    Notes: [Auszug] DR. N. PETERS, who has done much work already on the peridinians or dinoflagellates, gives a good and detailed survey of the group. It is well known that they combine holophytic with holozoic nutrition and therefore are claimed by both botanist and zoologist. Some apparently feed exclusively as ...

    Notes: [Auszug] IN this lecture, the author points out the difficulties which the accurate specification of colour encounters owing to the physiological nature of the colour sensation. He explains how a colour may be specified by the wave-length of its dominant radiation, its luminous flux, and its coefficient of ...

    Notes: [Auszug] IN the afternoon of Nov. 16, 1929, during my stay in Abisko in northern Sweden (N. lat. 68° 21′) I observed a rather intensive auroral ray of about 10° apparent length and about ½° apparent breadth in the west-south-west below a completely cloudy sky. The exact time of the first observation was ...

    Notes: [Auszug] THE title of this volume suggests a severely technical contribution. It is, in fact, a technical contribution, but one leavened with anecdotal and humorous facts and foibles respecting personalities that figure in its pages. It traces the rise and growth of applied entomology very largely through ...
