_Dr._ Pringle’s _Paper read after Dr._ Whytt’s _Letter_.
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.
