Tassin, Wirt. On the occurrence of 



calcium sulpliide (Oldliamite) in tlie 



Allegan roeteorite. 



Proc. U. 8. Nat. Mns., 

 XXXIV, No. 1622, Aug. 19, 

 1908, pp. 433, 434. 

 While working over some frag- 

 ments of the Allegan, Michigan, 

 meteoric stone, it was noted that 

 certain portions gave a marked 

 evolution of hydrogen sulphide 

 under conditions that led to the 

 belief that some other sulphide 

 than troilite was present. Further

analysis led to the conclusion that 

 the mineral thus decomposed was 

 Oldhamite, though the same was 

 not determined microscopically. 



On meteoric cbromites. 



Proc. U. 8. Nat. Mus., 



XXXIV, No. 1628, Sept. 



15, 1908, pp. 685-690. 

 The writer gives the results of 

 his own analyses on chromites 

 from the Admire, Mt. Vernon, 

 Canon Diablo, Hendersonville, and 

 Allegan meteorites, comparing 

 them with other available analy- 

 ses, and concludes that " the ma- 

 jority of the meteoric chromites 

 contain magnesia and alumina ; 

 and that there is little, if any, 

 relation existing between the 

 amounts of the constituent oxides."
