"It is to be noted that, from our point of view, only the great 

 oscillation from east to west (which was the most measured and free 

 from violent shocks), indicates the true inclination of the buildings 

 towards the west. 



" 1. The greatest oscillation from E. 5° S. to W. 5° W. ; the ampli- 

 tude of the greatest oscillation 22°, or by seismic wave motion 11° to 

 east and 11° to west. 



" 2. Greatest oscillation from south-west to north-east, true, ampli- 

 tude 19°, but with the difference of more inclination towards the 

 south-west, which reached to 10° 10', against 8° 50' only towards the 

 north-east. 



" 3rd. Greatest oscillation from 1ST. 4° W". to S. 4° E., amplitude of 

 this oscillation 16°, in which also is observed that the inclination is 

 greater towards the south, being 9° south and only 7° north, the impulse 

 consequently appears to be from north to south. 



" The index of the vertical seismometer departed 34 millims. from 

 its position. Erom the time of this earthquake until the 20th at three 

 in the afternoon, at which time we experienced a very strong repetition, 

 an uninterrupted series of small shocks were felt, which indicated that
