sometimes it is caused through cold, or flegme, descending upon the lungs, sometimes it hap∣peneth through heat, dissolving the superflu∣ous matter of the brain, and so through a cat∣tarrhal distillation the cough is excited.
The outward signes,
[ 1] are smoak and dust. If it be caused through a cold distemper,
they spit out nothing while they cough, neither is it so violent, but may be eased by holding the breath, because through holding the breath, the instruments of breathing, that were vexed with cold, do waxe hot, and contrary they are provoked with breathing, oftentimes to cough, their face is pale, and they are not thirsty.
If a hot distemper be the cause,
[ 2] there is felt thirst, and often breathing, do relieve and suc∣cour them; it is also sharp, and more tedious, and they spit but little, this is a thin hot Rhoume distilling from the head to the Tra∣chaea arteria, and sometimes happeneth in the plurisie.
For the cure in a cold cause,
which for the most part happeneth in winter, may be helped with hot things, his neck and feet are to be kept warm,
and oyles of mace, dill, and lillies, be good to anoint the brest; and if he have a ple∣thorick body, give a purgation made by the judgement of the water: If a thin cold Rheume, give penedice, in every sooping they take, and syrrup of oximel is wondrous proper.
If from thin and sharp humours, then ingross it with syrrups of violets, foals-foot, and maidens-hair, and stay the distilling humour with such things,
