Peru, whence is extracted store of Quicksilver, there is a perpetual spring oi Hot Water, and that not only it is a common complaint there, that the cataracts and fences of the Millers (whereby the water, necessary to drive the Mills, is kept in, that it may be sufficient for the work) are pierc'd through by Mercury, at times thrown in by malicious persons, to the great detriment of the Water and Mills; but also that 'tis notorious, that in some places there are deep under-ground Stoves and Pitts, which, when all others are frozen, steam out of their midst a tepid fume, the inward Bowels of the Earth thus constantly furnishing matter for calefaction, &c.

II. An IDEA of the perfection of PAINTING: originally written in French by Roland Freart Sieur de Cambray, and rendred English by J. Evelyn Esquire, Fellow of the R. Society.

THis excellent Idea, very lately come out of the London-Press, in thin 8°, is drawn in that manner, as that 'tis demonstrated from the Principles of Art, and by Examples conformable to the Observations, which Pliny and Quintilian have made upon the most celebrated Pieces of the Antient PAINTERS; parallel'd with some works of the most famous Modern Painters, LEONARDO da VINCI, RAPHAEL URBINO, JULIO ROMANO, and N POUSSIN.

Those Principles of Art, constantly observ'd by the Antients in their Works, are here enumerated to be five: 1. Invention, or the History. 2, Proportion, or Symmetry. 3. Colour, (wherein is also contain'd the just dispensation of the Lights and Shades.) 4. Motion, in which are express'd the Actions and Passions. 5. The regular Position of the Figures of the whole Work. Of which the Invention and Expression are more Spiritual and refined; the Proportion, Colouring, and Perspective the more Mechanical part of this Art.

The Works, made use of among those of our most eminent Painters, for applying those Principles unto, are 1. the Judgment of Paris. 2. The Massacre of the Innocents. 3. Our Lords descent from the Cross, all three by Raphael. 4. The last Judgement of Michael Angelo. 5. The Repre-
