_Water_, according to your _Authors_ opinion,[1] _is frozen into Snow, Ice, or Hail, not by Cold, but by its own Gas._ But since I am not able to conceive what his Gas is, being a term invented by him self, I will briefly declare my own opinion, which is, That Snow, Ice, and Hail, in my judgment, are made in the like manner, as Passions or Colours are made and raised in Man; for a sad discourse, or a cruel object will make a Man pale and cold, and a fearful object, will make him tremble; whereas a wanton and obscene discourse will make some red and hot. But yet these discourses and objects are onely external, occasional, and not immediate efficient causes of such alterations. Also when a Man eats or drinks any thing that is actually hot or cold, or enters into a cold or hot room, bath, or air, he becomes hot or cold by the actions of those external agents that work upon him, or rather whose motions the sensitive motions of his body do pattern out. The like for diseases; for they may be caused either by hearing ill reports, or by taking either hurtful or superfluous food into the Body, or by Infections inwardly or outwardly, and many other ways. Likewise may Colours be made different ways; And so may Snow, Ice, and Hail; for all loose, rare, and porous Bodies are more apt to alter and change then close, solid, and dense bodies; and not onely to change from what they are, but to rechange to what they were. But, _Madam_, many studious persons study Nature more in her own substance, then in her various actions, which is the cause they arrive to no knowledg of Natures Works; for the same parts of Matter may act or work several ways: Like as a Man, or other animal creature, may put one part of his body into various and several postures, and move it many different ways. Your _Author_ may say, that although several Creatures may be changed to our sight or perception, yet they are not really changed in Nature. I answer, Their Principle, which is a natural matter, of which all Creatures are made, cannot be changed, because it is one, simple, and unalterable in its Nature; but the figures of several Creatures are changed continually by the various motions of this matter; not from being matter, but onely from such or such a figure into another; and those figures which do change, in their room are others produced to keep up the certain kinds of Creatures by a continual successive alteration. And as there are changes of parts, so there are also mixtures of several parts, figures and motions in one and the same Matter; for there are not different kinds in the nature of Matter: But, although Matter is of several degrees, as partly animate and partly inanimate, and the animate Matter is partly rational, and partly sensitive; Nevertheless, in all those degrees it remains the same onely or meer Matter; that is, it is nothing else but Matter, and the onely ground in which all changes are made. And therefore I cannot perceive
