Gravel, or a sort of Viscous Claiy Matter, which T take to be the chiefCauseof the Generation ol theSftwe, falls into the Bladder, ’tis suddenly andeasily discharg’d, t’re ir can Cohere toget'ner, and form a Stone of any largeBulk : wh ch cannot so frcquently happen in Men, by Reasin of the narrow-ness, crookedneß, and length, of the Passage of the Urethra.

However, it sometimcs comesto pass, thateven in JVomen, either frontamore depending or leß elevatcd Posture than ushal in their Bladder ; or thatthe Matter forming theSrcwe Adheres to tonte part of its Membranes, so thatir cannot fall into the Urinary Fajsage, tiil its own Bigness or Gravity forctthIt thither ; Stenes of a very confiderble Bulk arc Generatcd, Bot the manyInstar.ces we meet with of vast Sternes spontaneousty Vuided, are so many Ar-guments front whence, 1 think, one may reasonably infer, That no Woman ib. p: 85.3.need to beoblig’d everto undergothe Painful and Hazardous SeBion of theStore. For fince Nature by her own Power, without the Ailistance of anyHelp or Remedies can disburthen her seif, and forcc away such Large Storesas those described by scveral Authors, we may probably conclude, That n-n s> : p.even those still Larger sif there be any soch bred in Women,) may bebrougheaway byputtingtheBody into a convenient Posture, and soby theHand and Fingers forcing the Stone into the Urinary PaJJ'age, which by Ap-plication of Relaxing and strongly Emollient Remedies may be so Dilated, as togive a free Passage to the Stone without any forceable SeÜion.

The Practicablenefi of this Method, bath been fuccefsfully Demon- ib. p,sirated by Mr. Tbo. Froby, an Ingenious Ch'mtrgeon of Dublin in three In-stances of Fact.

1. The first Instance was Sarah Cook , a Child about 6 Years Old, \vhofor some Years had been so miftrably afflicted with the Stone, and a perpe-tual Incontinency of her Urine, that her Pärents at any Hazard were willing-to attempt relieving her of so violent a Pain, and so foul a Distemper.Whereupon June 8. 1693. the Child being placed in a convenient Posturein a Man’s Lap sitting aerosi a Table, with her Arms tied down to herLegsby a fort of Bandage ufual in these Cafes, the Chirurgeon first Past his Cathe-ter into the Neck of the Bladder, that it might empty it seif of all Urine,btfore he inserted his Dilatory Instrument, or his Speculum Veßca as onemay call it, with which he extended the Urethra as much as polTibly hemight with fafery, and without putting the Child to txtraordinary Pain ;afterwards by help of a Direffory and Forceps gently thrust into the Bladder ,

he brought away the Stores, without any mannet of Inctfion, in about 3 or 4 Fi*. 44,Minutes time, from the Pailing in of his fast Instrument, and put the Pa-tient to so lit le Pain during the Operation, that when it was over, and fhelaid quietly a-bed, fhe fiept without any Opiate 7 or 8 Hours together, asfhe had not done many Months before; and was in a short time persectlywe'l and at Ease.

2. The second Instance was Elizs. Mortinser , about 10 Years of Arte,who had been troublcd with an Invoiun'arj Distilhng of her Urine, and o-ther Painful Symptoms of the Stone, for, these 3 or 4 Years past; but onJunen. 1693. She Ilias happily relievcd by the Extratho» of a lavge Stone,
