I received the highest award given to any one at the Centennial Exposition of 1876. and the 

 only award and medal given to any American for '•Collections of Minerals." Two medals and 

 honorable mention at Paris in 1889. The silver medal for the general display 'Of minerals was 

 the only one awarded an American dealer, and the awards for collections and general display- 

 were as high as those given any other (even French exhibits) of the same character. Over 175 

 tons and 1,003,000 specimens in stock.

 It is profusely illustrated and the printer

 fore 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 all the species to 1892. 

 and the more common varieties, arranged 

 alphabetically, and preceded by the specie?

Collections of Minerals for Students, Amateurs, Professors, Chemists, Physicians et al. 



The collection of 100 illustrates the principal species and all the grand subdivisions in 

 Dana's and other Mineralogies: all the principal Ores, &c. &c. The first hundred includes 

 every species in the list advised in Dana's Manual, and some species like Wulfenite. Vivianite, 

 Labradorite. Datolite. Titanite. that are especially advised by Brush, Nason, Egleston or 

 other writers on Mineralogy and blowpipe analysis; also other species like Turquois. Azur- 

 ite. Microline and Wavellite that are important. The second hundred includes the remaining 

 varieties advised by Dana, and most species advised in text-books on Mineralogy and blow- 

 pipe work. 



Our third hundred includes more rare species and varieties. The 300 include 240 species, 

 nearly all mentioned in large type in Dana's and other text-books on Mineralogy and blowpipe 

 analysis, and a few recent species of much importance not mentioned in them. The collections 

 are labeled with printed labels that can only be removed by soaking. The labels of the Stud- 

 ent's and higher priced collections give Dana's species number, the name, locality, and in most 

 cases, the composition of the Minerals: all the collections are also accompanied by my illus- 

 trated Catalogue and table of species. The sizes given are average: some smaller, many larger. 

 Series up to about 1500 species and varieties are furnished.

No references are given because there are but few institutions in America that have not 

 purchased of me and but few countries where 1 have no customers. 



Many of the scientific men of the country recognizing the advantage of having such an ex- 

 change, have placed copies of their papers in my hands for sale on commission. Our lists of 

 scientific books are sent free on light paper, except the 200 page Medical Catalogue, same 

 price as the Mineral Catalogue. Heavy paper, see page of book abbreviations. 



All American books in print supplied on order. Foreign books obtained to order in a few 

 weeks. Of the second-hand books on my list I have generally only single copies, but when sold 

 I replace them as soon as possible. 



When any book inquired for comes to hand, a memorandum, stating description and price 

 will be sent. In our book catalogues the prices opposite the latest number supersede former 

 prices usually where descriptions are the same. My arrangements for noting the needs of my 

 correspondents are nearly perfect. 



Over 300,000 pamphlets and papers, many uncatalogued. in stock. I will get what you order- 

 ultimately. 



Finally and of the Most Importance.— We must 'especially request our customers to 

 let us know of all mistakes and errors that may occur at our establishment. We can and will 

 gladly rectify them at our own expense.
