METEORITES OF NORTH AMERICA. 157 



The insoluble portion yielded upon analysis: 



Silica Alumina FeO MgO Lime 



50.08 4.11 19.85 20.14 3.90 =98.08 



From all the circumstances connected with this mineral, its physical characters, etc., it is doubtless a pyroxene of 

 the augite variety. 



The soluble portion, owing to the unavoidable presence of a little iron and pyrites, simply furnished results on 

 analysis that showed it to be mostly olivine. The stony matter as a whole freed as much as possible from pyrites and 

 nickeliferous iron, gave: 



Silica 45.90 



Protoxyd of iron 23. 64 



Magnesia 26.52 



Alumina 1. 73 



Lime 2.31 



Soda 0.51 



Potash 0.64 



Oxide of manganese minute quantity, not estimated. 



Oxide of chrome minute quantity, not estimated. 



Phosphorus minute quantity, not estimated 



Lithia marked reaction with {he spectroscope. 



Sulphur 1.01 



102. 26 



The excess in the footing up of the analyses above 100 per cent is due to the fact that a part of the iron, estimated 

 as protoxyd, is combined with sulphur forming sulphide of iron. 



This meteoric stone is similar in every respect to that which fell March 28, 1859, in Harrison County, Indiana. This 

 meteorite is therefore composed of nickeliferous iron, olivine, pyroxene, protosulphid of iron, with minute quantities 

 of schreibersite, chrome iron, and probably albite. 



Later catalogues mention Danville but give little or no account of it. Brezina 6 classifies 

 it as veined gray chondrite. 



But little of the meteorite is now preserved, the Harvard collection possessing the largest 

 amount (105 grams).

DEAL. 



Monmouth County, New Jersey. 



Latitude 40° 17' N., longitude 74° W. 



Stone. Intermediate chondrite (Ci) of Brezina; Luceite (type 37, subtype 2) of Meunier. 



Fell 11.30 p. m., August 14, 1S29; mentioned 1S29. 



Weight: Unknown, probably about half an ounce (14 grams). 



The first mention of this stone seems to have been in 1S29, 1 though the authorship does not 

 seem to be known. This mention was as follows: 



At Deal, New Jersey, on August 14, 1829, two aerolites fell with black, uniformly irregular surfaces, the interior 

 bright gray with metallic points. A bright meteor preceded its fall, which occurred about midnight. The meteor 

 first rose like a rocket, described a curve, and then exploded. There were some 12 to 13 distinct explosions resembling 

 musketry fire.
