On Lunar Periodicities in Earthquakes, 



Over and above tlie regular vocabulary of Glas, isolated words 

 (such as the name of the various kinds of fish) are to be found 

 in his work. The numerals, moreover, and a few other words, 

 occur, from other miscellaneous sources, in the paper of the 

 Geographical Transactions. 



On Lunar l-'eriodicities in Earthquakes, and remarkable At- 

 mospherical Fhenomena, By RiCHAKD EDMONDS jun., Esq. 

 Communicated by the Author. 



In a paper, of which an abstract appeared in the Number of this 

 Journal for April (p. 271), I have noticed some very striking instances 

 of lunar periodicities in earthquakes, extraordinary oscillations of the 

 sea, and great atmospherical changes. The last few months have 

 furnished me with additional examples. The remarkable maxima of 

 the barometer which are noticed in the following table, occurred at 

 successive intervals of single lunations — the principal ones being on 

 the 21st of December and the 21st of March : —

 (Cornwall, published in the West Briton. 



t Almost exactly four lunations after this shock at Alexandria, when 

 the English ship Victory was in the Mediterranean, in lat. 36" 40', long. 

 13" 44', " her top-gallant masts and royal mast went suddenly over the 

 side, as if by a sudden heavy squall, though there was not at the time 

 the least appearance of a squall." Two hours afterwards three immense 

 balls of fire rose from the sea, and remained visible for about ten minutes. 

 This happened on the evening of the 18th of June. On the same even- 

 ing, from Mount Lebanon were seen, for an hour, two very bright me- 

 teors moving towards the east, and connected with each other by streams 

 of light — each meteor being apparently five times larger than the full 

 moon, which had just risen.
