132 NEW YORK STATE MUSEUM 



a colossal turtle; specimens of the cranium and tusks of 

 Elephas ganesa, the skull of a mastodon, and skull of 

 Dinotherium. 



Mineralogy. 5000 specimens, classified and consecutively num- 

 bered according to Dana's System of mineralogy, representing a 

 great majority of known mineral species, showing crystalline 

 and amorphous forms of the mineral. The specimens are 

 largely from European localities — the rich mining regions of 

 Cornwall, Saxony and Hungary having furnished many of the 

 choicest masses of ores and most brilliant crystals. Among the 

 largest groups are the fluorites, the quartzes and the calcites. 

 There are also special collections in illustration of crystallog- 

 raphy and other structural and physical properties of minerals. 

 Economic geology. A new department, and divided into carbon 

 minerals, ores, and building and ornamental stones. 



Phenomenal geology. A large variety of material illustrating 

 the phenomena of rock structure and formation, and many inter- 

 esting points in dynamic and physical geology. Here are huge 

 columns of basalt from the Giant's Causeway, and the Rhine 

 valley; volcanic bombs from the extinct volcanos of central 

 France; veins of the several kinds in larger rock masses; con- 

 torted and folded strata; metamorphosed rocks; jointed struc- 

 ture; ''slickensides"; faults; flexible sandstone; glaciated rocks; 

 rounded drift; ripple marks; impressions of rain drops; mud 

 cracks, etc.; a large number of septaria, clay stones and other 

 concretions. 



LitJiology. 3000 specimens classified according to Dana's 

 Manual of mineralogy and petrography. 



A large number of the specimens were collected hj Prof. 

 Ward from the localities where specific rocks were first 

 described. Disposed in the drawers are special collections rep- 

 resenting the geology of characteristic regions; among these 

 are 150 specimens from Vesuvius, once in d'Archaic's cabinet, 

 180 from Tuscany, 100 from Mt Blanc, 120 from the Paris Basin, 

 80 from Saxony, 200 from central France, and several hundred 

 collected by the state geological survey, representing the New 

 York strata.
