together: which appeared! in the very definition of ic, for, to he 

 le$e divisible, (which is the notion of dcnfity) ipeaketh a refi- 

 ftance to divifion, or a Ricking together. 



Now let us examine how two parts of different Elements arc 

 joyned together, to make a compound. In this conjunction we The third con- 

 find both the effects we have already touched :for,t wo fjch parts '^'^ l* f 

 mutt make one and moreover, they nmft havefome refinance rent Element*, 

 todivifibilhy. The firft of thcfceffeA* we have already afligncd l^K^' 

 unto the nature of quantity . And ic being the formall effect of city and deirfty 

 quantity; it cannot (whereloever it is found) have any other for- tosct er * 

 mall caufe then quantity : and therefore cither the two .little 

 parts of different Elements, do not become one body : or if they 

 do, we muft agree that it is by the nature of quantity which 

 worketh as much in heterogeneall parts, as in doth in homoge- 

 neall ones.And it muft needs do fo: becaufe Rarity and Deniity 

 (which are the proper differences of Quantity) cannot change 

 the common nature of Quantity, that is dicir Genus : which by 

 being fo to them, muft be univocaiiy in them both. And chis ef- 

 fect cometh precifely from the purs notion of the Genus : and 

 confequemly, muft be feen as well in two parts of different na- 

 tures, as in two parts of the fame nature : buc in parts of the 

 fame nature,which once were two, and afterwards become one ; 

 there can be no other reafon why they are one, then the very 

 fame for which thoic parts that were never feparated fbut that 

 may be feparated) are likcwife one : and this, moft evidently, is 

 the nature of quantity. 



Experience feemeth to confirm thus much; when pouring wa- 

 ter out of a bafin, feme of it will remain fticking to the fides of 

 the metall : for if the quantity of the bafin, and of the water, 

 had not been one and the fame by its cr.vn nature ; the water 

 (considering the pliablencfTe of its parts ) would certainly have 

 comaien all away, and have glided from the uncvennedc of the 

 bairn, by the attractive unity of its whole, and would hive pre- 

 ferred the unity of its quantity within it felf, rather then by 

 fticking to the bafin, have fuffered divifion in >ts own quancitic; 

 which we are fure was one, whiles the water was altogether in

the bafin :but thatjboth the bafin and the water making but one 

 quantity; and a divifion being unavoydable in that one quan- 

 tity;ic was indifferent, i regard of the quantity confidercd finely
