208 REPORT—1899. 
The fact that the large waves reached Trieste, Rocca di Papa, and 
Nicolaiew at about the same time, and the English stations 10 minutes 
later, also indicate that the origin of this shock was in Greece.

At Shide the early part of the disturbance is eclipsed by air tremors. 
The first echo, the amplitude of which is equal to that of the maximum 
at Oh. 34m., was at Oh. 37m. The Kew record is distinctly smaller than 
the one from Shide, the amplitudes at these places being 4 mm. and 
6 mm. respectively. 
The following notes throw light upon the nature of the shock near to 
its origin, and other disturbances, with which it has been confused. 
The Sub-Director of the Central Meteorological and Magnetic 
Observatory in Mexico, Senor José Zandejas, writes to Professor R. F. 
Stupart of Toronto, as follows :— 
‘ Owing to the temporary absence of Senor Barcena, I have great pleasure 
in answering your favour of January 26 last, and inform you that the 
shock of earthquake on the 24th of the same month was felt here at 
5h. 23m. (local time) and lasted 2 minutes, causing some damage to 
old buildings, but cannot be classified as very strong. Generally they are 
not in the capital. It was felt from Vera Cruz on the east to St. Blas 
on the west, both seaports, one in the Gulf and the other on the Pacific, 
declining towards the south to the Pacific Ocean and Tehuantepec 
Isthmus, including the States of Jalisco, Colima, Michoacan, Guerrero, 
Pueblas, Flaxcala, Mexico, Oaxaca, and Vera Cruz, which is the territory 
where earthquakes are generally felt and in which the volcanos of the 
Republic are situated. 
‘ As these phenomena have not been sufficiently studied, it would be 
hazardous to point out a determinate point of convergence of their 
probable origin, but it has been noticed that the greatest intensity and 
frequency of these earthquakes take place in the States of Michoacan, 
Guerrero, Oaxaca, and Chiapas to Guatemala, (c., and might extend with 
still greater violence to the Pacific Ocean.’ 
In a subsequent letter Senor Zandejas corrects the above time to 
January 24, 5.29 am. and adds that there was a second shock at 
5.9 p.m. (mean local Mexican time). The former was slight and the latter 
was strong.
