themselves from acquiring support through the ordinary avocations of current industrial life. Very respectfully, CHARLES CROCKER. TORONTO NATURAL HISTORY SOCIETY, Nov. 7.-Henry Montgomery, the president, gave a lengthy address upon "The Relations of the Blastoidea," copiously illustrated by specimens of existing and extinct sea-urchins of various genera, star-fishes, brittle-stars, crinoids, trepangs and Blastoidea of the genera Pentremites and Nucleocrinus. Of the last-named genus the lecturer exhibited the specimen recently described by him in his paper on "A Blastoid found in the Devonian rocks of Ontario." Mr. William Brodie then showed specimens of fiber from the upper sheaths of the "broom" grass, Adropogon scoparius, well adapted for the manufacture of cordage and paper. In his address Mr. Brodie claimed that this grass can be utilized to reclaim dry, sandy, waste land. The samples shown were remarkably tenacious. :0: SELECTED ARTICLES IN SCIENTIFIC SERIALS. AMERICAN JOURNAL OF SCIENCE, November.- Jurassic birds and their allies, by O. C. Marsh. Local subsidence produced by an ice-sheet, by J. W. McGee. Note on the Laramie group of Southern New Mexico, by J. J. Stevenson. The nature of Cyathophycus, by C. D. Walcott. THE GEOLOGICAL MAGAZINE, October.-On some points in the morphology of the Rhabdophora, by J. Hopkinson. The glaciation of the Shetlands, by D. M. Home. Differences between the London and Berlin Archæopteryx, by H. G. Seeley. :0: THE SIXTEENTH VOLUME OF THE AMERICAN NATURALIST.— Although no promises of enlargement were made to our subscribers at the beginning of the year, we beg to call attention to the fact that Vol. xv contains 1042 pages, or 116 pages more than the preceding volume. The number and variety of illustrations is also greater than in the last volume. We can assure our readers that from the papers now in hand and those promised, Vol. xvi will certainly not be inferior in variety and interest to any of its predecessors. There is considerable probability that a department of mineralogy will be shortly added. We would respectfully invite the contributions of original notes and articles, and items of scientific news, and would ask our friends to call the attention of those in any way interested in natural history to our magazine, as an aid and stimulus in their studies and field work. We want to so enlarge our subscription list, that we can offer more illustrations to our patrons. We would respectfully ask our exchanges to specially notice the December NATURALIST, and to send marked copies containing such notices to the editors. INDEX. Bathybius, 813. Bathyopsis fissidens, 75.
