Page 584 - At 8h 20™ it formed an inverted cone, with the apex, apparently 1£° wide, pointing to the horizon, and the base about 3£° wide with an altitude of 60°. At this period it became very peculiar in its external properties, forming a large column, of a clear silvery lustre, destined to span the heavens in one entire arch. Its progress in this form became steady and regular, but slow, until it reached the meridian, when it commenced to form another inverted cone, with the apex pointing due west....

Page 584 - At about 8h 40™ it became a most superb object : the brightness of its white light was so excessive as to drown the Via Lactea, and its form a double cone, each cone with a double curve, best described as resembling the form of the diatom Gyrosigma elongatum under the microscope, the aurora having a dark line, as in the Navicula, running along its centre, in diameter about 5...
Page 171 - Annahme 1. allein erfordert für m und v (Maximalbeträge der Lotschwankungen in der Komponente des Meridians und des ersten Vertikals) jährliche Perioden, welche sich je nach der Breite bedeutend unterscheiden. 5. Die Verspätung von m und v im nördlichen Winter, die Verfrühung im Sommer rührt von der verschieden schnell entstehenden Aufwölbung der Erdoberfläche durch ungleiche Wärmemengen her; dagegen ist ein Teil der Verfrühung von v schon ein Erfordernis der Theorie allein.
