208 GEOLOGY AND MINERALOGY. 
Section VII. The Meteorites of this Section occupy a middle place between the 
stone and the iron meteorites. They contain a considerable amount of metallic 
iron. 
First Group—With intermixed Olivine of the finest ecvlour, Mean specific 
gravity==5.0(?) From, 
Atacama, —; Siberia (the Pallas Meteorite), —; Saxony, —; Brahin, —;. 
Bitburg, —. 
Second Group—Mexican Meteorites, also containing Olivine, but with more- 
metallic iron than the Meteorites of the first group. Mean specific gravity 
=6.5(?) From: 
Manji; Tejupileo; Xiquipileo; Bata; Ocatitlan; Istlahuacan. 
Section VIII. Iron Meteorites exhibiting “ Widmannstet’s Figures.” From:

Section IX. Iron Meteorites which do not exhibit the definite crystal markings of. 
those belonging to the last Section— 
First Group—Transition Meteorites to Section VIII. Crystal figures partially 
developed. Meteorites from: « 
Caryfort, G.—,; Zacatecas, G. 7.55. 
Second Group—Containing minute points and needles of white iron. From; 
The Cape of Good Hope, G. 7.50; Rasgata, G. 7-55; Salt River, G. 6.83; 
Kamtschatka, G.—. Ly 
Third Group—Containing iron in irregular masses. From: 
Chester, G.—; Arva, G. 6-81; Caille, G. 7.64. 
Fourth Group—Masses of Meteoric Fron, with subordinate markings in straight 
lines. From: 
Tucuman, G. 7.56; Senegal, G. 7.72; Claiborne, G. 6.82. 
Fifth Group—Entirely destitute of form-markings on the etched and polished 
surface. Meteorites from: 
Tarapaca, G. 6.50; Green County, G.—; Hauptmannsdorf, G. 7.71; Smith-. 
land, G.—. 
Tn addition to the paper from which the above classification is abridged, the: 
Baron von Reichenbach has published in another number of Poggendorff’s Annalen, 
an elaborate essay on the general composition of Meteorie masses. From this. 
paper we extract the following tables—showing the mean composition, as caleu-. 
lated from various analyses, of stony and iron meteorites generally.
