Likewise in the year 1670.
Again in the year 1677.
Again very mortal in the year 1684.
* Out of the register-book.
Mr. Ax also promised me to enquire at Taunton the years it happened
there after 1660.
It were to be wished that more such observations were made in other
great towns.
Platerus makes the like observations in the second book of his
Practice, p. 323. He practised at Basil, fifty six years, and did
observe, that every tenth year they died of the plague there.
See Captain J. Graunt's observations on the bills of mortality at
London, (indeed written by Sir William Petty, which in a late
transaction he confessed) for the periodical plagues at London, which
(as I remember) are every twenty-fifth year.
