exact time of the true rising and setting of celestial bodies, together with their 

 respective amplitudes ; because the island lies low, and is land-locked on nearly 

 all points of the compass. Besides, the sensible land-horizon of the Ween is 

 extremely uneven and rugged, the north and eastern parts being some rising 

 hills in the province of Schonen, and the western part is mostly overspread with 

 trees on the island of Zealand ; from the remotest of which coasts the Ween is 

 not distant above three leagues.

Account of some Stones and Plants lately found iii Scotland, and of some Boohs 

 noiv printing there. By Sir Robert Sibbald. N° 266, p. 693. 

 Mr. Lluyde met with several curiously figured stones here, and with some in- 

 scriptions on the Roman wall, and in Icolms Kill, and other places, of which 

 it is likely you may have an account from him. Mr. Sutherland found, last 

 summer, several carious plants growing wild in Anaandale, some of which he had 

 not seen before. I am told Dr. Pitcairn's writings, with additions, are to be 

 published in one volume in quarto, in Holland. We are about the christian 

 poet Sedulius Scotus de Mirabilibus Dei, with notes, from a manuscript of 700 

 years' antiquity. We have herein the lawyers' library, Arator, another christian 

 poet, which is intended to be printed from an old manuscript I have. 



Account of an Aneurism of the Arteria Aorta. By Mr. Lafage, Surgeon. 



N°267, p. 696. 



In the year l685, a servant to the Lord Culpeper had a fall, which caused a 

 heavy pain in the breast. A month after, a musket burst in his hands, which 

 gave so violent a recoil against his right side, that it made him spit blood im- 

 mediately, and so continued for 6 months, A year after, he began to feel a 

 pulsation on that side, and then he spit blood again, which continued ever after, 

 but only in the spring and the fall, till he died. He bled likewise by the nose 

 twice a year, for a month every time. About the year 1696, a tumour began 

 to appear under the right nipple, which growing by little and little, came at last 

 to an extraordinary size; after using some emollient ointments upon it, it 

 suddenly broke, and he died soon after. M. Lafage opened the body, and he 

 found first, that two of the cartilages of ihe ribs were worn off, by the conti- 

 nual pulsation of the tumour, as also part of the sternum bone. The dilatation 

 of the artery began precisely on its trunk next the heart, before it divided itself 

 into the ascending and descending trunks ; and though there is but a little space, 

 yet it dilated itself so excessively, that the bag filled up the whole cavity of the 

 thorax on the right side, and pressed the lungs so much, that they were greatly 

 contracted. The bag adhered by the outside to the mediastinum, to the dia-
