No. 1228 Belmont Avenue, Philadelphia, Pa. 
(Professor of Chemistry and Mineralogy; Fellow of the American Association for the Advancement 
of Science ; Life Member of the Academy of Natural Sciences, Philadelphia, and 
American Museum of Natural History, Central Park, N. Y. City.) 
My Mineralogical Catalogue of 100 pages is sent post-paid on receipt of 
25 cents; heavy paper, 50cents; bound in cloth, 75 cents; naif sheep, $1.00; 
half calf, $1.25; cloth, interleaved, $1.00; half sheep, interleaved, $1.25; half 
calf, interleaved, $1.50; (price-list alone, 16 pp., 3 cents). It is profusely illus¬ 
trated, and the printer and engraver charged me about $1,100 before a copy 
was struck off. By means of the table of species and accompanying tables, 
most species may be verified. The price-list is an excellent check list, con¬ 
taining the names of al 1 the species, and the more common varieties, arranged 
alphabetically and preceded by the species number. The species number in¬ 
dicates the place of any mineral in the table of species; after it will be found 
the species name, composition, streak or lustre, cleavage or fracture, hard¬ 
ness, specific gravity, fusibility and crystallization. I have very many species 
not on the price-list, and some that I had in 1876 are no longer in stock. 
Collections of Minerals for Meats, Amateurs, Professors, 'Pljsicians, et al. 
The collections of 100 illustrate all the principal species and all the grand 
subdivisions in Dana and other works on Mineralogy; all the principal Ores, 
etc., etc. The collections are labeled with printed labels, that can only be 
removed by soaking. The labels of the $5.00 and higher-priced collections 
give Dana’s species number, the name, locality, and in most cases, the com¬ 
position of the Mineral; the$5.00, and higher, are also accompanied by my 
Illustrated Catalogue and table of species. 
I have now over forty tons, and over $50,000 worth of Minerals, mostly 
crystallized, in stock. It is well recognized that my prices are lower and my 
specimens better labeled than those of any other dealer in the country. This 
is mainly due to the immense stock I carry (the largest of minerals of any in 
the country) and my system of printed labels attached to the specimens. 
Catalogue of 2,500 species of Shells, made for me by George W. Tryon, Jr., 
who has labeled nearly all my shells, 3 cents; printed on heavy paper, with 
genus label list, 10 cents. I have purchased one or two of the most celebrated 
collections known, and have now over 2,000 pounds, 3,000 species, and 30,000 
specimens of Shells and Corals in stock. Catalogue of Birds, Eggs, Eyes, 
Skins, etc., etc., 3 cents. Catalogues of Books, 16 pp., each 3 cents. Medicine, 
etc., 48 pp., 5 cents. (Please specify exactly what class of books you wish 
catalogues of.)
