loins, which occasioned a callous ulcer, through which pus and urine were 

 perpetually flowing. Neither time, nor any of the remedies employed, afforded 

 him any relief; but the passage through the loins closing, and the matter taking 

 a different course, an acute fever was at length brought on, of which the patient 

 died. And the late Mr. Cheselden observes, that he had 3 patients from whom 

 he had extracted small stones, which had made their way from the kidnies to the 

 integuments, and there occasioned an imposthumation. But cases like these, 

 though not perfectly new, seem to deserve to be recorded, as very rare ones, 

 especially when they afford more interesting circumstances than seem hitherto 

 to have occurred. 



XIII. The Disparition of Saturn s Ring, observed by Joseph Varelaz, Lieut, 

 of the Royal Navy of the King of Spain, and Prof, of Mathematics, &c. 

 Translated from the Spanish, p. 112. 



It has been my luck to observe the celebrated phenomenon of the ring of 

 Saturn, which was so much recommended to astronomers, in the gazette of 

 France of July '23. From the 24th of September to the 4th of October, I saw 

 clearly and distinctly the two ansae of the ring; but with this particular circum- 

 stance, that the occidental ansa appeared more strongly illuminated than the 

 oriental. The atmosphere was thicker on the 5th, and I could only see the 

 occidental. The 6th, I thought I could discern some faint remains of the ring; 

 but that might be a deception of my sight, because the atmosphere remained 

 very thick, and the planet could not be seen well terminated. On the 7th, the 

 atmosphere being more transparent, and the heavens clearer than I have ever 

 seen them, I observed the total disparition of the ring; and, having repeated 

 the same observation the following day, I was convinced that this famous phe- 

 nomenon took place the 6th of the month, in which determination I have all 

 the exactness which can be expected in observations of this kind. The most 

 striking circumstances of this phenomenon were the following; 1. The occi- 

 dental ansa constantly appeared more bright than the oriental. 2. On the disc 

 of the planet, one could clearly distinguish the line of the shadow projected from 

 the thickness of the ring. 3. On the extremities of this, some luminous points 

 were perceived, which reflected the light more strongly than the others. 4. I 

 did not observe a sensible variation in the apparent diameter of the ring. 



XIV. Of the Gillaroo Trout. By the Hon. Daines Barrington. p. 11 6. 



" You will find on the table a Gillaroo trout, as it is termed in Ireland, the 

 peculiarity of which is, that the stomach very much resembles the gizzard of a 

 bird. Since that time I have endeavoured to procure a specimen, with the 

 entrails adhering, and have at last succeeded, the stomach on the table having
