A diurnal speculum, for the year of our Lord God, 1684 : Being the bissextile, or leap-year, with annual and Mon[thly] predictions & progn[o]stications astrologically handled. (Written and design'd for the press in Aug, 1683. but its publication prevented by the printers t[e]merity.) Wherein was fore-told, in D[e]cemb. 1683. the late and unheard of frost; with the events that may probably and suddenly ensue thereon. By Richard Kirkby, student in astrology and physick.
