Loth practical and tlieorctical. Omori's results on tlie production of 

 the vibrations of chimneys transverse to the wind has been discussed 

 niatheniatically by Nagaoka/^^ by an analogy of the eolian harp. 



As an ai)plication of seisniometry, the vibrations of railway 

 trains, and also of different railroad constructions such as bridges and 

 piers, have been extensively studied by Omori/^^ 



Damage to water conduits and the like caused by earthquakes 

 has also been the subjects of investigations by Omori, Tanabe and 

 others. Besides, the strengths of various building materials have been 

 extensively investigated. 



To our regret, it seems well nigh impossible to refer even to the 

 most important of all these useful and interesting investigations, 

 w'ithout making present note unduly lengthy and voluminous. 



Lastly, we must spend a few words on the investigation by the 

 E.I.C. of the great conflagration which eusued after the late great 

 earthquake and caused a vast loss of lives and property, far surpassing 

 in degree what might have been expected as the mere result of the 

 earthquake. The results of investigations from various sides, physical, 

 chemical, meteorological, as well as administrational, are compiled as 

 Ho., No. 100 E,*^"'- the reports being contributed by different membets 

 of the Conmiittee, sonje of them being specially appointed on this 

 occasion. It must be added here that the conflagration was clearly 

 foreseen by Oniori and Imamnra who took every . opj)ortunity to warn 

 the government as. well as the inhabitants of the City of Tokyo wisely 

 to provide beforehand for the terrible calanjity to come sooner or later. 

 On reading their writings concerning this matter after the recent 

 disaster, we cannot but regret universal apathy of the general public 

 in listening to the well-founded warnings of scientists. 



Geological Investigations 



We cannot conclude this brief sketch on the development of 

 seismology in our country without saying a few words on the valuable
