IMPROVED MINERAL COLLECTIONS. 



The rapid strides in the science of mineralogy and the 

 many and important new finds, the best of which natur- 

 ally come to us. make frequent revisions of scientific 

 collections of minerals imperative. It has always been 

 our policy to keep our collections right up to date. 

 Those which we are now putting up are materially better than those which were 

 put up a year ago. and far superior to those put up in 1894 when the last edition 

 of our complete catalogue was published It is safe to state that our collections 

 are 25 per cent, letter than they were in 1894. 



OUR COLLECTIONS OF LOOSE CRYSTALS 



Are not only composed of better crystals, but much more care is exercised in their 

 selection and each collection is accompanied by a catalogue enumerating the 

 forms of the crystals. Prices. $5.00, 310.00, $25.00 and $50.00. 



OUR PHYSICAL COLLECTIONS 



Are unapproached by any others in the market. 



OUR BLOWPIPE COLLECTIONS 



Have just been revised (October, 1901) and any student buying one of them will 

 find it of inestimable assistance in his laboratory work. The leading works on 

 determinative mineralogy have been studied from beginning to end in order to 

 make it certain that everything essential for a student of any one of these books 

 to have is included in our collection of 200 specimens at $8.00, while the 

 smaller collections, 100 for $3.50, 50 for $1.50, 25 for 75c, contain the most 

 important of the species. All of these collections are put up in handsome quar- 

 tered oak compartment boxes without extra charge. 



OUR SYSTEMATIC COLLECTIONS OF MINERALS 



Range in price from 75c. to $1,000, and each collection is so carefully selected 

 that its scientific worth is much more than its price. Our " Dana " Collection, 

 No. 1, 125 specimens averaging 2x2 inches, $10.00, has attained an international 

 reputation, no ten dollar collection ever before on the market being comparable to 

 it. Our " Manhattan " School Collections at $1.00 and $2.00 are meeting with 

 success which would be wonderful were it not so well deserved, over 500 of them 

 having been sold to one school. Our 12-page illustrated leaflet, " Suggestions to 

 Teachers of Mineralogy" quite fully describes them. -
