The Figures of Some Very Extraordinary Calculous Concretions Formed in the Kidney of a Woman; Communicated by Mr. Charles Lucas at Dublin

be safely used for a long time, without Danger to Health, I can vouch by my own Experience; for a Quart of Lime-Water, and an Ounce of Soap, has never given me the least Nauseating, Lowness of Spirits, or Abatement of Appetite, and I think I was never better in Health than I am now. My Motive for being so particular in this Affair, is a Desire to be instrumental, by your means, of giving Ease to others in so unhappy a Condition; being firmly persuaded, that what has already so far reliev'd me, will, if prescrib'd, dissolve Stones of greater Magnitude than I suppose mine to be. From Abergavenny, Dec. Your affectionate Brother, 1746. Robert Lucas. X.
