Cæterum, ad minuta secunda quod attinet, nihil audeo certi definire; neque enim hujusmodi Observationes ad id praestandum satis esse arbitror; quae scilicet, vel Instrumentorum defectu, utcunque exiguo, vel refractionum inconstantiâ ab aëris inæqualitate, vel Astronomorum dissidio in Declinationibus siderum statuendis, vix aliquando contingat, ut omni prorsus careant errore; nec si aliquando careant, id ullo poterit indicio deprehendi. Ex praedictis tamen Observationibus, non imprudenter statui potest latitudo Observatorii Regii in aula 38° 42' 20", nostri vero Collegii D. Antonii Magni, 38° 42' 30". Quamquam hæc ipsa secunda prudens neglexi in nonnullis supputationibus, in quibus Elevazione Poli fuit utendum; tum quòd nullum neglecta, aut nullius momenti errorem inducere possent; tum etiam quòd aliarum Observationum indi- cio pauciora, aut penè nulla ea esse viderentur. Mox tamen novis, variisque Observationibus instituendis, ac praesertim magni Gnomonis ope, Augustissimi nostri Regis iussu erigendi, fore spero, ut secundorum numerum congruentius assequamur. Quas hæc observavi Solis, Lunæque Eclipses, observavit R. P. Dominicus Capassus, Conimbrica, quæ, à mense Junio anni proximè superioris 1726. balneorum causâ fecerat; ibique nonnullas etiam instituit Observationes circa Poli Elevationem; ac circa Intimi Satellitis Immersiones, atque Emersiones; quas omnes seorsim exhibebit, unà cum reliquis ab ipso mox habendis in variis hujuscæ Regni locis ad Boream sitis. Deinceps in aliis etiam opportunius instituentur. VII. Some Observations made in the Dissection of three Subjects; by Mr. Ranby, F. R. S. THE First, a Man aged 70 Years, who died of a Suppression of Urine, occasion'd by a Stone stopping in the Urethra, just within the Glans, of the Bigness of a Horse-Bean. This Appearance, with the Symptoms that had attended this miserable Man, gave me Reason to expect something remarkable in the urinary Passages. The Ureters and Pelvis were very much distended; which is common where great Numbers of Stones have descended down them, from the Kidneys to the Bladder. The Bladder contained about sixty Stones, the largest of which was about the Size of a Walnut, the others smaller; and just within the Neck, was a hard Tumour, as big as a Nutmeg, which almost
