The successive discoveries since the third of last January at nearly the same place, and at a depth of from 3 to 6 meters beneath the surface, of numerous _Inculi_ absolutely identical as to material and structure with those of which we have just spoken, is therefore a scientific event of high importance. Those discoveries, which were purely accidental, were brought about by the work on the foundations of the Maritime Arsenal now in course of construction at the gates of Cadiz. Our Fig. 1 represents the unearthing of the _loculi_ on the 14th of April, and on the value of which there is no need to dwell. As to the dimensions, it is easy to judge of these, since the laborer standing to the left of the spectator holds in his hand a meter measure serving as a scale. It will suffice to state that the depth of each tomb is about two meters, and that upon the lower part of three of the parallelopipeds there exist pavements of crucial appearance. Finally, nothing denoted externally the existence of these sarcophagi jealously hidden from investigation according to a usage that is established especially by the imprecations graven upon the basaltic casket now preserved in the Museum of the Louvre, and which contained the ashes of Eshmanazar, King of Sidon. [Illustration: ANTHROPOID SARCOPHAGUS DISCOVERED AT CADIZ.] Space is wanting to furnish ampler information. Our object is simply to call attention to a zone which is somewhat neglected from a scientific point of view, and which, however, seems as if it ought to offer a valuable field of investigation to students of things Semitic, among whom, as well known, our compatriots hold a rank apart, since it is to them that falls the laborious and very honorable duty of collecting and editing the inscriptions in Semitic languages. On another hand, although in the beginning the sepulchers were taken to pieces and carried away (two of them imperfectly reconstructed may be seen in the garden of the Cadizian Museum), there will be an opportunity of making prevail the system of maintaining _in situ_ the various monuments that may hereafter be discovered. Thus only could one, at a given moment, obtain an accurate idea of what the Phenician necropolis of Cadiz was, and allow the structures that compose it to preserve their imposing stamp of rustic indestructibility. The excavation is being carried on at this very moment, and a bronze statuette of an oriental god and various trinkets of more or less value have just enriched the municipal collection. Let us hope, then, as was recently predicted by Mr. Clermont Ganneau, of the Institute, that some day or another some Semitic inscription will throw a last ray of light upon the past, which is at present so imperfectly known, of Phenician Cadiz.--_L'Illustration._ * * * * * PREHISTORIC HORSE IN AMERICA. _To the Editor of the Scientific American_:
