Scientific Serials

Abstract

THE Botanical Gazette (Indianapolis) for September and October is chiefly occupied by a report of the papers read in the Botanical Section of the American Association for the Advancement of Science at its Ann Arbor meeting. These furnish satisfactory evidence of the good work doing in this branch of science on the American continent, and will not suffer from comparison with a similar record at any of the recent meetings of our own Association. The following are the titles of the papers read:— J. C. Arthur, proof that Bacteria are the direct cause of the disease in trees known as pear blight—C. R. Barnes, the process of fertilisation in Campanula americana.— C. E. Bessey, the question of bi-sexuality in the Zygnemaceæ. —C. E. Bessey, further observations on the adventitious inflorescence of Cuscuta glomerata.—T. J. Burrill, the mechanical injury to trees by cold.—D. H. Campbell, the development of the prothallia of ferns.—J. M. Coulter, on the appearance of the relation of ovary and perianth in the development of dicotyledons.—W. G. Farlow, notes on some injurious fungi of California.—E. L. Sturtevant, an observation on the hybridisation and cross-fertilisation of plants.—E. L. Sturtevant, germination studies.—As far as these papers are reported here, we may note Mr. Arthur's, Mr. Barnes's, Mr. Campbell's, and Mr. Coulter's as giving especially good evidence of a capacity for original work. Another interesting feature of this number is the report of the proceedings of the “Botanical Club,” which held daily meetings during the session of the Association, with an attendance in all of no less than eighty-five members.
