CATALOGUE OF THE COLLECTION OF METEORITES. 8I 
Saline, crystalline spherical chondrite, Cck. 
Study of the specimens of some falls in the collection has seemed to 
indicate that their present accepted classification is incorrect, and accord- 
ingly the following changes are recommended : 
Baratta—Intermediate chondrite, Ci, instead of black chondrite, Cs. 
Bridgewater—Medium octahedrite, Om, instead of fine. octa- 
hedrite, Of. 
Indian Valley — Hexahedrite, H, instead of brecciated hexa- 
hedrite, Hb. 
Lan¢on—Brecciated gray chondrite, Cgb, instead of white chon- 
drite, Cw. 
Tysnes—Brecciated intermediate chondrite, Cib, instead of brecci- 
ated gray chondrite. 
The additions received to the collection since its inception in 1894 
have been obtained by gift, exchange, and purchase. ‘The accessions by 
gift include a large Cafion’ Diablo individual, from the Ed. E. Ayer 
Pioneer Hose Co.; a small individual of the same fall, from George Bell ; 
a small individual of the Estherville fall, from A. E. J. Svege ; and sec- 
tions of the Allegan, Oakley, and St. Genevieve County meteorites, from’ 
Prof. H. A. Ward. General G. Murray Guion has kindly continued the 
loan of the Seneca Falls specimen. 
Exchanges conducted with a number of institutions and individuals

specimens obtained subsequent to the publication of the first catalogue. 
Each will be found described under the corresponding fall in the body 
of the work. . 
The clerical work involved in the preparation of the catalogue has
