at the same time looking through the eye-vane, cut the horizon with 

 the axis. 



N. B. Tn taking the altitude of the stars, a small light must be fixed in the 

 lantern; the less the better. It will be best in forward observations of the 

 sun, to take the altitude of the upper limb, allowing for the semidiameter; 

 and when the sun is very clear, take his altitude by a backward observation, 

 the forward method being chiefly intended for nocturnal observations, and 

 when the sun is too much obscured to give any shade or image. 



A remarkable Case of a Genlleivoman %vho died of a Hydrops Ovarii, after 

 having been topped 57 Times. By Mr. John Belchier, Surgeon. N° 423, 



p. vg. 



In J725, the wife of one Mr. Newberry complained of a pain in her left- 

 side, near her groin, internally, which sensibly increased; and perceiving a 

 swelling in that part, she at first thought herself with child; but having other 

 symptoms not very common with women in such a case, she sent for a physi- 

 cian, who immediately discovered it to be hydropical ; and after following his 

 prescriptions for some time, and finding little or no benefit, she sent for an- 

 other, and so for a 3d and 4th ; and after between 2 or 3 years fruitless trial of 

 proper medicines prescribed by the physicians, growing very big and uneasy 

 with her burden, she was advised to be tapped, to which she accordingly sub- 

 mitted: and on May 6, 1728, sent for Mr. Cheselden, who took from her 

 between 4 and 5 gallons of water. But in a week or JO days after the opera- 

 tion, she perceived herself to fill again, in which state she continued to the 

 1st of July following, when Mr. Cheselden tapped her again, and took from 

 her about the same quantity of water as before. And in this manner she con- 

 tinued to fill and be tapped every 3d or 4th week;* from May 6, 1728, to the 

 3d of March, 1731-2, when she died, in the 33d year of her age. 



During the last 37 times of her tapping, Mr. B. constantly attended her 

 with Mr. Cheselden, when she always, till the last two times, appeared very 

 brisk and lively the whole time of the water's running from her, and was not 

 in the least sick or faint after the discharge, as is usual; and though she was a 

 very thin emaciated woman, she would frequently walk 3 or 4 miles the day 

 before the operation, and most commonly went abroad the 3d day after it. 



* Parallel to this is the case related by Dr. Mead of tlie relict of Sir Gregory Page, Bart. She 

 died in the 56tli year of her age ; and in 67 months was tapped 66 times. In these dilierent opera- 

 tions, there were taken from her 240 gallons of water. These particulars are commemorated upon 

 her monument in Bunhill Fields.
