Rh expressed was later confirmed by its Secretary. During the Plague Oldenburg wrote from London:

Though we had some abatement in our last week's bill, yet we are much afraid it will run as high this week as ever. Mr Graunt, in his appendix to his Observations upon those bills (now reprinted) takes notice, that forasmuch as the people of London have, from Anno 1625 to this time, increased from eight to thirteen, so the mortality shall not exceed that of 1625, except the burials should exceed 8400 per week.

The case for Graunt is further strengthened by the testimony of John Bell, clerk of the Company of Parish Clerks. The author of the "Observations" asserts that he visited the hall of the Parish Clerks, and used their records in the preparation of his book. Bell, therefore, who was in charge of the Clerks' register, could scarcely have been deceived as to his identity. Now in London's Remembrancer, after explaining and defending the manner in which the bills of mortality were prepared by the Company of Parish Clerks, Bell proceeds:

I think I need not trouble myself herein [i.e., in describing the form of the bills], since that worthy and ingenious Gentleman, Captain John Graunt, in his Book of Natural and Political Observations on the Bills of Mortality, hath already so well described them.

The last of the witnesses in the case is Sir Peter Pett. Born, probably, in 1627, a member of Oxford University while Petty was there, a charter fellow of the Royal Society, Pett was a life-long friend of Sir William, and it is probable that he knew Graunt also. In 1688 Pett published a folio volume designed to vindicate the Earl of Anglesey from the charge of being a Roman Catholic. This gigantic pamphlet discusses many matters not germane to the charge
