In a medical point of view, the water of Matlock may be employed in all those cases in which a pure diluent drink is advisable; but it is chiefly used as a tepid bath--or at least as one which exceeds the extreme limits of a cold bath. On this account, it produces only a slight shock on immersion, and is, therefore, peculiarly fitted for those delicate and languid habits that cannot exert sufficient reaction to overcome the effects of the common cold-bath, and on which the benefit it produces chiefly depends. It forms a good intermediate bath between that of Bath or Buxton and the sea, and may be recommended as a preparative for the latter. The abundant supply of water always at the same temperature is a circumstance in favour of natural baths; while the purity of the air and exquisite beauty of the situation must always render Matlock a favourite resort for the invalid and man of taste. To the geologist it presents a wide and interesting field of observation. Few districts in England comprise within the same limits so great a proportion of poetical and historical scenes. [Illustration: CONWAY CASTLE.] CONWAY CASTLE, NORTH WALES. "Tantôt c'est un vieux fort, qui, du haut des collines, Tyran de la contrie, effrei de ses vassaux, Portait jusqu'au ciel l'orgueil de ses crénaux; Qui, dans ces temps affreux de discorde et d'alarmes, Vit les grands coups de lance et les noble faits d'armes De nos preux chevaliers...... Aujourd'hui la moisson flotte sur ses débris." Conway, or more properly Aberconway--so called from its position on the river of that name--makes no inconsiderable figure in the page of ancient history. It appears, on the testimony of Suetonius, the Roman governor in Britain, that the chief motive entertained by his countrymen in their occupation of this coast was a pearl fishery at the mouth of the river Conway; a specimen of which, presented by Sir R. Wynne to the Queen of Charles the Second, is said to have found a place among the jewels that now adorn the British diadem. The town of Conway is large, though not populous, and in situation and appearance highly picturesque. It is surrounded by lofty embattled walls, a mile and a half in circumference, well preserved, defended by twenty-four round-towers and four gates, and presenting at all points a striking picture of the ancient style of fortification. From the side towards the river ran two curtain-walls, terminating in watch-towers, but of which only one remains. The castle, a truly grand and imposing structure, was built in 1284; an epoch which gave origin to so many of those native fortresses, which will long continue to be the subject of interest and admiration to every traveller in this romantic country.
