2. Secondly I answer; Although this observation of the dog-dayes might perhaps be of some moment in hotter countries, as Greece, where Hippocrates lived, who first made mention of those dales: Yet in colder climates, as England, and such like Countries, they are of little or small force at all, and almost not to be regarded any whit, either in using mild & temperate purgatives, or almost in any other; or in blood-letting: though very many, or most doe erroniously say and thinke the contrary. So that (if there be cause) they may as well and safely then purge, as at any other time: Or, if occasion shall urge, as in plethoricall bodies, and many other cases, a veine may safely (or rather most commodiously) be then opened and so much blood taken away, as the skilfull Physitian shall thinke in his discretion and wisdome to be needfull and requisite.
Let no man here think, that this is any strange position, or a new paradoxe (for the learned know the contrary) or that I am studious of innovation, but rather desirous to roote out an old and inveterate errour, which in all probabilitie hath cost moe Englishmens lives, then would furnish a royall army, in neglecting those two greater helpes or remedies, to wit, Purging, and Blood-letting in hot seasons of the yeare: which in all likelihood might have saved many of their lives, while expecting more temperate weather, they have beene summoned in the meane time, or interim by the messenger of pale death to appeare in an other world.
Wherefore let all those who are yet living, bee admonished hereafter by their examples, not obstinately and wilfully to eschue and shunne these two remedies in hot seasons, and in the time of the Dog-dayes, (much lesse all other manner of physicall helpes) not once knowing so much as why, or wherefore, and without any reason at all, following blind and superstitious tradition, and error, haply first broched by some unworthy and ignorant Physitian, not rightly understanding Hippocrates his saving in all likelyhood, or at least wise misapplying it. Which hath so prevailed in these times, that it hath not onely worne out the use of purging, but also of all other physicke for that season, because most people by the name of physicke understanding purging onely, and nothing else. As though the art and science of Physicke was nothing else, but to give a potion or purge. Then we rightly and truly might say, Filia devor avit matrem.
But for as much as most people are altogether ignorant of the true ground or reason, from whence this so dangerous an error concerning the Dog-dayes did first spring and arise, give me leave a little to goe on with this my digression, for their better instruction, and satisfaction: and I will briefly, and in a few lines shew the case, and the mistake somewhat more plainly.
