《Tetrabiblos》The Signification Of MeteorsClaudius Ptolemy（Ashmand 英譯 1822）
The nebulous mass of the Præsepe in Cancer, and others similar to it, also require observation; as, if in fine weather they appear gloomy and indistinct, or thick, they thereby threaten a fall of rain; but, if clear and in continual vibration, they announce rough gales of wind.[107] Appearances occasionally visible in the sky, resembling the trains of comets,[108] usually indicate wind and drought; in a degree proportionate to their multitude and continuance.
