_Nephritic_ Paroxysms have frequently been observed to obey the Lunar Attraction: _Tulpius_[37] relates the Case of Mr. _Ainsworth_, an _English_ Minister at _Amsterdam_, who had a Fit of the Gravel and suppression of Urine every Full Moon, of which he found no relief till the Moon decreased, unless by Bleeding at the Arm. After his death two large Stones were taken out of his Bladder, and the _Pelvis_ of the left Kidney was enlarged to that degree by the quantity of Urine so often stopt there, as to contain almost as much as the Bladder it self. I was present, not long since, at the Dissection of a Child about 5 or 6 Year old, who dyed of the frequent returns of _Nephritic_ Fits, attended with Vomitings and a _Diarrhæa_. The Kidneys and Ureters were quite stuffed with a slimy calculous Matter, and it was very instructive to see the different degrees of Concretion in the several parts of it, from a clear limpid Water, to a hard friable Substance. Dr. _Groenvelt_, who had tended the Boy in his Illness, observed him to be seized with his Pains at every Full Moon for several Months together, which generally ended with the voiding of a Stone. What Influence the Moon has in _Asthma's_,[38] _van Helmont_ takes Notice, _Exacerbatur Paroxysmus_ (says he) _Lunæ Stationibus, & ævi tempestatibus quas ideo præsentit & præsagit_.[39] And Sir _John Floyer_, who has given us a more particular History of this Disease than any Author, observes, that _The Fits usually return once in a Fortnight, and frequently happen near the Change of the Moon_. 'Tis a more uncommon Effect of this Attractive Power that is related by the Learned _Kerckringius_.[40] He knew a Young Gentlewoman, whose Beauty depended upon the Lunar Force, insomuch that at Full Moon she was Plump and very Handsome, but in the decrease of the Planet so Wan and ill Favoured, that she was asham'd to go abroad till the return of the New Moon gave _Fullness_ to her Face, and _Attraction_ to her Charms. Tho' this is indeed no more than an Influence of the same kind, with that the Moon has always been observed to have upon Shell-Fish, and some other living Creatures. For as the old _Latin_ Poet _Lucilius_ says,[41] _Luna alit Ostrea & implet Echinos, Muribu' fibras Et Pecui addit---- ---- ----_ And after him _Manilius_[42] _Sic submersa fretris concharum & Carcere clausa, Ad Lunæ motum variant animalia corpus._
