312 Dr. Walter Flight— On Meteorites. 



further particulars of the occurrence beyond the fact that the stones 

 fell in a wood, and could not be discovered. 



1877. — Casey County, Georgia.^ 



A fragment of this iron in the Vienna Collection is stated by the 

 writer to exhibit broad and very regular Widmanstattian figures. 

 The beam-iron averages 2 mm. across ; this iron is almost exclusively 

 developed, with unusually sharp lines of etching. Band and inter- 

 stitial iron are only present in traces, and schreibersite and troilite 

 are not recognizable. 



1878, July 15tli, 245 p.m.— TiescMtz, in Moldavia.^ 



A stone fell at this date, with the usual accompanying noise, within 

 100 paces of some people whose attention was directed by a child 

 four years of age to a small dark clovid, from which a peculiar and 

 increasing noise proceeded. This cloud was suddenly seen to become 

 incandescent, but in no very high degree, and the noise became still 

 more intense when a body was seen to fall from the cloud. The 

 stone was warm when found. The noise was heard about the neigh- 

 bourhood two miles around. The stone was secured and sent on the 

 29th to the Museum of the Technical High School, of Briinn. The 

 meteor appears to have passed over Daubrawic and Sloup, and the 

 path to have been directed from azimuth 108, altitude 40°, or from an 

 apparent radiant in K.A. 68°, N. declination 40°. 



One stone only was found, and all search for other specimens of 

 the fall was in vain. The stone weighs 27*5 kilogrammes, and has 

 the form of an irregular pyramid with an almost square base. 



The entire surface is covered with a black crust, in places of about 

 the thickness of that covering the stones which fell at Pultusk ; on the 

 large convex side, which is called the "breast-side," it is much thinner, 

 and exhibits a radiated character. On the back it is thicker and 

 rougher, and without a trace of the radiated structure. The " breast- 

 side " is free from all great depressions, while the others show them, 

 due probably in part to the original form of the stone, partly to the 

 action of currents of air on the melting surface. The freshly broken 

 surface of the stone is dull ash-grey in hue, darker than the Pultusk 

 stones, the texture finer and more sharply marked than in the case 

 of most of the chondrites. We see many small dull grey or dark- 

 coloured chondra, and splinters and fragments of the same kind, 

 many larger dull grey chondra, also white small chondra and white 

 fragments, the latter far fewer than the former. Between them an 

 ash-grey earthy matrix, and very few yellow metallic lustrous par- 

 ticles. Most of the dark chondra are less than 1 mm. in diameter, 

 those which have a diameter of 1 mm. are fewer, and there are occa- 

 sional chondra which exceed 1 mm. in size ; the largest one had a 

 diameter of 5 mm.
