The Earthquake Catalogue of the British Association, First one-volume edition of this foundation work of seismology, "the first really scientific investigation" on the topic (Davison, p. 81); inscribed from the author to William Cole, 3rd Earl of Enniskillen, an Irish palaeontologist who worked closely with Mallet. The inscription on the title page reads "To the Earl of Enniskillen with the author's respects".The Irish civil engineer and scientist Robert Mallet (1810-1881) is often referred to as the father of seismology, not least for having coined the word, alongside other key terminology like epicentre, seismic focus, angle of emergence, isoseismal line, and meizoseismal area. At the beginning of his earthquake studies "[Mallet] produced an experimental seismograph in 1846. Important elements of his model, which was never actually used, were incorporated in the seismograph that Luigi Palmieri made in 1855. Between 1850 and 1861 Mallet set off explosions in different locations to determine the rate of travel of seismic waves in sand (825 feet per second), solid granite (1,665 feet per second) and quartzite (1,162 feet per second)... Mallet presented his most important seismic results in four Report[s] to the British Association (1850, 1851, 1852-54, 1858)", the organisation which funded the majority of his research (DSB).
