SCIENCE. 



[Vol. XXII. No. 545 



jourrnl, ivhioh is therefore to bs regarded, not as an entirely new 

 venture, but as a continuation of the series heretofore known as 

 the Transactions of the Seismologieal Society. The new journal 

 is issued in the same form and from tlie same printers as the old 

 Transactions, and the first number, now at hand, bears on its 

 title page Vol. XVII, which is its number in the old series, so 

 that the new volumes can he bound uniformly with those 

 previously issued. The annual subscription is five dollars. 



In this number the first article is on ' The Mitigation of Earth- 

 quake Effects and Certain Experiments in Earth Physics" by 

 Professor Milne, in which various lines of experiment are pro- 

 posed that might possibly lead to the prediction of severe earth- 

 quakes so as to guard against their effects. In the second, '-On 

 the Application of Photography to Seismology and Volcanic 

 Phenomena," Professor W. K Burton describes with illustrations 

 the photographic records from Milne's t emor indicators. In the 

 third Professor Milne gives an abstract of the " Seismometrical 

 Observations for the Year 1890," from which itappears that in that 

 year 845 earthquakes were felt in Japan, of which 49 were classed 

 as severe, 264 as moderate and 533 as feeble. Of the severe 

 earthquakes, four (Jan. 7, Mar. 19, Apr. 16, Nov 17) were 

 accorded more detailed description. In the fourth article " On 

 the Overturning and Fracturing of Brick and other Columns, 

 by Horizontally Applied Motion," Professor Milne and F. Omori 

 describe a very interesting series of experiments, wherein various 

 objects such as blocks of wood of different dimensions, bricks, 

 columns bjilt of brick or of cement, were mounted on a 

 wheeled truck to which a reciprocating horizontal motion 

 could be communicated, and the circumstances of the motion, with 

 the overturning or fracture of the object, were electrically 

 recorded. From the data the maximum velocity and maximum 

 accelleration necessary for overturning were calculated and 

 compared with the experimental results with a fairly good agree- 

 ment. In an article on "Eirth Pulsations in Regard to Certain 

 Natural Phenomena and Physical Investigations,"' Professor Milne 

 concludes that " the movements called earth tremors are move- 



ments In the crust of the earth not altogether unhke the swell 

 upon the ocean," and infers a connection between them and the 

 steepness of the barometric gradient. In an article ' ' On the Move- 

 ments of Horizontal Pendulums," he gives an abstract with notes 

 of certain observations made by Dr. E. von Rebeur-Paschwitz at 

 Potsdam, Wilhelmshaven and Teneriffe, and published in the 

 Astronomische Nuchrkhten. F. Omori gives "A Note on Old 

 Chinese Earthquakes," and as the concluding article Professor 

 Milne gives a twenty-page "Note on the Great Earthquake of 

 October 28, 1891," the phenomena of which are further discassed 

 in his report to the British Association, 1892, and the complete 

 account of which is to be issued under the auspices of the 

 Imperial University of Japan, but is not yet ready for publica- 

 tion. According to the statements of this account the killed 

 numbered 9,960, wounded 19,994, and houses totally destroyed 

 138,750. The immediate cause of the disaster was the formation 

 of a fault which can be traced on the surface of the earth for a 

 distance of between forty and fifty miles, and shows a difference 

 of level amounting in many places to twenty or thirty feet. 

 There is also abundant evidence of horizontal displacements, 

 sometimes as great as eighteen feet, and the whole Neo Valley 

 appears to have suffered a permanent compression, becoming 

 narrower, the piers of bridges being left closer together than 

 before the earthquake. There were also many observations of 

 surface waves in the earth, involving a perceptible tilting of 

 objecls renting upon it ; and the maximum horizontal motion 

 indicated by the instruments was from 25 mm to 35 ram. with 

 a period of from 1 to 2.5 seconds.

THE MODERN MALADY ; or, Suf- 

 ferers from ' Nerves.' 



Au introduction to public consideration, 

 from a non-medical point of view, of a con- 

 dition of ill-health which is increasingly 

 prevalent in all ranks of society. In the 

 firsfpart of this work the author dwells on 

 the errors in oui- mode of treating Neuras- 

 thenia, consequent on the wide ignorance of 

 the subject which still prevails; in the sec- 

 ond part, attention is drawn to the principal 

 causes of the malady. The allegory forming 

 the Introduction to Part I. gives a brief his- 

 tory of nervous exhaustion and the modes of 

 treatment which have at various times been 

 thought-Suitable to this most painful and try- 

 ing disease.
