The Composition of Meteoric Stones. Dr. F. Grace Calvert in one of his Cantor lectures makes the following statements in regard to the composition of meteoric stones which are so fre quently falling upon this earth from the unknown regains of space. Notwithstanding the careful analyses that have been made of these meteoric stones the presence of no new metal has been discovered in them or of any which chemists have not found upon our own planet; but they have been able to ascertain that some of these aerolites contain or are composed in some instances of metals in a native state which are It has been proved that some of them contain me tallic nickel cobalt and even iron; in fact in some instances the volume ot some of these aerolites that have fallen on our planet which are composed of iron has been sufficient to allow man to work them directly into implements. Such was the case with an aerolite found in Mexic which had the follow ing compositions: Iron 96.50; nickel 3.50; total 100 What in a scientific point of view enhances the value of this peculiar class of meteoric Stones is the presense in some of them of a peculiar yellow mineral having a great resemblance to pyrites but still differing entirely from it in composition as proved by the analysis of Mr. Lawrence Smyth who found it to be composed of tour equivalents of iron two equivalents of nickel and one equivalent of phosphorus and to it he gave the name of ' Schrei bersite.' It has lately been artificially produced by Mr. Faye under the able guidance of Henry St. Claire Deville by melting together in a crucible a mixture of oxides of iron and nickel phosphate of soda silicS and charcoal allowing the whole to cool when in the fused-mass were found well defined crystals having a yellow color and identical in com position to the ' schreibersite ' analyzed by Mr. Lawrence Smyth—a triumph of science for it is the large proportion of metallic iron and especially of phosphorus in this class of aerolites proves t
