[27] Brownrigg cites the Leyden epidemic of 1669, which he calls an intermitting fever, as an instance of the effects of changes in the ground water; it was “powerfully aggravated by the mixture of salt water with the stagnant water of the canals and ditches. This fever happened in the month of August, 1669, and continued to the end of January, 1670.” “Observations on the Means of Preventing Epidemic Fevers.” Printed in the Literary Life of W. Brownrigg, M.D., F.R.S. By Joshua Dixon, Whitehaven, 1801.

[35] In the Belvoir Letters (Hist. MSS. Com. Calendar) Charles Bertie writes from London to the Countess of Rutland, 26 January, 1685, that “many are sick of pestilential fevers.” Evelyn says that the winter of 1685-6 was extraordinarily wet and mild, but does not mention sickness until June, 1686, when the weather was hot and the camp at Hounslow Heath was broken up owing to sickness.
