[768] Holm, Vom Erdbrande auf Island im Jahre 1783, Kopenhagen, 1784, says: “Since the outbreak began, the atmosphere of the whole country has been full of vapour, smoke and dust, so much so that the sun looked brownish-red, and the fishermen could not find the banks.... Old people, especially those with weak chests, suffered much from the smell of sulphur and the volcanic vapours, being afflicted with dyspnoea. Various persons in good health fell ill, and more would have suffered had not the air been cooled and refreshed from time to time by rains,” pp. 57, 60. The real sickness of Iceland in those years had been before the volcanic eruptions, in 1781 and 1782, when some parts of the island were almost depopulated by the famine and pestilential fevers that followed the unusual seasons.

[772] A few cases have been exceptionally seen at Spanish Town, six miles from the head of the bay, the infection of which was supposed to have been brought from the shore by sailors, and it has also prevailed in the barracks on the high ground of Newcastle not far from the shore.
[773] Without seeking to argue for the connexion between particular earthquakes and influenzas, but merely to illustrate the possibilities, I append here an instance that ought not to be overlooked. On the 1st of November, 1835, there was a great earthquake in the Moluccas, which so completely changed the soil of the island of Amboina, that it became notably subject to deadly miasmatic or malarious fevers from that time forth. For three weeks before the earthquake the atmosphere had been full of a heavy sulphurous fog, so that miasmata were rising from the soil by some unwonted pressure before the actual cataclysm. There is no doubt at all that Amboina became “malarious” in a most marked degree from the date of the earthquake; it is a classical instance of the sudden effect of great changes in the earth’s crust upon the frequency and malignity of remittent and intermittent fevers, according to the testimony of physicians in the Dutch East Indian service. The influenza nearest to the earthquake was about a year after, at Sydney, Cape Town, and in the East Indies, during October and November, 1836. The epidemic appeared about the same time in the north-east of Europe, spread all over the continent, and reached London in January, 1837. There was again influenza in Australia and New Zealand in November, 1838, two years after the last outbreak in that region.
