 IK>{ a poisonous vapour. 



He aftetward advanced bis face to the surface of the 

 vapour, and took --in breath gently. He was sensible of 

 something sufi'urathig, just like the air of a hot and 

 moist stove: Likewise he felt, a slight acrimony in the 

 throat and nose, -which made him cough and sneeze : 

 lw.it no hcad-ach, no sickness at "-stomach, nor any other 

 inconvenience. 



It is clear then upon the wln>le, that animals die in : 

 this^apour, not as poisoned, but rather as drowned, 

 in a fluid not capable of supplying the place of the air, 

 which 'is necessary for respiration, and equally necessary 

 to sustain tire, as the flame of a lighted flambeau. 



2^, A 'fire of a strange miture appeared 'in Wales, 

 about Christmas, l6'f|3v A fiery vapour came from the 

 sea, and moved up and down for many weeks. It set 

 on fire sixteen ricks of hay, at Harlech, in Merioneth- 

 shire, and two barns, and annoyed the country, as well 

 by poisoning the grass, as firmg the hay. It was a blue, 

 .weak flame, and did no harm to the men who tried to 

 save the hay, though they ventured even to touch it. 

 An intelligent person who lived near Harlech, informed- 

 his friend some time after, "The fire still continues* 

 there. It covers over a part of the sea, from a marshy 

 place in Carnarvonshire, eight or nine miles off. The 

 grass over which it moves kills all manner of cattle that 

 i'eed upon it," sheep, goats, swine, cows, and horses. But 

 what is very remarkable, is, that any great noise, as > 

 beating a drum -or sounding a horn, effectually repels it 

 from any house j. or barn, or stack of hay/' 



25. A much stranger flame than that which issues 

 out of the earth, is that which issues out of the stomach 

 *>f animals. The anatomical lecturer at Pisa, m the 

 year 1597, happening to hold a lighted candle near the 

 subject he was dissecting, on a sudden set on fiie the va- 

 pours that came out of the stomach he had just opened. 

 In the same year, as Dr. Ruisch, then anatomy profes-
