Abstract
THE American Naturalist for October 1871 commences with a paper by Dr. Jeffreys Wyman entitled, “Experiments with Vibrating Cilia,” the chief points in which are some determinations of the rate of movement of the vibrating cilia on the gills of Mollusca, both in air and in water, and the description and drawing of an instrument by means of which this rapidity can be measured and exhibited so as to be seen over a large lectureroom. Prof. James Orton furnishes some contributions to the Natural History of the Valley of Quito (continued in the next number); and Dr. J. S. Billings contributes a paper on Hysterium, a genus of Ascomycetous Fungi, and some of its allies, illustrated by a plate. Mr.T. Martin Trippe has a very interesting paper on some differences between Eastern and Western Birds, in which he traces the difference in habits, note, time of breeding, &c., in the same species of bird in the eastern and newly-settled western portions of the American continent, and the manner in which the indigenous avifauna of the Western States is becoming gradually superseded by eastern forms, along with the advance of man.
