‘The specific gravity of the mass is 3.8. Some chromite is present, but 
not as much in proportion as is found in the Long Island, Kansas, 
meteorite. 
Some of the smaller individuals of this fall may be seen in the 
general Museum collection on exhibition in the Morgan Hall of miner- 
alogy (No. 404 of the fourth floor). 
LONG ISLAND (KANSAS). 
(Aérolite.) 
Long Island is the largest stone meteorite known, the fragments 
which have been recovered aggregating more then 1,325 pounds in weight. 
The pieces here exhibited weigh together 86 pounds, the largest weigh- 
ing 325 pounds. Some of them show the original external surface of 
the meteorite, but most of them show only fractures. ‘The meteorite 
was found in more than 3,000 pieces scattered over a gourd-shaped area 
only 15 or 20 feet long and 6 feet wide in the northwestern corner of 
Phillips County, Kansas, near the town of Long Island, whence its 
name. The small area of distribution shows that the mass burst just 
as it struck the ground, or that it was broken by impact. The late 
time of bursting is also indicated by the lack of secondary crust on 
the pieces. 
Stony matter makes up about 80 per cent by weight of Long Island, 
the remainder having originally been nickel-iron and _ troilite, now 
partly changed to limonite through rusting. On the polished surfaces 
of some of the fragments in the case the nickel-iron may be seen as small 
shining dots. The stony matter consists essentially of the minerals 
bronzite (one of the orthorhombic pyroxenes), olivine and chromite
