 abrupt cliaiige in a northerly direction towards Minanii-i, and crosses 

 the pass of Yenoki-zaka to Kökita as far as the city of Fukiii. in Kclii/en. 

 It will be seen from the map (PI. XXL\). that the neigh])om-ho()d 

 of liikonc at the eastern bcmler of Lake lîiwn, was severelv shaken 

 and deeply damaged by the earth(juake. whereas the stretch of land 

 between tliis .Tnd the ]\[in()-Owari ])lain suffered verv little. Such an 

 abnormal nlienomenon hîid been already noticed bv KliH>-e, l(~)no- a"'o 

 as 1861, when he says : '• dass ein Erdl)C'ben diu'ch seine letzen, abge- 

 schwächten AVellen an einem anderen, weit entfernten Funkte eine 

 selbständige Erschütterung her\'orrufen kann, die möglicherweise einen 

 gana anderen Ursprung hat, a>ls dieses ])rimäre Erdbeben. Es ist dies 

 eine Erscheinung, welcher bis jetzt noch niclit die Ijeachtung gewidmet 

 woi'den ist, welche sie verdient. Es giebt nämlich Stossgebiete, welche 

 gewissermaassen den Wiederhall oder das Echo weit entfernter Erd- 

 beben bilden, in denen zwa.r die Disposition zu einer Erderschutterung 

 vorha.nden ist, diesell)e aber häufig erst, Avie es scheint, duix-h eine 

 andere geweckt werden muss."* A. \. T/isaulx** named such a.n earth- 

 quake the sympathetic, or Jlclaisiu'lirn. The destructive shocks near 

 Hikone, esneciadlv Xa^'ahama. p,t tlie time of the «Treat convulsion 

 in tlie neighbouring provinces, seem to me to have been caused by 

 the above-mentioned secondary earth(|uakes or Rclai^Jx'Jx'u. Tt must, 

 however, be remarked that the intc^nsity of shocks felt on tlie surface has 

 greatly to do with the oroiimpliic condition (^f the region concerned. 

 besides the reason given l)y v. Lasaulx.
