IT is affirmed conftantly by many, as an ufuall Experiment, That a Lump 

 o{Ure,m the Bottomeoia Mine, will be tumbled, and ftirred by two Mens 

 ftrength $ which if you bring it to the T op of the Earth, will ask fix Mens 

 ftrength at the leaft to ftirre it. It is a Noble Inftance^ and is fit to be tryed 

 to the full: For it lis very probable, that the Motion of Gravity worketh 

 weakly, both farre from the Earth, and alio within the Earth ; The former, 

 becaule the Appetite of Union of Denfe Bodies with the Earth., in refpec~t 

 ofthediftance, is. more dull ; The latter, becaufe the Body hath in part at- 

 tained his Nature, when it is fome Depth in the Earth. For as for the Mo- 

 ving to a Point or Place (which was the Opinion of the Ancients) it is a meer 

 Vanity, 



IT is ftrange, how the Ancients took up Experiments upon credit, and 

 yet did build great Matters upon them. The Oblervation of fome of the 

 beft ofthem,dehvered confidently, is, That a FefJ'eliiWed with Ajhes, will 

 receive the like quantity ok Water, that it would have done, if it had been 

 empty. But this is utterly untrue, for the Water will not go in by a Fifth 

 part. And I fuppofe,that that Fifth part is the difference of the lying dole, 

 or open 5 of the Aflm ; As we fee that Ajhes alone,if they be hard prefled,will 

 lie in lefs room : And fo the Ajhes with Air between, lieloofer-, and with 

 Water clofer. For I have not yet found certainly, diet the Water, it felf, by 

 mixture of Ajhes,ot 2>«/?,will ihrink or draw into lefs Roome. 



IT is reported of credit, that if you lay good (tore of Kernels of Grapes, 

 about the R cot of a Vine, it will make the fine come earlier and profper 

 better. It may be tryed with other Kernel' ,laid about the Root of a Plant of 

 the fame kind As Figs, Kernels of Apples ,&c. The Caufe may be, for that 

 the Kernels draw out of the Earth Juice fit to nouriih the T re'e' 7 as thofe that 

 j would be Trees of themfelves, though there were no Root ; But the Root be- 

 jingof greater ftrength, robbeth and devoureth the Nouriiliment, when 

 they have drawn itr'As great Fifties dtvoure little. 



Experiments I **jr- He Operation of Purging Medicines, end the Caufes thereof, have been 

 in confort 1 J thought to be agreat Secret And f$ according to the llothfull man- 

 ^f^dkiZs. nerofMen, it is referred to a Bidden Propriety^ Specif call Vertue, and a 

 3 6 Fourth Quality, and the like Shifts of Ignorance, - The Caufes of Purging 

 | are divers-, ail plain and peripicuous, and throughly maintained by Expe- 

 ! rience. The firft is, That whatfotver cannot be overcome and digefted 

 I by the Stcmac is by the Stcmack, either put up by Vomit ^ or put down 

 ] to the Guts • And by that Motion ot Fxpuljion in the Strmack^ and Guts, o- 

 ther Parts of the Body (as the Orifices of the Veins, ?;nd the like) are moved 

 toexpell by Confent. For nothing is more frequent than Motion of Con- 

 \cnt\n the Body of Man. This Surcharge of the Stomach, is caufed either 

 by the Quality of the Medicine^ or by the Quantity. The Qualities are 

 three : Extreme Bitterns in Alois, Coloquintida^c. Loathsome and of hor- 

 rible taft As in Agarick, Black Hellebore, &c. And offecret Malignity, and 

 difagreement towards Mans Body, many times not appearing much in the 

 Taft-, As in Scammony,Mechoacham, Antimony ^,&c.And note well,that if there 

 be any Medicine that Purgeth, and hath neither ot the firft two Mamfeft 

 Qualities -, it is to be heldlfufpe&ed as a kind of ' Poyjon For that it work- 

 eth either by Ccrrofton,or by afecret Malignity, and Enmity to Nature t And 

 therefore fuch Medicines are warily to be prepared, and ufed. The Quantity 

 of that which is taken, doth alfo caufe Purging As we fee in a great Quan- 

 tity of New Milk from the Cow yea and a great Quantity of Meat For 

 - , Surfeits
