. arc coming on Places, yet fo far as I can inform my 
felf, it has often and for the moft Part been obferved. 
It was fo in the dreadful Shake at J cHrMUtcci thirty odd 
li^ears ago ; and a moft ingenious and oblerving Friend 
of mine who had his Leg broke on the Point when it 
funk and is ftill living, tells me, That after that Shock, 
which was follow’d with many Tremblings and lefter 
Shakes while his Leg was healing, he could from

blue Flame of the Sulphur would plainly arifo, and 
give a fmall Scent, and but a fmall one. By this it 
feems evident that it was a fulphurous Blaft which 
burft open the Ground, and threw up the calcin’d bi- 
tuminous Earth. The Family neareftto thisEruption,
