S. side, the shock was feebly felt, but glasses in a delicate position did notfall, nor was any damage done.

A little beyond this, and higher up the side of the old cone of Rotaro,is a place called Cercola, which showed a few and irregular cracks in theplastering, which may have existed before.

I may here mention that as soon as the people of the injured districtheard of the distribution of money for repairing damages, they devoted theirtime to hunt up every crack in the walls and make much of it. In manycases they believed they had discovered new ones, whereas their attentionwas only now directed to those already existing.

After passing a turning hack to the right, and-on the slope of Montagnone,only faint lateral movement was felt.

4. At the four crossroads a lateral E. and W. movement was observed.There was a faint crack that has a suspicion of being old.

At the village of Bagno no damage was done. In a conversation withthe Chemist and others, I gathered that a faint subsultory, followed by amore distinct lateral, movement in an E. and W. direction was felt. Theshock of the following Wednesday was felt and described as a rumble. Atthe new thermo-mineral water establishment I got, at the source of the water,a temperature of 49° C.

In the city of Ischia (as far as my memory goes) about one half of those-asked replied that they had felt the earthquake. It was generally describedas undulatory. The movement was accompanied by a noise like the rumblingof carriages. There were only a few cracks to be seen, most of which areold ones slightly opened.

Taking the road that leads to Campagnano , after a quarter of an hourswalk, we arrive at a branch road, and close by are some houses markedon the map by the name Capella , where nothing whatever was felt. At ahouse some distance beyond, on the opposite side of the way, there are a few(suspiciously old) cracks. From here to a place called Vico, out of manypeople asked, only a few re]died that they felt the shock faintly.

The village of Campagnano is situated on the crest of a ridge whoseline of axis, if continued, would pass through Casamicciola , and thereforea vibration travelling along it parallel to its axis, we should expect to he feltbut feebly; which was in fact the case. Beyond the church a group of housesknown as Gradonc, stands on the spur near, at right angles to the first; andtherefore, from their position, at the end of a short pendulum, they would beexpected to feel the shock distinctly, which was the case with the first, aswell as with that of the following Wednesday. One woman fell down. A priestdescribed the movement as lateral.

Commencing the return part of the loop-like journey by taking the roadto the hamlet of S. Antonio , where I heard that a faint lateral movementhad been felt, but farther on, close to where the aqueduct crosses the valley,all the inhabitants said they felt the first shock and that of Wednesday very
