When sections are made of the ovary in this condition, it is found that all traces of the (iraafian follicle have disappeared; or one or two only may be observed, degene- rated into little masses or sacs of cartilaginous hardness. More commonly, however, nothing now remains but a dense parenchyma. Besides these changes in the form of the ovary and the condition of its component parts, great alterations also take place in its vascular supply. In early life, and especially from the establishment of puberty up to the critical age, the organ is abundantly supplied with blood-vessels, which are seen everywhere both in the proper parenchyma of the ovary, and also upon the walls of the ovisacs. These have been described as undergoing enlarge- ment, and probably increasing in number in the neighbourhood of the spot at which the rupture of the follicle occurs. Not only, however, is there a local hyperamia in these situations at each recurrence of the ovipont, but the entire ovary receives a larger supply of blood on these occasions. But when the process of ovulation has entirely ceased, the tissues begin to suffer the wasting of age, the ovary partakes in the general state of pallor of the other pelvic viscera, and the ovarian vessels carry only as much blood as will suffice for the bare nutrition of the shrivelled Please note that these images are extracted from scanned page images that may have been digitally enhanced for
