Dr. Walter Flight — History of Meteorites. 501 



The soluble part, which constitutes more than one-half of the stone, 

 is an olivine in which the ratio Fe to Mg is 1 : 3, the same proportion 

 as that met with in the Linn Co., Shergotty and other meteorites. 

 In the insoluble portion we have a bronzite in which the ratio of 

 these two metals is the same as that of the olivine accompanying it, 

 and as that in the enstatite of the Shalka aerolite. In the latter 

 meteorite the bronzite is not associated with nickel -iron. The con- 

 stitution of these two ingredients of the Hainholz siderolite may be 

 represented by the formulas :

Found 1856 (?).— Jewell Hill, Madison Co., N. Carolina. 1 



This iron has been found by Tschermak to enclose thin plates of 

 troilite like those he recently noticed in the meteoric iron of Ilimae, 

 Desert of Atacama, Chili. (See page 73.) The lamella? are just as 

 abundant and have the same orientation as those of the Chilian iron, 

 and are about one-third the size. According to the analyses of 

 Tschermak and Dr. Lawrence Smith, these metallic masses have nearly 

 the same composition. In a volume of his papers collected and 

 published in 1873, the latter author 2 states that the Jewell Hill iron 

 reached his hands in 1854.

Several notices of this remarkable fall, the larger aerolite of which 

 is preserved in the National Collection, have appeared : three by 

 von Haidinger, and three by 1). Cassels, by 2). Pfeiffer, who sub- 

 mitted the rock to analysis, and 3). by Maskelyne, who studied its 

 minute structure under the microscope. Meunier publishes the 

 results of a lithological study of this stone, which he finds to have a 

 very complex structure, and to present in its leading features great 

 similarity with the meteorites of Cabarras Co. (1849, October 31st), 

 Mezo-Madaraz (1852, September 4th), and Bremervorde (1855, 

 May 13th). Its structure has been described as pisolitic : Meunier, 

 on the contrary, likens it to a coarsely granular grit. The grains 

 composing it are often angular, sometimes more or less rounded, and 

 in each instance have the characters of fragments which have been 

 detached from larger masses : the rock, in short, is a breccia. By a 

 careful examination of the four specimens preserved in the Paris 

 Collection, the author has noted the presence of twelve distinct species 

 of grains: 1). troilite, sometimes in fragments of large size; 2). 

 nickel-iron, in rounded or markedly angular fragments ; 3). greyish 

 green translucent peridot, presenting the appearance of having been 

 rolled ; 4). chromite, enclosed in a whitish rocky matrix ; 5). a grey
