which time one may perceive them sometimes to resist, and then again press forward the finger, being more or less hard and extended, according as the pains are stronger or weaker. These membranes, with the waters in them, when they are before the head of the child, midwives call _the gathering of the waters_, resemble to the touch of the fingers those eggs which have no shell, but are covered only with a simple membrane. After this, the pains still redoubling the membranes are broken by a strong impulsation of these waters, which flow away, and then the head of the infant is presently felt naked, and presents itself at the inward orifice of the womb. When these waters come thus away, then the midwife may be assured the birth is very near, this being the most certain sign that can be; for the _amnios alantois_, which contained these waters, being broken by the pressing forward of the birth, the child is no better able to subsist long in the womb afterwards than a naked man in a heap of snow. Now, these waters, if the child comes presently after them, facilitate the labour by making the passage slippery; and therefore, let no midwife (as some have foolishly done) endeavour to force away the water, for nature knows best when the true time of birth is, and therefore retains the waters till that time. But if by accident the water breaks away too long before the birth, then such things as will hasten it, may be safely administered, and what these are, I will show in another section. SECT.
