.00, to assist in the publication of Con- tributions from the Zodlogical and Geological Laboratories, and Mr. Agassiz’s generous interest provides for the publication of the Memoirs and Bulletins which contain the reports on the scientific results of the expeditions connected with his work. The appointment of Professor Hubert Lyman Clark, as as- sistant in Invertebrate Zodlogy, supplies a long-felt want; there is, however, urgent need for assistants in Invertebrate Palaeontol- ogy, in Entomology, and in Ornithology. SAMUEL HENSHAW. MUSEUM OF COMPARATIVE ZOOLOGY. 7 REPORT ON THE ZOOLOGICAL LABORATORY. By E. L. Marx. Ty accordance with the custom of previous reports the number of students in the several courses in Zodlogy during the academic year 1904—05 and their distribution by classes is given in tabular form, the numbers printed in italics referring to students of the Lawrence Scientific School. 22+4/40+3)| 45+5 | 8413 152+ 32=184 7+1,;14+6)| 1 4 380+ 11= 41 44+4) 3+1 4+1/| 1 21 15 441 HM UE TE Ee See WW Coegg Sums 55 Suny owas 59+12| 4645 | 8+ 22 2 258 + 67 = 825 Similarly the following table shows the number of students of Radcliffe College who took courses in Zotlogy : — Fresh. | Spec. Dr. Alexander Petrunkévitch, who was approved as Docent in Zo- ology to lecture on Cytology in the second half-year, was com- 8 ANNUAL REPORT OF THE pelled by serious family sickness to leave Cambridge in the middle of the year, and was therefore unable to give the course. Other- wise the instruction given did not differ from that of the preced- ing year, except in so far as concerned alternating courses. Diagrams and demonstration material used principally in Courses 1 and 2, which had hitherto been arranged in cases on the fourth floor, were transferred to the first-floor lecture-room and renumbered to correspond with their places in new cases. This resulted in saving time both to the instructors and the janitor. After the announcement of courses in Zoédlogy for 1904-05 had been issued Gm July 1904) an arrangement was made which allowed the Department to retain the services of Dr. H. W. Rand. The serious curtailment of the work in Zodlogy which had been impending — necessitating the withdrawal of Course 13 and the reduction of Zodlogy 3 to a half-course, to be given by Professor Parker — was thus averted, and it was possible to restore the courses to the same form which they had had in previous years. The lectures in Zoology 1 were given by Professor Parker, who, as usual, gave systematic attention to supervising the laboratory work and to the training of the assistants who aided him in this important part of the course. The chief assistant in the course in Harvard University was Mr. Leon J. Cole, Austin Teaching Fellow ; the sub-assistants were Messrs. H. KE. Walter, M. Cope- land, and N. C. Davis. In Radcliffe College the chief assistant was Mr. A. 8S. Pearse, the sub-assistant, Miss Edith N. Bucking- ham. Owing to the loss in previous years of a certain amount of microscopic apparatus, it was decided to institute an inspection of this apparatus at the close of each laboratory period. This re- sulted in entirely preventing such loss. In Zodlogy 2, by Professor Castle, the lectures were increased to forty, and a certain amount of time each week was devoted to oral reviews of topics discussed in previous lectures. More time than heretofore was also given by the instructor to personal super- vision of the laboratory exercises, thus enabling him to become better acquainted with the work of individual students. Mr. A. D. Howard, Austin Teaching Fellow, was chief assistant in the course, and Mr. M. W. Blackman was sub-assistant. Zodlogy 38, possibly owing to the announced change in its nature and the subsequent restoration of it to its former scope, was not so largely elected as in the preceding year. One gradu- _— MUSEUM OF COMPARATIVE ZOOLOGY. i) ate took the work for the first half-year without being enrolled ;. on the other hand three of those enrolled were dropped before the end of the year. The plan of devoting occcasionally a lecture hour to aconference on previous work, instead of a formal lecture, resulted in giving to some of the poorer students an increased in- terest in the work, and is thought by the instructor, Dr. Rand, to be worthy of further trial. A new edition of the Outline of the Laboratory Work in this course was prepared by Dr. Rand and published by the Harvard Codperative Society. This outline on the Comparative Anatomy of Vertebrates, originally pre pared by Professor Parker, has been revised and considerably amplified by Dr. Rand in the new edition. The assistant in this course was Mr. I. A. Field. Zoslogy 4 and 5 were given substantially as in the preceding year, Dr. Rand having charge of the laboratory work and giving in Course 4 a few of the lectures on the anatomy and histology of the Hirudinea. Zoblogy 8 and 9 were given by Professor Jackson. Several specimens useful for students in Palaeozodlogy were purchased from Ward’s Natural Science Establishment, and others were re- ceived from students in the Department. Six of the eleven students enrolled in Zodlogy 10, under Pro- fessor Castle, were allowed to take the lectures without laboratory work, and to count this as a half-course. The remaining five were occupied with the investigation of special problems, mainly questions of inheritance, and the results of their studies will be presented later for publication. Two of the five met the labora- tory requirements of this course by giving additional time to the work selected for investigation in Zodlogy 20. Contribution 164 was based on work done in part in connection with this course in a previous year. | In Zodlogy 18, by Professor Parker, both lectures and labora- tory exercises were substantially the same as in 1903-04; but in Zodlogy 16 the lectures were thoroughly revised. The laboratory work in Course 16 consisted, as heretofore, of separate research topics. In four cases these were identical with the topics of the same students in Zodlogy 20. In some of the other seven cases the results reached are to be presented for publication. Contri- butions from the Zodlogical Laboratory numbered 161 and 162 represent work done in this course or its companion course (Zodl- ogy 15), and 1638 is based on experiments conducted under the 10 ANNUAL REPORT OF THE supervision of Professor Parker at the Laboratory of the U. 8. — Fisheries Bureau at Woods Hole. | Fifteen students pursued research problems in Zodlogy 20, three under the direction of Professor Castle, four under Profes- sor Parker, seven under Professor Mark, and one under Profes- sors Parker and Mark jointly. As already stated, in the case of six of the students working under the direction of Professors Par- ker and Castle, the laboratory requirements of the more formal : courses were met by devoting the laboratory time to the research : work of Zoédlogy 20. Mr. M. W. Blackman completed two papers, one of which he presented as a thesis for the Doctor’s degree, the other being on The Spermatogenesis of the Myriapods. IV. On | the Karyosphere and Nucleolus in the Spermatocytes of Scolo- — pendra subspinipes. | The work of several students is nearly ready for publication and that of others is well advanced. The degree of Doctor of Philosophy was conferred in June, 1905, on Mr. Maulsby Willett Blackman, whose thesis was en- titled The Spermatogenesis of the Myriapods. III. The Sper- matogenesis of Scolopendra heros. Besides giving critical supervision to all the papers appearing as Contributions from the Zodlogical Laboratory and from the Bermuda Biological Station for Research, Professor Mark has published an address prepared for Section F. (Zodlogy) of the American Association for the Advancement of Science, the title of which appears in the list of Contributions from the Bermuda Station.

Ulrich, He also supervised the work the results of which are embodied in Contribution No. 167. Dr. Petrunkévitch has published, as No. 160 of the Contribu- tions from this Laboratory, a-paper on Natural and Artificial Parthenogenesis, presented before Section F (Zodlogy) of the American Association for the Advancement of Science at its meeting in Philadelphia. It is a matter of deep regret to the Department that Dr. Petrunkévitch is compelled to remove from Cambridge and give up his connection with the Laboratory. The Virginia Barret Gibbs Scholarship was reassigned for 1904-05 to Mr. John H. McClellan. Of the five persons carrying on work at Woods Hole during the summer of 1904, two received aid from the Humboldt Fund to the amount of $22.85, and of the six working at the Bermuda Station one received from the same source $70.00. During the summer of 1905 seven students carried on work at the United States Fisheries Bureau in Woods Hole, three of them being employed as assistants in the work of the Bureau. Five students received aid in the summer of 1905 from the Humboldt Fund, amounting to $132.85, four while working at Woods Hole, and one at Cambridge. Professors Castle and Mark have received renewals of grants from the Trustees of the Carnegie Institution of Washington to aid in the study of questions in heredity. The meetings of the Zodlogical Club were held on the after- noons of Mondays throughout the year, and the topics under discussion were announced in the Calendar. There were twenty- five meetings, and fifty-five papers were presented ; thirty-two of _ them were summaries of original work. 12 ANNUAL REPORT OF THE Three numbers of the Contributions from the Bermuda Bio- logical Station for Research have been published since those recorded in the report for 1903-04 : — No. 4.

Professor Parker was appointed Acting Director of the Ber- muda Biological Station for Research for the summer of 1905. Besides Mr. John F. Cole, who carried on for the Station mag- netic observations during the months of March and April, there were twelve biologists enrolled. Of these, seven were University instructors, three in Harvard and one each in the University of Pennsylvania, the University of Cincinnati, Washington [State] University and Syracuse University. The conditions which necessitated retrenchment during the year 1903-04 still continue, and weigh heavily on the Department. It is proposed to amplify somewhat in the future the instruction in some of the courses by presenting in alternate years different portions of the fields now more or less completely covered each year. For the coming year Professor Mark’s lectures on Embry- ology of Vertebrates will be devoted to Organogeny (Zodlogy 6), leaving the Early Stages of Development (Zodlogy 5) for 1906-07. In like manner Professor Parker’s lectures on Com- parative Histology will deal with Epithelial and Nervous Tissues in 1905-06, and with Muscular and Sustentative Tissues the following year. Professor Castle proposes to divide each of his alternating courses (Zodlogy 10 and 11) into half-courses (10a, 106, and 11a, 116), which may be taken separately, and to change somewhat the ground covered. Course 11a, to be given in the first half of the coming year, will be devoted to Variation, Heredity, and the Principles of Animal Breeding.

MUSEUM OF COMPARATIVE ZOOLOGY. 15 REPORT OF THE STURGIS-HOOPER PROFESSOR OF GEOLOGY. By WI tui1am M. Davis. THE usual courses of instruction have been given during the past year. The course on the Physiography of the United States, open to undergradutes and graduates in the second half of the year, has been improved with the aid of Mr. I. Bowman, assistant, by the development of a systematic series of laboratory exercises, based chiefly on the topographical maps of the United States Geological Survey.. The advanced course, primarily for gradu- ates and extending through the year, has been conducted as here- tofore, each student selecting a special problem and reporting upon his work at regular meetings of the class. ~ During the autumn a share of my time was given to the pub- lication of a report on the journey to Turkestan that was under- taken two years ago under the direction of Mr. Raphael Pumpelly as leader of a Carnegie Institution expedition. A meeting for organization of the American Association of American Geogra- phers, in preparation for which there was much correspondence, was held in Philadelphia Christmas week; this association ap- pears to be the only geographical society in the world in which membership is limited to persons of some degree of expert knowledge and performance. During the period of the mid-year examinations, a short course of lectures on physiography was given at the Johns Hopkins University in Baltimore. An inter- collegiate excursion was organized to visit the glacio-marginal channels in the uplands near Syracuse, N. Y., during the April recess. Special attention has been given during the year to three problems, concerning which essays have been or will soon be published: the bearing of physiography on Suess’s theories, in which certain observations made in the Tian Shan Mountains in 1905 were discussed; the problem of fault-block mountains, based on a continuation of the work of earlier years and referring 16 ANNUAL REPORT OF THE particularly to the results of an excursion to certain ranges in the deserts of Utah in 1904; and the peculiar features of the geographical cycle in an arid climate, with special regard to the work of Passarge on the Kalahari Desert. A week was given early in July to the cuidance of a party of students and professors forming an intercollegiate summer geo- logical course through the valleys of the Susquehanna and the Juniata in central Pennsylvania. On July 15 I sailed from New York to join the official party of the British Association on its excursion to South Africa, as a result of which my return to Cambridge will be delayed somewhat beyond the beginning of the next academic year.

The accounts are annually exam- ined by a committee of the Overseers. The only funds the income of which is restricted, the Gray and the Humboldt Funds, are annually charged in an analysis of the accounts, with vouchers to the payment of which the income is applicable. The income of the Gray Fund can be applied to the purchase and maintenance of collections, but not for salaries. The income of the Virginia Barret Gibbs Scholarship Fund, of the value of $250, is assigned annually with the approval of the Faculty of the Museum, on the recom- mendation of the Professors of Zoology and of Comparative Anatomy in Harvard University, ‘‘in supporting or assisting to support one or more students who may have shown decided talents in Zodlogy, and preferably in the direction of Marine Zoology.” The income of the Humboldt Fund (about $300) can be applied for the benefit of one or more students of Natural History, either at the Museum, the United States Fish Commission Station at Wood’s Hole, Bermuda, or the Tortugas. Applications for the tables reserved for advanced students at the Wood’s Hole Station should be made to the Faculty of the Museum before the lst of May. Applicants should state their qualifications, and indicate the course of study they intend to pursue. ] y y - - » z er eer a »! f he » ‘ Li ae Le - ‘ - ‘ ee we sy ‘ | f . \ a ‘ + ; r ' r Was : nm _ - i y ‘ ) . : a . a oy - 1 4 sy f p oe ew ; . . 3 a - ss we ea eS A Vee? ‘ : = ee? x 4 by % The following Publications of the eee of Comparative Zodlogy are in preparation : — Reports on the Results of Dredging Operations in 1877, 1878, 1879, and 1880, in charge of ALEX- ANDER AGASSIZ, by the U.S. Coast Survey Steamer “ Blake,” as follows: — H.
