Now the following is much stronger evidence still. All who go afoot through snow or great cold, and become over-chilled in feet, hands or head, suffer at night very severely from burning and tingling when they come into a warm place and wrap up; in some cases blisters arise like those caused by burning in fire. But it is not until they are warmed that they experience these symptoms. So ready is cold to pass into heat and heat into cold. I could give a multitude of other proofs. But in the case of sick folk, is it not those who have suffered from shivering in whom breaks out the most acute fever? And not only is it not powerful, but after a while does it not subside, generally without doing harm all the time it remains, hot as it is? And passing through all the body it ends in most cases in the feet, where the shivering and chill were most violent and lasted unusually long. Again, when the fever disappears with the breaking out of the perspiration, it cools the patient so that he is far colder than if he had never been attacked at all. What important or serious consequence, therefore, could come from that thing on which quickly supervenes in this way its exact opposite, spontaneously annulling its effect?Or power. Or what need has it of elaborate treatment?
