SIR,
Your most obedient humble Servant,

Dr. Pringle's Paper read after Dr. Whytt's Letter.
Read April 21, 1757.
DR. Pringle begs leave to inform the Society, that having read the copy of his letter, within these few days, to Dr. Shaw, Mr. Hawkins, and Mr. Graham, those gentlemen found his account agreeable to their several observations; only Mr. Graham took notice, that, of late years, Lord Walpole, in his journies to Norfolk, had twice voided some blood with his urine, but with little uneasiness; and that at other times had passed some sand and stony particles (tho' never larger than the head of a small pin), attended with frettings of the parts, scarce painful. But Mr. Graham was not sure, whether these accidents were prior or subsequent to the sequel of the case, communicated to the Society by his Lordship.
Dr. Pringle thinks it may be likewise proper to acquaint the Society with another circumstance in Lord Walpole's case, which he had both from Dr. Shaw and Mr. Graham, viz. that after using the soap and lime-water for some time, his Lordship was freed from a very obstinate dry and scurfy eruption, which had resisted several other medicines. But as there were no marks of a putrid scurvy (that species expressly alluded to towards the end of Dr. Whytt's letter) the Society will easily understand, how the lithontriptic medicines may be prejudicial to one troubled with the true putrid scurvy (such as is most incident to sailors) and yet not be improper for those, that are subject to the scurfy eruptions, which are commonly, tho' erroneously, called scorbutic.
