A Cyclone

In examining cyclones, phenomena occasionally present themselves which strongly suggest the idea that they include within their circuit, as an independent meteor, the whirlwiud or the tornado, the phenomena in question being most frequently met with in those cyclones which present, in close continuity, masses of air aiffering very widely from each other in temperature and humidity, Of such cyclones the great storm of October X4th last appears to be one. On that occasion the changes of temperature and humidity were sharp and sudden, particularly from the Grampians to the Cheviots, the great fall occurring when the wind changed to northward. Off the Berwickshire coast the darkness accompanying the changes of wind, temperature and humidity, was denser and more threatening than elsewhere, and, almost simultaneously with the proachof these changes, a hiimcane, or rather tornado, broke out with a devouring energy which bore everythiug before it. The tomado character of the storm off Eyemouth is shown by the accounts of some of the survivors, who describe the wind as blowing straight down from the sky with an impetuosity so vehement and overmastering that the sea for some extent was beaten down flatintoa stretch of seething foam, in which many boats sank as if driven down beneath the foam by the wind, while outside this tract the waves seemed to be driven up to a height absolutely appalling, which in tlieir turn engulfed many of the boats yet remaining. Similar seas, with level wastes of seething foam, bounded nnmediately by wave3 of a lieight and threatening aspect never before witnessed, were encountered by several well-appointed steamers out in the middle of the North Sea during this storm, thus conflrming the observations of the Eyemouth fishermen. These facts seeni to point to one or perhaps more tornadoes of no inconsiderable dimensions, with slanting columns, the terrible force of the gyrations of whose lower extremities played no inconspicuous part in the devastation wrought during the continuance of this able storm.
