Extract of a letter from Edinburgh, Sept. 8.
We hear from Perthsire, that an uncommon phaenomenon was observed on the water of Isla, near Cupor Angus, preceded by a thick dark smoke, which soon dispelled, and discovered a large luminous body, like a house on fire, but presently after took a form something pyramidal, and rolled forwards with impetuosity till it came to the water of Erick, up which river it took its direction, with great rapidity, and disappeared a little above Blairgowrie.
The effects were as extraordinary as the appearance.
In its passage, it carried a large cart many yards over a field of grass; a man riding along the high road was carried from his horse, and so stunned with the fall, as to remain senseless a considerable time.
It destroyed one half of a house, and left the other behind, undermined and destroyed an arch of the new bridge building at Blairgowrie, immediately after which it disappeared.
As few appearances of this kind ever were attended with like consequences, various conjectures have been formed concerning it.
