ing 300 grains, and a ball of lead weighing 140 grains ; and neither of them was 

 broken. 



These bottles are thicker at the bottom than the neck. The glass-maker 

 blows them, and lets them cool, without putting them again into the oven. And 

 from the experiments Dr. B. noticed, that what is capable of breaking them, 

 ought to have some roughness : and he was told that a grain of river-sand will 

 break them. 



Concerning two Ancient Camps in Hampshire. By Mr. Tho. IVright. 



N''475, p. 273. 



Common report, and his own natural curiosity, led Mr. W. to a place in 

 Hampshire called Buckland castle, or, more vulgarly, the Rings, where he 

 found 2 neighbouring camps, about 3 furlongs asunder : the one very strong, 

 with double ditches, and triple Valiums, on the top of a hill, 3 ways guarded by 

 a natural ascent; the other on a lower ground, close by a river, which defends 

 it on one side, with a ditch and vallum half round, and a kind of morass on the 

 other. The first contains about 10 acres ; the latter about 7 ; and the land 

 lying between them is, and has been time out of mind, called Ambrose farm : 

 besides an arm of the river, or rather of the sea, it being salt water, running 

 close up to the latter, is called Ambrose dock. From all which it appears not 

 improbable, that this may have been a principal station belonging to Aurelius 

 Ambrosius. 



Camden, though he takes no notice of these camps, yet mentions one of 

 much less consequence, at about 12 miles distance, called Castle Malwood, says, 

 " It is most certain, that about the year 508, Aurelius Ambrosius had here many 

 conflicts with the Saxons, with various success." But, again, the people of the 

 country have a tradition, that 3 miles to the west of this camp, a famous battle 

 was fought between the Saxons and the Danes ; in which so much blood was 

 spilt, that a little river is said to have run blood, now called from thence Danes 

 Stream. 



Observations on a Case published in the last Volume of the Medical Essays, Edin. 

 1744, &c. of Recovering a Man dead in Appearance, by distending the Lungs 

 with Air. By John Fothergill, M.D. N° 475, p. 275. 



There are some facts which, in themselves, are of so great importance to 

 mankind, or which may lead to such useful discoveries, that it would seem to 

 be the duty of every one, under whose notice they fall, to render them as ex- 

 tensively public as possible. 



The case which gave rise to the following remarks, seems to be of this nature : 

 it is an account of " a man dead in appearance, recovered by distending the lungs
