to send me the following interesting note on Jade: "Jade and Jadeite, the appearance of which is perfectly similar, may, according to the latest investigations by A. Arzruni[1] and by Berwerth,[2] be easily distinguished, because Jade belongs to the group of the Amphibols, Jadeite to the group of Pyroxen-minerals, and consequently they differ considerably in the size of the angles of cleavage in which the finer fibres may be recognised."
There were also found two of those curious instruments of diorite (like that represented in Ilios, p. 243, No. 90), which have the same shape as the axes, with the sole difference that at the lower end, where the edge ought to be, they are blunt, perfectly smooth, and from a quarter to half an inch thick. Two precisely similar implements, found in caverns of the stone period in Andalusia, are in the Prehistoric Museum at Madrid; another, discovered in the cavern called "Caverna delle Arene," near Genoa, is in the Prehistoric collection of the Museo Nazionale in the Collegio Romano at Rome.
There were also found four whetstones of indurated slate, with a perforation at the smaller end, like that represented in Ilios, p. 248, No. 101. Besides the places enumerated in Ilios (p. 248), at which similar whetstones were found, I may mention that one, discovered in a tomb at Camirus in the island of Rhodes, is in the Louvre, and three, found in Swiss lake dwellings, are in the Museum of Geneva; another whetstone, of an identical form, was found in the prehistoric cemetery of Koban in the Caucasus.[3]
No. 11 represents a battle-axe of grey diorite; it is of rude manufacture, and but little polished. It has only one
