pieces at various periods in its course. In all there was per- 

 haps about 3 pounds, although it was supposed at first that 

 there was a whole mine of it. The other pieces were obtained 

 after the 15 lb. piece, and not one of them weighed more than 

 a pound. 



5. On the Powder Mill Creek Meteorite.* 



Through the kindness of Mr. Moritz Fischer, of the Ken- 

 tucky Geological Survey, I am now the possessor of a piece, 

 weighing over 2,000 grams, of the meteorite which Colonel 

 Sublet and Mr. Lenoir found on the ^irm of Elihu Hurnber, at 

 Powder Mill Creek, about eight miles west of Rockwood Fur- 

 nace, on the eastern slope of Crab Orchard Mt., latitude 35° 50' 

 north, longitude 84° 45' west of Greenwich, in Cumberland Co., 

 Tenn. (Rockwood. being in Roane Co.). Tt resembles very 

 closely the Hainholz, Westphalia, 1856, and. the Newton Co., 

 Arkansas, irons, now the Taney Co., Mo. (see p. 470). It is 

 scarcety distinguishable from the latter (see fig. 1), except that 

 in the latter the grains are larger and more readily defined. 

 The specific gravity was found to be 4*745. 



Polished section, natural size. 



Magnified 20 diameters. 



Chloride of iron (lawrencite) is present in considerable quan- 

 tities, and on a number of sections which had. been cut and 

 polished it was perceptible within a short time. It collected in 

 small beads on the piece itself, which will undoubtedly lead to 



* This meteorite is identical with the one described as the Rockwood meteorite 

 in the last number of this Journal, and only facts additional to those already pub- 

 lished in Mr. Whitfield's article are here given, k part of this meteorite was 

 exhibited and described by the author at a regular meeting of the New York 

 Academy of Sciences, May 30, 1887. The name Powder Mill Creek was given to- 

 rt because it fell in Cumberland Co.; Roane Co., in which Rockwood is situated, 

 being adjacent to this.
