METEORITES OF NORTH AMERICA. 347 



not observed in any of the dices prepared but schreibersite is undoubtedly present, as indicated not only by the analysis 

 but by the presence in one dice of a rectangular section of this substance about 3 rnm across surrounded by a border 

 of the graphite-bearing iron. A little of the mineral which remained with the companion slice, broken out in the form 

 of powder by means of a sharp-pointed instrument, afforded a heavy precipitate of ammonium phosphomolybdate when 

 treated in the usual way. 



The irregular lines noticeable in the etching are caused by cracks which penetrate more or less deeply into the Tnsutt 

 An analysis of shavings taken from one of the specimens photographed gave the following result: 



Fe Ni Co P C 



90.79 7.66 0.57 0.27 0.07 =99.36 



The carbon is in the form of graphite. The rather low summation is doubtless due to the fact that the edges of 

 the shavings were not entirely free from traces of the oxidized material of the crust. 



The meteorite is distributed.

Assignable weight, 111 grams. 



Ward states that this meteorite was described in a copy of the Ottawa Weekly Times of 

 April 16, 1896, but the present writer has not been able to secure the issue. No other 

 description seems to exist. Ward possesses 111 grams.

 Stone. Brecciated white chondrite (Cwb), of Brezina. 

 Fell on the morning of June 18, 1881; described 1889. 

 Weight, 3,361 grams (7 Ibs.)- 



This meteorite was first described by Castillo, 1 as follows: 



This meteorite fell in 1876 (?) in the environs of the -village of Jacala. There were found three fragments, weigh- 

 ing 3.361 grams, of which the largest weighed 2,115 grams. These fragments are composed of meteoric feldspar, red 

 olivine, and disseminated meteoric iron. All are enveloped by a black, granular, rugose crust at the contact of which 

 is found some troilite. The largest and smallest fragments are in the collection of Castillo. 



Brezina 2 gave the following further description: 



A white chondrite, breccialike; a stone with an inclination toward Cib, having moreover, the greatest similarity 

 with Honolulu at all points where the abundant armor face formation prevails over the enlarging of crust veins to a 

 black zone of alteration. The crust is deep black, somewhat lustrous; over an infiltration vein 1 cm. wide it has a rib- 

 like fluting. 



The meteorite is somewhat distributed; New York possesses 797 grams; Vienna, 266 grams.
