HOPPER. 



Henry County, Virginia. 



Here alto Henry County. 



Latitude 36 54' N., longitude 76 5' W. 



Iron. Medium octahedrite (Om) of Brezina. 



Found 1889; described 1890. 



Weight, 1.92 kgs. (4 Ibe.). 



This meteorite was described by Venable l as follows: 



This iron was found by Nathaniel Murphy in Henry County, Virginia, about 4 miles from the Pitteylvania County 

 line, and 0.5 mile north of the dividing line between North Carolina and Virginia, near to Smith River. Murphy found 

 the stone in a plowed field in the latter part of the spring of 1889. He gave it to Col. J. Turner Morehead, of Leaks- 

 ville, North Carolina. Together with Colonel Morehead he searched over the farm, but could find nothing similar to 

 his piece. Colonel Morehead sent the mass to Dr. H. B. Battle, of Raleigh, North Carolina. It weighed 1.7 kg., and 

 the detached pieces, mainly crust, weighed 0.22 kg. This crust broke off along certain lines by a kind of cleavage, and 

 the main mass is permeated with cracks, not irregular and zigzag, but distinct and regular. This cleavage is in two 

 directions. The laminae vary in thickness, but many are about 0.5 mm. The color of the surface is dark bluish-black, 

 mixed with much red rust coming from the lawrenceite. Parts of the soil apparently still cling to the mass. It measured 

 60 by 70 by 75 mm. in its greatest dimensions. Here and there spots were to be seen with bright silvery sheen. It 

 contains a good deal of ferric chloride and crumbles rapidly. Coarse Widmannstatten figures appear on the polished 

 surface without etching.

Farrington 2 suggested the name of Hopper for the meteorite because of the nearness of its 

 place of find to that town. This suggestion has been adopted by later cataloguers. 

 The meteorite is distributed.

HUEJUQUILLA. 



Under this title various Mexican iron meteorites have been included at different times, 

 especially those of the State of Chihuahua. Wiilfing includes the following: Chupaderos, 

 Adargas-, Morito, Rio Florido, Sierra Blanca, and Tule. The first three may be found under 

 their corresponding names in the text of this catalogue, while the last three refer to irons that 

 have apparently been lost. 



HUMBOLDT IRON. 



Alexander von Humboldt brought to Europe in 1811 a piece of meteoric iron which he 

 stated to have been taken from an unusually large mass of iron, 15,000 to 20,000 kg. in weight, 

 found in the neighborhood of Durango. The large mass he did not see himself. Pieces of 

 Humboldt's piece have been distributed in collections under the name of the Humboldt iron, 

 but the original mass from which they came has never been identified. 



It is possible that this larger mass was Morito or one of the Chupaderos masses, but the 

 origin of the Humboldt iron is so uncertain and obscure that there seems no desirable end to be 

 served in continuing the designation.
