Molyneux, who recorded with a good deal of circumstance the influenza of 1693, is the principal authority, along with Dr Walter Harris, of London, for another influenza in 1688, seemingly peculiar to the British Isles. Its effects can be discovered with the utmost certainty in the London bills of mortality for two or three weeks at the end of May and beginning of June, and it is mentioned as “the new distemper” in letters of the time. Is it possible to find an earthquake for it? Webster’s note is: “in the same year with an eruption of Vesuvius, after a severe winter and earthquakes”--which is somewhat general. Turning to Evelyn’s diary, where these matters are often recorded, we find, in the very weeks when the influenza was at a height in London, this entry: “News arrived of the most prodigious earthquake that was almost ever heard of, subverting the city of Lima and country in Peru, with a dreadfull inundation following it”--as if the influenza and the news of the earthquake had reached London at the same time. This was the earthquake of 20th October, 1687, which destroyed Lima, Callao and an immense district along the coast of Peru. The rocking of the earth was most violent, the sea retreated like a sudden immense ebb and filled again like a sudden immense flood, the effect of the commotion being felt on board ships a hundred and fifty leagues out in the Pacific. It was remarked that wheat and barley would not thrive in Peru after that earthquake[775]. Here was undoubtedly a great disturbance of soil and of subsoil, almost certainly attended with the discharge of effluvia or miasmata into the air, as in other great earthquakes. But the universal slight fever of the British Isles in the months of June and July, 1688, is remote from the earthquake of Lima in place; and, if it be a question of earthquakes at all, there are others nearer to it both in place and time, such as that in the Basilicata province of Naples in January, 1688, and the Jamaica earthquake, felt through all the island, on the 1st of March, 1688. The greatest of them all, that of Smyrna, on the 10th of July, was a few weeks too late for the hypothesis.
