The wisdom and power of God are far above not only the first apprehensions, but even the highest ideas of man. And our truest wisdom, and best improvement of knowledge, consist in searching out, and in attending diligently, to what he has actually done: ever bearing in mind those words of the holy Psalmist.[PP] "_The works of The Lord are great: sought out of all them that have pleasure therein._ "_The Lord hath so done his marvellous works, that they ought to be had in remembrance._" POSTSCRIPT. Since these sheets were printed, I have received from Sir Charles Blagden, a present of one of the very small stones mentioned, p. 7, that are affirmed to have fallen in Tuscany; and which has very lately been brought carefully from Italy. Its figure plainly indicates, that in the instant of its formation, there was a strong effort towards crystallization. For it is an irregular quadrilateral pyramid;--whose base, an imperfect kind of square, has two of its adjoining sides about six-tenths of an inch long, each; and the other two, each about five-tenths: whilst two of the triangular sides of the pyramid, are about six-tenths, on every side of each triangle, all of which are a little curved: and the other two triangular sides, are only five-tenths on the sides where these two last join. Its black crust, or coating, is such as has been described in the preceding pages: and is also remarkable, for the appearance of a sort of minute chequer work, formed by very fine white lines on the black surface.
