264 PHILOSOPHICAL TBANSACTIONS. [aNNO 1/05. 



caster, the Roman Danum, where the Praefectus Equitum Crispianorum resided, 

 and one from Cunsbrough, or Coningsburgh, an ancient seat of the kings dur- 

 ing the Saxon heptarchy. They were found so near the highway that the cart 

 tracks had worn the earth off the top of the urn containing them. Upon fur- 

 ther digging, there was found another theca nummaria, full of copper coins, 

 as the former was. Both the urns were large and entire, the larger one might 

 contain 2 gallons ; by the fragments, the urns having been accidentally broken, 

 they appear to have been of a finer clay than those found at South Holland, in 

 Lincolnshire, mentioned in the Phil. Trans. N° 279, and the coins also much 

 better preserved by being in a drier soil. Of 6o I bought of those found at 

 Fleet, in that county, there was not one before Gallienus, nor after Quintillus ; 

 and of near 150 of these from Clifton, there is not one of an older date : so 

 that both those in Holland and these in Yorkshire seem to have been hid in 

 some common calamity that followed the death of that short-lived emperor 

 Quintillus, who reigned only 17 days, Anno Dom. 271. And within 6 years 

 after^ we find that Probus the emperor, on some commotions in Britain, sent 

 over certain Vandals and Burgundians, who had invaded Graul, to inhabit Bri- 

 tain; upon whose arrival, probably such as had made the insurrection, might 

 conceal their treasure, and being slain in the conflict, it lay hid till now. This 

 I consider as a more probable conjecture than the persecution of Dioclesian, 

 which was not till 34 years after. These, though they have not added one 

 emperor to my collection, yet have they made a very considerable addition to 

 the variety of reverses : so that I have above 30 of Gallienus.

This author having made several experiments about drowning, and being dis- 

 satisfied with the various opinions that were held concerning it, was induced 

 to write this present treatise, in which he relates these following cases as matters 

 of fact. 



On dissecting a drowned dog, that had been one hour under water, the abdo- 

 men appeared to be a little distended, as did likewise the stomach and intestines 

 in a small degree; but no water was found in either of them. The lungs were 

 likewise distended, but not more than the stomach or intestines, and appeared 

 exactly as those in dogs that are hanged. An incision was made into the trachea, 

 on which they sank down immediately. This at first made a great noise, the
