[622] Since the publication of the first edition of this work,
numerous accounts of recent earthquakes have been published;
but as they do not illustrate any new principle, I cannot
insert them, as they would enlarge too much the size of my
work. The late Von Hoff published from time to time, in
Poggendorf's Annalen, lists of earthquakes which happened
between 1821 and 1836; and, by consulting these, the reader
will perceive that every month is signalized by one or many
convulsions in some part of the globe. See also Mallet's
Dynamics of Earthquakes, Trans. Roy. Irish Acad. 1846; and
"Earthquakes," Admiralty Manual, 1849; also Hopkins' Report,
