T is found by Experience, that in Diets ofduaicum, Sarza, and the like, Experiment 

 (efpecially ifthey be fthd) the P^'^ is more troubled in the beginning, ching** " 



Diets. 



than after continuance which hath made fome of the more delicate Sort 

 of Patients, give them over in the midft 5 Suppofing that if thofe Diets 

 trouble them 10 much at firft, they iballnotbe able to endure them to the 

 End. But the Caufe is,for that all thofe Diets,do drie up Humours, Rheums, 

 and the like-, And they cannot Drie up untill they have firft attenuated-, 

 And while the Humour is attenuated, it is more fluid, than it was before, 

 and troubleth the Body a great deal more, untill it be dried up, and con- | 

 fumed. And therefore Patients muft expeel: a due time, and not check at 

 them at the firft. 



T Pi E Producing of Cold is a thing very worthy the Incjuifiti- l ^ x ^ r n i ™ r e c nts 

 on 5 both for Ufe and Difelofure of Caufes. For Heat and touching the 

 Cold are Natures two hands> whereby (he chiefly worketh : And clid:^ 

 Beat we have in readinefs, in refped of the Fire-. But for Cola 

 we muft flay till it comethj or feck it in deep Caves> or high 

 Mountaines • And when all is done, we cannot obtain it in 

 any great degree ; For Furnaces of Fire are farre hotter, than a 

 Summers Sun , But Vaults or Hills are not much Colder than a 

 Winters Froft. 



The firft Meases of Producing Cold, is that which Nature prefenteth us 

 withall -, Namely, the Expiring of cold out of the Inward Parts of the Earth 

 in Winter, whtn the Sun hath no power to overcome it •, the Earth being (as 

 hath been noted by fome {Primum Frigtdum.) This hath been afierted, as 

 well by Ancient, as by Modern Phylofophers : It was the Tenet of Parme- 

 nides. It was the opinion of the Author of the difcourfe in Plutarch, (for I 

 take it , that book was not Plutarchs own ) De primo Frigido. It was the 

 opinion of Telefius , who hath renewed the Philofofhj of Parmenides, and is 

 the beft of the Novelijls. 



Thefecond Caufe of Coldisthe Contact of Cold Bodies For Cold is A- 

 dive and Tranlitive into Bodies Adjacent , as well as Heat: which is feen in 

 thofe things that are touched with Snow or Cold water. And therefore, who- 

 foever will be an Enquirer into Nature, let him refort to a Conservatory of 

 Snow and Ice , Such as they ufe of delicacy, to cool Wine in Summer: 

 Which is a Poor and Contemptible ufe, in refpect of other ufes, that may 

 be made of fuch Confervatories. 



The Third Caufe is the Primary Nature of all T angible Bodies t For it is 

 well to be noted, that all Things whatfoever (T angible) are of themfelves 

 Cold 3 Except they have an Acceflbry Heat by fire, Life, ox Motion ; For even 

 the Spirit of Wwe,ox Chymicall Oyles, which are fo hot in Operation, are to 

 the firft Touch, Cold 5 And Air it felf comprefted, and Condenfed a little 

 by blowing, is Cold. 



The Fourth Caufe is the Denfity of the Body •, For all Denfe Bodies are Col- 

 der than moft other Bodies - 7 As Metals, Stone, Glafi, and they are longer in 

 Heating than Softer Bodies. And it is certain, that Earth, Denfe, Tangible, 

 hold all of the Nature of Cold. The Caufe is, for that all Matters T angible 

 being Coldjt muft needs follow, that where the Matter is moft Congregate, 

 the Cold 'is the greater.
