Occasionall Melancholie

And for her, some sicknesses, in the declination of her yeeres, had opened her to an overflowing of Melancholie; Not that she ever lay under that water, but yet, had sometimes, some high Tides of it; and, though this distemper would sometimes cast a cloud, and some halfe damps upon her naturall cheerfulnesse, and sociablenesse, and sometimes induce darke, and sad apprehensions . . . Occasionall Melancholy had taken some hold in her; Nevertheless, that never Ecclipst, never interrupted her cheerfull confidence, and assurance in God.
