accelerated and interglacial mildness is hastened. =Additions to the Missouri Botanical Garden.=--We learn from the ninth annual report of the Missouri Botanical Garden that while the decorative features were maintained in 1897 in about the same manner as heretofore, considerable additions have been made in certain classes, especially orchids, and the collections of cultivated species, with their named varieties, are now estimated to number about five thousand. Circumstances made possible material additions to the contents of the herbarium; and, besides the purchased current collections, rather larger and more numerous than usual, the garden has secured the herbarium of the late J. H. Redfield, very rich in earlier collections representing the flora of the United States; the herbarium of the late Dr. J. F. Joor, containing 4,133 specimens, and largely adding to the representation of the flora of Louisiana and Texas; the interesting herbarium of Gustav Jermy, of San Antonio, Texas, containing a very full set of Carpathian plants and a nearly complete local flora; the important pre-Linnæan herbarium formed by Boehmer and Ludwig; and a Chinese collection by Dr. A. Henry. Even larger additions were made to the library. The instruction of garden pupils was continued, and the garden was visited by several research students. Among the scientific papers accompanying the report and bound with it are those of C. H. Thompson on American Lemnaceæ; N. N. Glatfelter on _Salix longipes_; H. C. Irish on the Genus Capsicum; A. S. Hitchcock on Cryptogams collected in the Bahamas, Jamaica, and Grand Cayman; J. N. Rose on Agaves; C. H. Thompson on Cacti Anhalonium; and seven shorter papers under the heading of "Notes and Observations."
