to have deducted 3° 7-I-' out of the 15 degrees he assumes for the distance of 

 his cohire from the first star of Aries, which will bring him 225 years nearer 

 to Sir Isaac Newton's time. He is likewise entreated, in the next edition of 

 his dissertations, to be a little more careful of his numbers, than he has been 

 p. 134, 135, and to inform himself in the spherics, so as to give us the right 

 ascensions of the stars truly, from their given longitudes and latitudes. 



Lastly, I would inform him, that the star in the Centaur which Hipparchus 

 describes, as being in his time very near the autumnal colure, was not ^ of 

 Bayer, but certainly <I>, and that anno ineunte 1 69O, its longitude was Scorpio 

 8° 43' 4o", with south latitude 27" 59'. But the colure passing through that 

 star, by the proportion given above, cuts the ecliptic 13° 20' 50' in antece- 

 dence of the star, that is in Libra 25° 22' 50". But 25° 22' 50" give 1827 

 years; therefore the time this star was in the colure, was 137 years before 

 Christ, when Hipparchus flourished, and might very well observe it. 



An Account of a large Stone voided through the Urinary Passage, by a Woman. 

 Communicated by Dr. Richard Beard, F. R. S. Physician at Worcester. 

 N°397, p. 211. 



A poor woman in the parish of Fladbury in Worcestershire, aged 63, about 

 3 years since, was afflicted with the usual symptoms of a stone in the kidneys, 

 and afterwards in the bladder. The fits of pain occasioned by it increased with 

 its bulk, till she was so emaciated, that her case was judged desperate. Finding 

 relief, towards the end of last summer, by a plentiful use of mallow-tea, she 

 persisted in it for a while; when on a sudden, in the presence of some women, 

 she perceived an uncommon weight and force within, which assisting with all 

 the strength and breath she had left, a stone came away with a noise that very 

 much surprised the whole company, and with less pain and effusion of blood 

 then, or soreness afterwards, than might have been expected. She is since 

 easy and in health, and feels no other inconvenience now, but that unavoidable 

 one, an incontinence of urine. 



The stone is of the same colour and texture with others of this kind that 

 have been formed in human bodies. Its weight at present, is, §ij. 3J 55 gr. 

 avoird. When first voided, it was considerably more, several pieces having been 

 rubbed off on both sides. The greatest circumference is 74- inches ; it is 4^ 

 inches round at the thickest place, and the length on the convexity is 4^ 

 inches.
