The most important addition to report in this department is the Herbarium of Professor Abram Sager, A. M., M. D., of the Medical Faculty of the University. Prof. Sager commenced this collection while a Medical Student at New Haven, Conn., continued it while prosecuting his further studies at Troy, New York, and still further increased the collection, in later years, from all portions of the State of Michigan. A private collection, thus accumulated as a work of love, during the progress of a life-time, becomes closely identified with its possessor; and it is impossible for him to part with it without something of a sense of bereavement. The collection should therefore be sacredly preserved in its identity, as a memorial of one of the oldest and most accomplished professors of the University. This Herbarium contains, about 1,200 species, represented by about 5,000 specimens, in a good state of preservation. Rev. L. Holzer, of St. Mary's Church, Detroit, has presented to the University 27 species of plants growing in Michigan, but not heretofore existing in our Collection, nor embraced in any catalogue of the plants of the State. Mr. Holzer has also fur nished a catalogue of 600 species of wild plants found growing in the Southeastern portion of the State-mostly about Detroit. Mr. D. N. Dilla, of California, has presented 12 truncheons, illustrating different species of wood from California and the Sandwich Islands. Summary of Additions to the Museum, during the past year, in Geology, Zoology and Botany. Grand total of additions during the year, 3,965 entries, and 14,264 specimens. On the 2d of October, 1863, I had the honor of submitting to the Board of Regents, a statement of the growth and condition of the Museum, embracing an approximate estimate of the total number of specimens in the various classes. It may be interesting to note the rapid growth of the Museum during the three years past, as shown by the following comparative By a resolution of the Board of Regents, adopted March 29th, 1866, an appropriation of $100 was made to provide 'for the mounting of a portion of the skins in the Zoological Gallery; and, by further action taken June 29th, $250 were appropriated for the same object. Under these provisions Mr. J. T. Coleman has been employed as Taxidermist and Zoological Artist; and he has succeeded in adding very materially to the attractions of the Zoological Gallery. At the same time the mounting of a large number of specimens in their natural attitudes, and surrounded by their natural associations, enhances, in a great degree, the educational value of the Museum. A large new case has been nearly filled with the freshly mounted specimens, embracing many of the old skins, and a large proportion of the fresh additions, already reported. Groups of birds are disposed according to their native habits, over sea-side cliffs or mimic trees, or upon the moss-covered ground; and while the zoological characters are perfectly preserved, to answer the purposes of scientific study, the disposition of the specimens produces a pleasing effect upon the eye. The following is a synopsis of the work done in the Zoolo- gical Department: Old skins of aquatic birds preserved and mount ed on rock-work-including two species of 25 specimens.. Old skins of Wading Birds mounted......... 18 Large group of birds on artificial tree... Old skins preserved and put on exhibition with Large mounted animals repaired and furnished out mounting...... with eyes.... Fresh specimens of Reptiles preserved and mounted... Mounted Birds, renovated and placed in condition for scientific study, (for use of students)........ 19 33 10 66. Various birds repaired and furnished with eyes, 49 All the cases of zoological specimens have also been frequently inspected, and freed from moths and other insects, and preservatives applied. Mr. Coleman has also repaired and cleaned 15 pieces of statuary in plaster and terra cotta, and has cleaned the marble statue of Nydia. The collection of insects, always liable to attacks from va-rious enemies, has been two or three times carefully inspected and renovated. A considerable miscellaneous collection has been generally arranged; and the entire Order of Lepidoptera in the Collection has been re-investigated and relabeled with: greater fullness, with special reference to the wants of students. Besides these special labors, the reception, determination, |
