October' 7. About 11.45 p.m., a splendid meteor seen in the S.E., from 

 near Liskeard. "At first it appeared as an ordinary shooting star, but 

 instantly expanded into a ball, apparently between twenty and thirty 

 minutes in diameter, when it became dark red. In its wake followed a 

 stream of light nearly a degree in width, and about twenty degrees in length, 

 of a pale bluish tinge around the ball, but otherwise of a vivid red. Before 

 disappearing, the ball turned to a bright blue, and ultimately burst, emitting 

 a great many luminous fragments, which quickly disappeared." This meteor 

 was also seen at Truro in the same direction, or about E.S.E.
