Rose ' mentioned the gift of an individual of this fall weighing 26 pounds to the Berlin 

 collection by J. Lawrence Smith. He also mentions chondri 3 to 4 lines in diameter and remarks 

 that the stones take a good polish. 



Reichenbach 8 has a single reference to the fall, describing a black vein in one specimen as 

 follows : 



The Muskingum specimen in the Gottingen museum has a black vein which runs through the entire stone and is 

 broken off in places, and then affords upon five little specks dark gray striped cracks with metallic luster. A sixth 

 place of the same sort and glistening is crossed at right angles with the first. 



Wright 9 obtained gases from a specimen of the meteorite as follows :

Wadsworth 10 classified the meteorite as a peridotite and made the following observations: 



A crystalline granular rock containing pyrrhotite and iron and showing yellowish brown spots of staining around 

 the latter. 



Section: A light-gray crystalline mass of olivine, pyroxene, and enstatite, and containing iron and pyrrhotite. 

 The groundmass is stained a yellowish brown in many places. 



The enstatite, pyroxene, and olivine are in clear grains when unstained, and are much fissured and broken. 



Some of the enstatite shows the same structure as the chondri of other meteorites except that it wants the cementing 

 base. That is, these grains are formed from minute grains arranged in rodlike forms and lying side by side. The iron 

 and pyrrhotite is in irregular masses and granules. Some colorless irregular patches were observed giving a pale color 

 in polarized light and resembling nephelite. 



Brezina 11 classified the meteorite in 1885 as intermediate chondrite, but later 12 as veined 

 intermediate chondrite. 



The meteorite is distributed. Marietta College has the 103-pound stone and Amherst the 

 51-pound and 34-pound stones. Harvard has 29.361 grams; London, 19,519 grams.
