We entered Scotland by a frightful moor of sixteen miles, which promises very little for the interior parts of the kingdom; but the prospect mended as we advanced. Passing through Dunbar, which is a neat little town, situated on the sea-side, we lay at a country inn, where our entertainment far exceeded our expectation; but for this we cannot give the Scots credit, as the landlord is a native of England. Yesterday we dined at Haddington, which has been a place of some consideration, but is now gone to decay; and in the evening arrived at this metropolis, of which I can say very little. It is very romantic, from its situation on the declivity of a hill, having a fortified castle at the top, and a royal palace at the bottom. The first thing that strikes the nose of a stranger, shall be nameless; but what first strikes the eye, is the unconscionable height of the houses, which generally rise to five, six, seven, and eight stories, and, in some places (as I am assured), to twelve. This manner of building, attended with numberless inconveniences, must have been originally owing to want of room. Certain it is, the town seems to be full of people: but their looks, their language, and their customs, are so different from ours, that I can hardly believe myself in Great-Britain. The inn at which we put up (if it may be so called) was so filthy and disagreeable in all respects, that my uncle began to fret, and his gouty symptoms to recur--Recollecting, however, that he had a letter of recommendation to one Mr Mitchelson, a lawyer, he sent it by his servant, with a compliment, importing that we would wait upon him next day in person; but that gentleman visited us immediately, and insisted upon our going to his own house, until he could provide lodgings for our accommodation. We gladly accepted, of his invitation, and repaired to his house, where we were treated with equal elegance and hospitality, to the utter confusion of our aunt, whose prejudices, though beginning to give way, were not yet entirely removed. To-day, by the assistance of our friend, we are settled in convenient lodgings, up four pair of stairs, in the High-street, the fourth story being, in this city, reckoned more genteel than the first. The air is, in all probability, the better; but it requires good lungs to breathe it at this distance above the surface of the earth.--While I do remain above it, whether higher or lower, provided I breathe at all, I shall ever be, Dear Phillips, yours, J.
