IV. A Letter from Mr. Chr. Warren, Surgeon at Truro in Cornwall, to John Machin, Esq; Secr. R. S. Prof. Astr. Gresham. containing further Accounts of the Success of injecting medicated Liquors into the Abdomen, in the Case of an Ascites. S I R, Read May 24. I BEG Leave to return my best Thanks to the Society in general, and to you, Sir, in particular, for their unanimous Thanks to me, and their Approbation of what I communicated to them in relation to June Roman*, whom I tapp'd and injected for a Dropsy, and yet remains in statu quo; tho' she inform'd me Yesterday, that she had labour'd under a Tertian Ague ever since last January: Indeed I should not wonder, if, after Nineteen Months Space, she should want the same Operation again, in a Country where Poison [a Dram] is habitually become the common Nutriment, Physician, and Counselor on all Occasions.

I am, with the greatest Regard to the Learned, Worthy Gentlemen of the Royal Society, SIR, Your most obliged, Truro, May 12. 1744. and obedient humble Servant, Chr. Warwick. V. A Letter from John Bevis, M.D. to John Machin, Esq; Secret. R.S. &c. containing some Observations concerning Mercury. SIR, Presented May 4. 1744. THE Observations to which the inclosed Computations are made by Mr. Morris from somewhat more correct Elements than those in Dr. Halley's Tables, were carefully taken by myself, with an excellent astronomical Sector of five Feet Radius. You will perceive how far I am limited, by my Friend's Request; so must intreat you, if you think it worth while, to inform the
