consequence of this oscillation between the two planes mentioned, 

 the crystal appears to be made up of a lot of lozenge-shaped 

 plates piled one upon another, with the smallest forming the 

 dodecahedral bounding plane of the crystals, and the edges of 

 the pile the deeply striated icositetrahedral faces. In small frag- 

 ments the mineral is transparent and has the usual deep red color 

 of almandine. Its exact method of occurrence is unknown.

1. The Great Earthquake of Japan, 1891; by Prof. John 

 Milne, F.R.S., and Prof. W. K. Burton, C.E., with plates by 

 K. Ogawa. Yokohama, 1892. — On the morning of October 28, 

 1891, there occurred in Japan an earthquake, which, even in that 

 much shaken country, is already known as " the Great Earth- 

 quake." Its greatest force was exerted in the neighborhood of 

 Gifu and Nagoya, towns some fifteen miles west of Tokyo, but it 

 was felt from Sendai on the north to Nagasaki on the south over 

 an area of 92,000 square miles, and the area of complete destruc- 

 tion of buildings was 4200 square miles. The first and most 

 severe shock occurred at Gifu at 6 h 38 m 11 s on the morning of 

 October 28, and was followed by numerous minor shocks to the 

 number of several thousand in the twelve days next following. 

 One authority stated the number of persons killed in the prefec- 

 tures of Aichi and Gifu at 7528, the wounded 9458, houses totally 

 destroyed 82,000, partially destroyed 23,000, damage to property 

 120,000,000. A recent letter from Prof. Milne, puts the dead at 

 10,000 and the loss at $50,000,000. 



It is this great earthquake which is illustrated in the series of 

 plates whose title is given above and which forms an oblong 

 quarto volume 29 cni X 41 cm in size. The plates are heliotype 

 copies of photographs, all but three of which were made by the 

 authors for the Imperial University of Japan, and are copy- 

 righted in its name. It is published by Lane Crawford & Co., 

 Yokohama. The press work w T as done in Tokyo, and the paper 

 on which it is printed is a product of the very district shaken 

 by the earthquake. Indeed there was some delay in printing 

 proofs owing to the difficulty of getting the paper in the dis- 

 organized state of all manufactures. It is handsomely bound in 

 cloth and in general make up the book will compare favorably 

 with the product of any western press. The first edition of 1000 

 copies has all been sold and a second edition with a few additional 

 plates is in preparation.
