358 G. P. Merrill— New Stony Meteorite. 



tered throughout the ground in a manner closely identical 

 with that of the Mil en a meteorite, as also figured by Tscher- 

 mak.* 



As noted above, the stone is traversed by . fine, thread-like 

 black veins, though how abundant such may be it is impossible 

 to tell without breaking the specimen, and this the writer has 

 not been able to obtain permission to do. 



The fall adds one more — the twelfth — to the remarkable list 

 for which Kansas has become noted.f 



As will be seen from the description, the stone belongs to 

 Brezina's group of veined chondritic meteorites (Cwa). It will 

 be known as the Modoc, Scott County, meteorite. 



Chemical analysis, by Wirt Tassin. 



The native metal was determined in 2*0255 grams of the 

 crust-free meteorite as follows : The finely pulverized mate- 

 rial was treated in the cold with a solution of mercuric ammo- 

 nium chloride, in an atmosphere of hydrogen. The results were : 



Fe _-. 6-56 



Ni -. 0-68 



Co 0-034 



The sulphur was determined in 1-0300 grams of the meteor- 

 ite, after fusion with JS"a 2 C0 3 +K]NrOg. This yielded : 



S _. 1-38 



The phosphorus was estimated in 1*0450 grams, and the per- 

 centage found was : 



P . 0-051 



The soluble silicates were determined by treatment with 

 HC1, sp. 1*06. The action was allowed to take place on the 

 water-bath and continued but two hours. The acid then 

 decanted off and the operation twice repeated. This treatment 

 gave : 



SiO„ 17-38 



FeO" 10-95 



A1„0 3 0-20 



Ca"0 0-14 



MgO._ 17-73 



The insoluble silicates were determined after fusion with 

 Na 5 C0 3 . The alkalies were necessarily determined in a sepa- 

 rate portion. Chromite was not present :
