and Extraordinary Movements of the Sea. 279 
Each of the above thirteen days was either that of the 
moon's first quarter, or the day before or after it, except the 
9th of October 1842, which was the second day before it.” 
Heve follow four tables of lunar periodicities, and also 
an account of some earthquakes in Cornwall. The paper 
concludes with the following paragraph :—‘ It has been seen 
that earthquakes, oscillations of the sea, great atmospheri- 
cal changes, and electrical phenomena, are closely connected 
with each ot) er: and I have endeavoured to shew that they 
may all result principally from the action of the moon. In 
support of this hypothesis, I have noticed two oscillations 
of the sea at and after the great earthquake of 1755, and two 
others at and after the great earthquake of 1761, the inter- 
val in each case being four lunations. I have also, in Table 
I., noticed eleven other such intervals,—six following each 
other in one series. and five in another. Each of the thirteen 
days forming these two series was remarkable for an earth- 
quake, oscillation of the sea, or some very unusual state of 
the atmosphere, except on one occasion, when, however, an 
eruption of Vesuvius took place. In the same Table are 
many other similarly remarkable days, forming series of 
periods of single lunations, or of half or quarter lunations. 
All the remarkable days in Tables I. and IV., as well as those 
in the last two pages, connected with the earthquakes in Corn- 
wall, occurred at or near the moon’s quarters, and generally at 
or near her first quarters. But the remarkable days in Tables 
Il. and III. did not happen near any of the four quarters, yet 
are, nevertheless, connected with each other by single luna- 
tions ; so that the phenomena which occurred on these days 
were apparently as much influenced by the action of the moon 
as those which happened at or near her quarters.” 
point, and when placed on snow 44° below that point. This great maxi- 
mum of the barometer, and this most extraordinary minimum of the 
thermometer, occurred on the morning of the 12th, which is almost ex- 
actly four lunations after the great minimum of the barometer at Chis- 
wick, on the 16th of October last.—PmNnzANCE, March 1. 1845.
