Sculpture and painting are arts which, one would imagine, are of very difficult and almost impracticable attainment to blind persons ; and yet instances occur, which show, that they are not excluded from the pleasing, creative, and extensive regions of fancy.

De Piles mentions a blind sculptor, who thus took the likeness of the Duke de Bracciano in a dark cellar, and made a marble statue of King Charles I. with great justness and elegance. However unaccountable it may appear to the abstract philosopher, yet nothing is more certain in fact, than that a blind man may, by the inspiration of the Muses, or rather by the efforts of a cultivated genius, exhibit in poetry the most natural images and animated descriptions even of visible objects, without deservedly incurring the charge of plagiarism. We need not recur to Homer and Milton for attestations to this fact; they had probably been long acquainted with the visible world before they had lost their sight, and their descriptions might be animated with all the rapture and enthusiasm which originally fired their bosoms, when the grand and delightful objects delineated by them were immediately beheld. We are furnished with instances in which a similar energy and transport of description, at least in a very considerable degree, have been exhibited by those on whose minds visible objects were never impressed, or have been entirely obliterated.

Dr. Blacklock affords a surprising instance of this kind ; who, though he had lost his sight before he was six months old, not only made himself master of various languages, Greek, Latin, Italian, and French; but acquired the reputation of an excellent poet, whose performances abound with appropriate images and animated descriptions.

Dr. Nicholas Bacon, a blind gentleman, descended from the same family with the celebrated Lord Verulam, was, in the city of Brussels, with high approbation created LL. D. He was deprived of sight at nine years of age by an arrow from a cross-bow, whilst he was attempting to shoot it. When he had recovered his health, which had suffered by the shock, he pursued the same plan of education in which he had been engaged; and having heard that one Nicasius de Vourde, born blind, who lived towards the end of the fifteenth century, after having distinguished himself by his studies in the university of Louvain, took his degree as D. D. in that of Cologne, he resolved to make the same attempt. After continuing his studies in learning philosophy and law a sufficient time, he took his degree, commenced pleading as counsellor or advocate in the council of Brabant, and has had the pleasure of terminating almost every suit in which he has been engaged to the satisfaction of his clients.

Another instance, which deserves being recorded, is that of Dr. Henry Moyes, in our own country ; who, though blind from his infancy, by the ardour and assiduity of his application, and by the energy of native genius, not only made in-credible advances in mechanical operations, in music, and in the languages; but acquired an extensive acquaintance with geometry, optics, algebra, astronomy, chemistry, and all other branches of natural philosophy.

From the account of Dr. Moyes, who occasionally read lectures on philosophical chemistry at Manchester, delivered to the Manchester Society by Dr. Bew, it appears, that mechanical exercises were the favourite employment of his infant years : and that at a very early age he was so well acquainted with the use of edge-tools, as to be able to construct little windmills, and even a loom. By the sound, and the different voices of the persons that were present, he was directed in his judgment of the dimensions of the room in which they were assembled; and in this respect he determined with such a degree of accuracy, as seldom to be mistaken. His memory was singularly retentive; so that he was capable of recognizing a person on his first speaking, though he had not been in company with him for two years. He determined with surprising exactness the stature of those with whom he conversed, by the direction of their voices; and he made tolerable conjectures concerning their dispositions, by the manner in which they conducted their conversation. His eyes, though he never recollected having seen, were not totally insensible to intense light: but the rays refracted through a prism, when sufficiently vivid, produced distinguishable effects upon them. The red produced a disagreeable sensation, which he compared to the touch of a saw. As the colours declined in violence, the harshness lessened, until the green afforded a sensation that was highly pleasing to him, and which he described as conveying an idea similar to that which he gained by running his hand over smooth polished surfaces. Such surfaces, meandering streams, and gentle declivities, were the figures by which he expressed his ideas of beauty; rugged rocks, irregular points, and boisterous elements, furnished him with expressions for terror and disgust.

He excelled in the charms of conversation ; was happy in his allusions to visual objects, and discoursed on the nature, composition, and beauty of colours, with pertinence and precision.

This instance, and some others which have occurred, seem to furnish a presumption, that the feeling or touch of blind persons may be so improved as to enable them to perceive that texture and disposition of coloured surfaces by which some rays of light are reflected, and others absorbed ; and in this manner to distinguish colours

In music, there are at present living instances of how far the blind may proceed. In former periods we shall find illustrious examples, how amply nature has capacitated the blind to excel, both in the scientific and practical departments of music.

In the sixteenth century, when the progress of improve ment both in melody and harmony was rapid and conspicuous, Francis Salinas was eminently distinguished. He was born A. D. 1513, at Burgos in Spain; and was son to the treasurer of that city. Though afflicted with incurable blindness, he was profoundly skilled both in the theory and practice of music. As a performer, he is celebrated by his contemporaries with the highest encomiums. As a theorist, Sir John Hawkins says, his book is equal in value to any now extant in any language. Though he was deprived of sight in his earliest infancy, he did not content himself to delineate the various phenomena in music, but the principles from whence they result, the relations of sound, the nature of arithmetical, geometrical, and harmonical ratios, which were then esteemed essential to the theory of music, with a degree of intelligence which would have deserved admiration, though he had been in full possession of every sense requisite for these disquisitions. He was taken to Rome in the retinue of Petrus Sarmentus, archbishop of Compostella, and having passed twenty years in Italy, he returned to Salamanca, where he obtained the professorship of music, an office at that time equally respectable and lucrative. Having discharged it with reputation and success for some time, he died at the venerable age of seventy-seven.
