SECT. II. Concerning Air and Water.

1 COld Air and washing with cold Water, does heat robust Bodies, but refrigerates weak ones.

2 Warm Air and warm washing unless Crudities gain-stand, help Perspiration, and refrigerate the internal Bowels.

3 Water that is heavy and Air that is foggie, turn the perspirable Matter into an Ichor or sharp Matter; which for the most part causes a Cachexy, or evil disposition of the Body.

4 In a cold and clear Air Perspiration is likewayes stoped, because the Pores are condensed: Yet because the Fibres are also roborated, therefore the retained perspirable Matter is neither felt, nor does hurt.

5 In a foggie Air the perspirable Matter is retained, and the Pores are filled, and not condensed, and the Fibres are relaxed, and

not roborated: And therefore the perspi∣rable Matter retained both hurts and is felt.

6 A cold superveening to a warm day, especially the usual quantity of drink being taken, stops about a third part of the Per∣spiration that day.

7 Weak persons are most hurt by the sudden approach of cold.

8 A pleasant Cool coming upon Bodies heated, hurts them more then the greatest coldness of Air or Water; because the first obstructs and relaxes the Pores; and the last obstructs and ••oborats them.

9 A pleasant ••outherly Air with violent exercise, is oft times very dangerous; for the Air brings the stoping of the Perspiration, and the exercise brings the acrimony thereof.

10 Weak persons in the Winter evacuat the Perspirable Matter retained by Urine, and robust Persons in Summer.

11 Long Droughts are wholesomer than continual Rains, for they make the Body lighter.

12 In the Summer we are troubled with heat, not because of the heat of the Air, for every place of our Body is hotter then the Air; but because the Summer Air does not sufficiently concentrat the inter∣nal heat; but suffers it to diffuse, whereby

it is less powerfull to dispel the perspirable Matter; which being retained becomes A∣crimonious, and so becomes troublesome to us.

In the Summer in the day time, but in the Winter in the night time, robust Bo∣dies perspire most.

14 Want of Perspiration in the Summer brings a Maligne Fever; but in the Winter scarce brings any hurt: The perspirable Mat∣ter retained turning far sooner Acrimonious in the Summer, than in the Winter.

15 Sleeping in the open Air in the Sum∣mer with the Body uncovered, hindering very much Perspiration, proves exceedingly dangerous.

16 The perspirable Matter retained, is not apt soon to hurt the internal Bowels, unless it become acrimonious by external heat, by violent motion, or by its long stay.

17 The hurt of immoderate Venery is in some manner alla••ed by cold immediatly succeeding heat, which concentrats the inter∣nal heat.

18 In the Summer nights by the varie∣ty of the temper of the Air, Bodies are ve∣ry much disposed to Fevers.

19 From the Autumnal Equinoctial, until the Winter So••••tice, there is every day about

a pound of perspirable matter retained.

20. Autumnal Diseases shall be escaped, if your body be not of more weight in Autumn than it was in Summer.

21. You shall be troubled with no Dis∣ease in the autumn if ••ou meet the superve∣nient cold with sufficient clothing, and by the use of Diureticks, keep the body in the same weight it was before.

22 Those that are troubled with diseases in the Winter arising from the plenty of humors, are to be purged in the Autumn, but not in the Spring: and are to be brought to the weight that they had in the begin∣ning of Summer.

23 When Diseases come from an evil quality, the Body is to be purged in the Spring; for the Summer increases most the evil quality.

24 Those that throw off their cloaths early in the Spring, or are too long in put∣ting them on in the Autumn, do fall into Fevers in the Summer, and into Distillations and Defluxions in the Winter.

25 Health would be preserved even to the extremity of Age, if the Body were kept in an usual weight all the four Sea∣sons of the year.

26 The increase of weight is alwayes in

the beginning of Autumn, and the diminu∣tion thereof in the beginning of Summer; and there is more danger in the increase, than in the diminution.

27 Air too moist or windie hinders Perspiration.
