It is fortu. nate for a country, and honourable to its government, when qualities and dispositions like these are placed in high and influencing stations.

State of the argument. IN crossing a heath, suppose I pitched my foot against

a stone, and were asked how the stone came to be there : I might possibly answer, that for any thing I knew to the contrary, it had lain there for ever : nor would it perhaps be very easy to shew the absurdity of this answer.

To reckon up a few of the plainest of these parts, and of their offices, all tending to one result:~We see a cylindrical box containing a coiled elastic spring, which, by its endeavour to relax itself, turns round the box. We next observe a flexible chain (artificially wrought
