C. G. Rockwood—Notes on Earthquakes. 291 
Those of San Salvador in January and February, in Cuba, 
Florida and Mexico in the latter part of January, and the 
destructive shocks in the Philippines in July, have already 
been mentioned in this Journal. 
Ou November 9, the city of Agram, after numerous less 
important shakings during the summer, was affected by a vio- 
lent earthquake, which extended over Croatia, Montenegro, 
and a great part of Hungary and Bosnia, and even to Bohemia 
and upper Italy. This, the most severe shock, was followed 
by numerous others in gradually decreasing intensity, so that 
up to the 18th December, 61 distinct shocks had been observed 
in the city, with minor vibrations innumerable. The city 
appears to have suffered frequently in the past, as a list is 
given of 33 earthquakes which have occurred there since 1502. 
The author remarks on the continuance of the subterranean 
noises when the shocks had ceased and the ground was at rest. 
The phenomena still continued at the end of the year. 
On July 4 all Switzerland was shaken by an earthquake, 
which had its origin in the neighborhood of the Simplon. 
myrna and its vicinity suffered on the 22d of:June, and 
again on the 29th of July, when the shocks extended to the 
neighboring islands and did much damage. In Smyrna itself 
one hundred houses were overthrown and thirty persons were 
illed. The centre of disturbance was in the mountains north- 
east of the city, where the village of Menemen was left unin- 
habitable. his earthquake has been described in the French 
scientific journals, This same region has again been shaken 
by the Scio earthquake of 1881, as mentioned above. 
On September 2d an earthquake at Kalavrita, in the Pelo- 
ponnesus, was felt also on the other side of the Mediterranean 
at Tripoli, in Africa. 
r. Fuchs records some observations on the slight vibrations 
which Prof. Perrey has reported as occurring frequently in 
Nice. They are only perceptible at night when all is still, and 
he is inclined to refer them to the dashing of the waves upon 
the shore, although he states that the intensity of the vibration 
does not correspond to that of the wave action, nor yet do the 
Intervals between the vibrations correspond to the intervals 
etween the waves. He suggests that the direction in which 
the waves strike may have influence on the phenomena.
