On May 28 last a farmer of Barntrup, a small town of the Principality of Lippe, in the north-west of Germany, walking in the afternoon, 2h. 30m., on the edge of a neighbouring wood, suddenly heard repeated reports like those of a gun, followed shortly after by an indistinct rumbling as of thunder. At the same time a meteorite came crashing through the leaves of a tree. The rumbling came from a south-westerly direction, the temperature was warm, the sky bright, and almost entirely cloudless. This is the twelfth case of a meteoric fragment being found in the north-west of Germany. It is a monolith of about the sire of a walnut, and weighs I7.3 grammes (specific weight = 3.495)- It is covered with a black crust chipped off in places by the fall. Under this crust it is of a light gray colour and granitic sub- stance, dotted in places with small yellow crystals, which are probably troilite or schreibersite. It has been lately presented to the Detmold Museum.
