PREFACE.
Of the approach of a disorder there are many signs. In the explication of which, I shall, without hesitation, make use of the authority of the ancients, and more especially that of Hippocrates; as even the more modern physicians, although they have made alterations in the method of curing, nevertheless confess, that he has delivered the best prognostics from these signs. But before I speak of those antecedents, which give cause to apprehend distempers ensuing; it seems not improper to explain, what seasons of the year, what kinds of weather, what times of life, what constitutions are most safe from, or most obnoxious to dangers, and what kinds of disorders are most to be feared in each of these. Not but in any weather(1), men of all ages and all habits, fall into all kinds of distempers, and die of them too; but because some events are more frequent than others. And therefore it is useful for every person to know, against what, and when, he should be most upon his guard.
