Problems.

Why is it that the parts of the body that are immersed in hot water do not perspire, even though they are themselves hot?

Is it because the water prevents liquefaction, while perspiration is formed when matter which is not properly attached the flesh is expelled by heat?

Why is it that perspiration is caused neither when the breath is expanded nor when it is held in, but rather when it is relaxed?

Is it because, when it is held in, the breath fills out the veins and so does not allow the perspiration to escape, just as the water in a water clock cannot escape if you turn it off when the clock is full? But when the perspiration does come out, it does so in great abundance, because it has gradually collected during the actual period that it has been checked.

Why is it that cold both causes and stops chilblains, and heat both causes and stops burns?

Is the cause the same in both cases, namely that they cause them by setting up liquefaction and stop them by drying them up?
