tube was filled with a glutinous matter tinged with blood. On the back part of 

 the vesiculas seminales, near the prostata, were several stones, as large as peas, 

 which closely adhered' to the adjacent membranes. 



The second, a boy aged 10 years, killed by a blow on the skull, whose 

 spleen weighed 2 lb. and possessed almost all the left side of the abdominal 

 cavity. The bladder, when distended to its greatest capacity, would not con- 

 tain ] oz. 



The third, a man aged 25, who died of a pocky hectick, and some days 

 before complained of a painful swelling in the testicle, which he said came the 

 night before. Mr. Ranby found it to be a hernia aquosa, and would have punc- 

 tured it, had he not felt, besides the water, a hard body, which he could not 

 reduce. In a few days the patient died. Opening the scrotum, and separating 

 the common membranes to the processus vaginalis, it contained about 4 oz. of 

 water, besides a great part of the omentum; some portion of which adhered 

 to the bottom of the cavity and the albuginea that immediately covers the 

 testicle. 



Observations of the Eclipses of Jupiter's Satellites, from 170O to the Year 1727. 

 By the Rev. JV. Derham, M. A. F. R. S. Communicated by Sir Hans Sloane, 

 Bart. N°402, p. 415. 



These observations are of the eclipses of Jupiter's first four satellites, made 

 at several intervals by Mr. Derham, from the year 17OO to 1727. They were 

 observed with good telescopes, of iS feet or 124- feet long, and the times regu • 

 lated by a meridian instrument.'' The object was, by a series of good observa- 

 tions, compared with calculations made from the existing tables, to apply the 

 observed differences to correcting the tables. Accordingly the observations are 

 accompanied with calculations of the same eclipses, from two sets of tables, 

 viz. those of M. Cassini, and of the astronomer royal at the British Observa- 

 tory. But as we possess new tables of those satellites much more exact than 

 those, and made from more regular and more correct observations than the 

 present ones, these are therefore omitted, as no longer of any use whatever. 



Of a Roman Pavement found near Grantham in Lincolnshire. By JV. Stukeley, 

 M. D. F. R. S. N° 402, p. 428. 



In Feb. 1727-8, ploughing in the open fields of Denton, about 2i miles 

 drom Grantham, they met with a Roman pavement in Mosaic work. It lies 

 lartly in the glebe land, and partly in Madam Welby's. It has been a very 

 rerge room about 30 feet both ways, as was found by digging in divers places;
