Abstract
THE Monthly Microscopical Journal for October 1872, contains a continuation of Dr. Robert Braithwaite's papers on bog mosses, the present communication being confined to Sphagnum neglectum Angstr. Dr. J. J. Woodward contributes a reply to further remarks on Tolles 1/5th and Powell and Lealand's 1/16th. This is succeeded by a communication “On the History, Histo-logical Structure, and Affinities of Nematophycus Logani Curr. (Prototaxites Logani Dawson), an Alga of Devonian Age,” by Wm. Cariuthers, F.R.S., in which the author combats the theory advanced by Dr. Dawson, that the fossil in question is coniferous, and contends that it is cryptogamous, belonging to a gigantic alga, of the class Chlorospcrmcæ. Two plates accompany this very interesting and important communication —“On the active part of the Nerve Fibre, and on the probable nature of the Nerve Current,” by Lionel S. Beale, F.R.S., is a further contribution to the researches for which Dr. Lionel Beale has earned a reputation.—“On the Regeneration Hypothesis,” by Dr. Louis Elsberg, of New York. The fundamental proposition of this hypothesis is thus stated by its author: “The germ of every derivative living being contains plastitudes of its whole ancestry.”—Dr. J. J. Woodward contributes some observations on the use of monochromatic sunlight, as an aid to high-power definition.—A short paper by Prof. Albert H. Tutlle, on one of our common monads is from a communication made to the microscopical section of the Boston Society of Natural History.
