Another diuersitie there is, in the order of these fits: for somtimes they keep due[19] periods or circuits yearly or monthly, according to the falling sicknes, and sometime euery weeke, sometimes[20] euery day, &c. I know a gentlewomã in this towne, who for 2. yeares together neuer missed a fit of the Mother in the afternoone. The like is hereafter mentioned in the Essex gentlewo. who for 16. years altogether had euery day a fit of the Mother at a certaine houre. _D. Argent_ and I had another patient, in whome for 10. weeks together we obserued a fit of the mother euery saturday. I adde _by consent of the Mother_ to distinguish those _Symptoms_ or diseases from such as are caused originally by the part affected. For being procured but by consent, they endure no longer thẽ the fits of the mother do continue. The consent or communitie by which the matrix hath with those principal parts of the body is easily perceiued, if wee consider the anatomy of that part, & the diuers waies whereby it may and doth communicate with them. The fũctions of this part, besides that which is commõ to all other for their nutriment deriued from the naturall facultie, are 2. the one respecting the preseruatiõ of the whole body, as it is an _Emunctory_ of diuers superfluities which do abound in that sex. The other for the propagation of mankind, where it is to be conceiued and nourished vntill it be able to appeare in the world. In regard of these offices this part hath neede of great varietie of prouision, according as the vses are manifold. The substance is neruous, for the great necessitie it hath of sence and motion.

Varelius lib. 4. cap. 3_] It is also _Porous_ for the better entertaining of the vitall spirits and the necessitie it hath of distention and contraction. [Sidenote: _Gasparus Bauhinus historia anatom. p. 71._] It is tied vnto diuers partes of the body that it might the better beare the weight of an infant: backwards by little strings vnto the lower gut, vnto the loines and _os sacrum_: forwardes vnto the necke of the bladder and _os pubis_ by certaine membranes deriued from the _peritoneum_: on each side it is tyed vnto _ossa illii_ by a ligament growing from the muscles of the loynes. It receiueth also for the former vses, vaines from the liuer, arteries from the hart, and nerues from the braine and backe, which are all inserted into the substance of the part, to deriue vnto it the benefit of those 3. faculties, both for the proper vse of the part, and for the vse of propagation and to discharge the whole bodie of diuers superfluities, which otherwise would be an occasion of many infirmities in them.
