Stony-iron, Pallasite (Rockiky group of Brezina) . Mass weighing 

 3,220 grams (original weight 5,460 grams) ; mass weighing 2,048 

 grams, cut in halves and polished ; two complete individuals weighing 

 1,450 and 1,550 grams, oxidized; polished section showing brecciated 

 structure, weighing 203 grams; mass weighing 6,725 grams, now dis- 

 integrated nnd preserved in petroleum distillate. A nmss is known 

 which weighed upward of 7,000 grams, making the weight of all that 

 has thus far been found about 24,436 grams, and it is a safe assump- 

 tion that upward of 30,000 grams must have at one time been in exist- 

 ence. A considerable portion of these have fallen to pieces through 

 the oxidation of the included lawrencite and become destroyed. The 

 polished slices in this collection have been preserved by immersion in 

 a petroleum distillate. Mineral composition: olivine with metallic 

 iron, scheibersite, troilite, lawrencite, and, chromite. The structure is 

 that of a siliceous breccia with a metallic cement. (See pis. 8 and 9.) 



Composition of the metallic portion, as shown by Wirt Tassin's 

 analyses :

 The meteorite is the third of its class thus far known. Nothing is 

 definitely known regarding its fall, the material having been dis- 

 covered by a Mr. W. Davis while plowing, and attention called to it 

 on account of its unusual appearance, which was wholly unlike any 

 of the local rocks of the vicinity.
