METEORITES OF NORTH AMERICA. 277 



Locust Grove belongs to the granular ataxites, that is, to those meteoric irons of a granular structure, in which the 

 individual grains show neither a structure of octahedral lamellae nor intercalated twin lamella;. The nickel-iron, 

 according to its chemical composition, belongs to kamacite. Of known meteorites Siratik is perhaps the nearest, 

 since in it also appear upon a spotted groundmass glistening stripes irregularly crossing each other. 



Later, Cohen 4 corrected the statement that Henry County was in North Carolina, and 

 placed it properly in Georgia. 



The meteorite is distributed. Vienna has 381 grams, Chicago 370 grams, the British 

 Museum 365 grams.

LONACONING.g 



Alleghany County, Maryland. 

 Latitude 39° 35' N., longitude 78° 38' W. 

 Iron. Coarse octahedrite (Og), of Brezina 

 Found 1882; described 1892. 

 Weight, 1,260 grams (45 ozs.). 



This meteorite was described chiefly by Foote, 1 as follows: 



A physician residing near the Maryland line of Pennsylvania recently brought to me an iron mass to learn if it 

 was meteoric, and this it proved to be. It was discovered in Garrett County, Maryland, about 12 miles from the post 

 office of Lonaconing, not far from the boundary. It was ploughed up about three or four years ago by a boy in the 

 field. According to an analysis by Dr. Koenig it contains over 11 per cent of nickel and cobalt, the proportion of 

 cobalt being unusually high. It is one of the best octahedral etching irons known, being even more characteristic 

 than most of those that have been used for printing directly on paper. Besides the striking reticulated octahedral 

 structure, it shows a large number of secondary lines regularly disposed with reference to the principal markings. 

 These I believe to be similar to those described by Prof. J. Lawrence Smith, in a Wisconsin meteorite, under the name 

 of Laphamite markings. The original weight was 45 ounces, but it has been reduced by analysis, cutting, polishing, 

 etc., to 36.5 ounces. 



The iron was described by Brezina 2 as follows : 

 An iron of 1.2 kg. weight, in the form of an elliptical cylinder with slightly bent axis. The section shows along 

 the natural surfaces a finely flecked zone of alteration 2 to 9 mm. thick. The lamellae are puffy, taenite well developed, 

 fields predominant, almost entirely filled with a repetition of systems of combs running in many different directions 

 in the same; field less frequently filled with a dark gray plessite. Two large plessite areas show finely shimmering 

 central skeletons. Cohenite grains sometimes occur isolated in the kamacite. The kamacite bands are slightly gran- 

 ular, the kamacite combs much so. 



The meteorite is distributed, the largest quantity (S19 grams) being in the Paris School of 

 Mines collection.

LONG ISLAND. 



Phillips County, Kansas. 



Here also Phillips County. 



Latitude 39° 45' N., longitude 99° 25' W. 



Stone. Veined intermediate chondrite (Cia), of Brezina; Erxlebenite (type 34) of Meunier. 



Found 1891; described 1895. 



Weight, 564 kgs. (1,244 lbs).. 



This meteorite was classified by Brezina 1 in 1S95 as a crystalline chondrite (Ck). The 

 same year Weinschenk 2 gave a petrographic description, as follows: 



From the Long Island, Phillips County, Kansas, occurrence I have at my disposal four pieces, amounting in weight 

 to 20-30 grams. They possess a rusty weathered surface. Many hundred similar pieces were found (in part with 



o The locality is usually given as Lonaconing, Garrett County. The meteorite was found, according to Foote, in Garrett County, but Lona- 

 coning is in Alleghany County.
