That the written Abyssinian language, which we call Ethiopick, is a dialect of old Chaldean, and sister of Arabick and Hebrew; we know with certainty, not only from the great multitude of identical words, but (which is a far stronger proof) from the similar grammatical arrangement of the several idioms:  we know at the same time, that it is written like all the Indian characters, from the left hand to the right, and that the vowels are annexed, as in Devanagari, to the consonants; with which they form a syllabick system extremely clear and convenient, but disposed in a less artificial order than the system of letters now exhibited in the Sanscrit grammars; whence it may justly be inferred, that the order contrived by PANINI or his disciples is comparatively modern; and I have no doubt, from a cursory examination of many old inscriptions on pillars and in caves, which have obligingly been sent to me from all parts of India, that the Nagari and Ethiopean letters had at first a similar form.  It has long been my opinion, that the Abyssinians of the Arabian stock, having no symbols of their own to represent articulate sounds, borrowed those of the black pagans, whom the Greeks call Troglodytes, from their primeval habitations in natural caverns, or in mountains excavated by their own labour:  they were probably the first inhabitants of Africa, where they became in time the builders of magnificent cities, the founders of seminaries for the advancement of science and philosophy, and the inventors (if they were not rather the importers) of symbolical characters.  I believe on the whole, that the Ethiops of Meroe were the same people with the first Egyptians, and consequently, as it might easily be shown, with the original Hindus.  To the ardent and intrepid MR. BRUCE, whose travels are to my taste, uniformally agreeable and satisfactory, though he thinks very differently from me on the language and genius of the Arabs, we are indebted for more important, and, I believe, more accurate information concerning the nations established near the Nile, from its fountains to its mouths, than all Europe united could before have supplied; but, since he has not been at the pains to compare the seven languages, of which he has exhibited a specimen, and since I have not leisure to make the comparison, I must be satisfied with observing, on his authority, that the dialects of the Gafots and the Gallas, the Agows of both races, and the Falashas, who must originally have used a Chaldean idiom, were never preserved in writing, and the Amharick only in modern times:  they must, therefore, have been for ages in fluctuation, and can lead, perhaps, to no certain conclusion as to the origin of the several tribes who anciently spoke them.  It is very remarkable, as MR. BRUCE and MR. BRYAN have proved, that the Greeks
