ao8 Mifcellanea Curiofa. 



Any one who defires farther Satisfaction in 

 this, may eafily obtain it, if he only put Wa- 

 ter into a clear Glafs Viol, flopping it clofe, 

 to keep Duft and other exterior Matter out, 

 and letting it ftand , without ftining it for 

 fome Days : He will then find a confiderable 

 Quantity of terreftrial Matter in the Water, 

 however pure and free it might appear when 

 firft put into the Viol. He will in a very fliorc 

 time obferve, as I have frequently done, the 

 Corpufcles that were at firft, while the Wa- 

 ter was agitated and kept in motion , fepa-

 by that means forming large thin Manes, ap- 

 pearing like NubecuU, or Clouds in the Wa- 

 ter; which grow more thick and opake, by 

 the continual appulfe and accretion of frefh 

 Matter. If the faid Matter be chiefly of the 

 Vegetable kind , it will be fuftain'd in the 

 Water ; and difcover at length a green Co- 

 lour, becoming ftill more and more of that 

 Colour, I mean an higher and more faturate 

 Green, as the Matter thickens and encreales. 

 That this Matter inclines fo much to that Co- 

 lour 9 is the lels ftrange, fince we fee fo large a 

 fliare of it, when conftituting Vegetables 

 wearing the fame Colour in them. But if 

 there be any confiderable quantity of meer 

 Mineral Matter in the Water, this, being
