    JBlacJcbee’s Improved Pessary. tempered steel wire so shaped by a series of curves (which curves are iormed in direct reference to the anatomical formation of that portion of the pelvis in which it is to be placed) as to render it in a great measure self-adjusting, entirely supporting the prolapsed uterus. This skeleton having been formed is covered with ^etherized india-rubber or 5 other suitable substance, that is to say, I take a piece of properly tempered steel wire of suitable length and thickness, and with suitable instruments shape it into proper form. The ends of the wire are left disconnected in order to cover the skeleton thus formed with a soft elastic material or other suitable substance. This I do by 10 inserting one end of the wire into a suitably made tube of setherized rubber, vulcanized rubber, gutta percha, or other suitable substance, and having drawn on a sufficient length of the material I draw hack the ends thereof and unite the ends of the wire; the ends of the covering are then brought together and united, or I unite the ends 15 of the wire first and cover it with the aforesaid material by any other suitable means; but I prefer to have the elastic coating detached or loose upon the steel foundation as a tube, as above stated. And in order that my said Invention may be better understood I will now proceed to describe the Drawing accompanying these presents 20 illustrative of the construction of my improved pessary. Description of the Drawing, Figure 1 represents a front elevation of my imjiroved pessary complete shewing the peculiar shape thereof in accordance with the anatomy of the part to which it is to be applied, as above stated; Figure 2, a 25 perspective side view of the pessary shewing a portion of the elastic covering removed at *, *. A marks the tempered steel wire or foundation; B, elastic tube or covering, or there may he two or more tubes passed one over the other; C, D, and E, G, mark the more flexible or yielding parts of the pessary when pressed against, constituting in 30 fact a double self-acting spring, yielding to the movements of the body, as above stated. Having now fully described and set forth the nature and object of my said Invention for “ An Improved Pessary/’ together with the best means I am acquainted with for carrying the same into practical effect, 35 I would remark in conclusion that what I claim as my Invention
