A portion of these manuscripts deals with medical and metaphysical subjects, the two being often combined. We are hardly prepared to learn to how great an extent these subjects were studied at an early period in the Highlands. We are apt to think that the region was a barbarous one without either art or science. A sight of the sculptures which distinguished the 14th and 15th centuries is prone to remove this impression. We find a style of sculpture still remaining in ancient crosses and gravestones that is characteristic of the Highlands; elaborate ornaments of a distinct character, rich and well executed tracery, figures well designed and finished. Such sculptures, following upon those of the prehistoric period found still within the ancient Pictish territory, exist chiefly throughout the West Highlands, and indicate that one art, at least, of native growth, distinguished the Gaelic Celts of the Middle Ages. The medical manuscripts existing are chiefly the productions of the famous Macbeths or Beatons, the hereditary physicians of the Lords of the Isles for a long series of years. The charter of lands in Islay, already referred to, drawn out by Fergus Beaton, is of a date as early as 1408, and three hundred years after, men of the same race are found occupying the same position. Hereditary physicians might seem to offer but poor prospects to their patients, and that especially at a time when schools of medicine were almost if not altogether unknown in the country; but the fact is, that this was the only mode in which medical knowledge could be maintained at all. If such knowledge were not transmitted from father to son, the probability was that it would perish, just as was the case with the genealogical knowledge of the _seanachies_. This transmission, however, was provided for in the Celtic system, and while there was no doubt a considerable difference between individuals in the succession in point of mental endowments, they would all possess a certain measure of skill and acquirement as the result of family experience. These men were students of their science as it existed at the time. The Moors were then the chief writers on medicine. Averroes and Avicenna were men whose names were distinguished, and whose works, although little known now, extended to folios. Along with their real and substantial scientific acquirements, they dived deep into the secrets of Astrology, and our Celtic students, while ready disciples of them in the former study, followed them most faithfully and zealously in the latter likewise. There are numerous medical and astrological treatises still existing written in the Gaelic language, and taken chiefly from the works of Moorish and Arabian writers. How these works reached the Scottish Highlands it is hard to say, nor is it easier to understand how the ingredients of the medical prescriptions of these practitioners could be obtained in a region so inaccessible at the time. The following specimen of the
