METEORITES! 



We have JUST ISSUED AN ILLUSTRATED DESCRIPTIVE CATALOGUE 

 OF OUR METEORITES, giving first a chronological list of the falls (descriptive of 

 each individual specimen), under the three classes, SIDERITES, 3IDER0LITES ANT) 

 ZEOLITES, followed by a LIST OF MICRO-SECTIONS OF ^ROLITES FOE SALE, 

 and a chronological list of the CASTS OF METEORITES which were made before cutting 

 the specimens into slices, thus being an exact /ac simile of the size and shape of the meteor. 



These lists are followed by 25 PAGES OF ILLUSTRATED DESCRIPTIONS of 

 some of the more recent masses that have passed through our hands. 



The Index to this Catalogue not only gives IN HEAVY TYPE the names adopted for 

 the Meteorites, but various important synonymous names in smaller type. 



PRICE OF THE CATALOGUE, 25 CENTS. 



If you have METEORITES for sale, or METEORITES 

 that you desire sliced, write to us. 



As in years gone by, we are still the headquarters in this country 

 for MINERALS, ROCKS, FOSSILS, CASTS OF FOSSILS, and 

 Other Natural History Specimens.

SCIENCE 



TENTH YEAR. 



The use of Science by scientific men has increased in the past 

 few months as never before. More than tWO hundred Of the 



leading scientific men and women of America have 



agreed to contribute to the paper during the coming year ; and, 

 as others are constantly joining in this move, to make the paper more 

 valuable than ever, it cannot be long before there will be a body of 



five hundred competent users of this weekly medium 



of scientific discussion. It is our aim to place the paper in the 

 hands of all competent persons who will avail themselves of this oppor- 

 tunity to make Science a better representative of American scientific 

 work than ever in the past.
