tlemen, those of Dr. Genth having been furnished me by him 

 in illustration of his celebrated paper on ''The Alterations of 

 Corundum." (3) A valuable contribution from Dr. Joseph 

 Hyde Pratt, state geologist of North Carolina. (4) A valuable 

 series of specimens collected by myself at the celebrated Ruth- 

 erford mines at Amelia Court House, Virginia. (5) A collection 

 of minerals from the upper part of this state obtamed by ex- 

 change from Chicora College at Greenville. In addition to 

 these are many smaller contributions from iridi\'iduals and^ a 

 further accession not yet unpacked from the United States Na- 

 tional :Museum at Washmgton. There is also a considerable 

 series of rock specimens from various parts of this state, partly 

 gathered by myself and partly obtained from various sources, 

 as well as the South Caroliua rocks and minerals in the collec- 

 tion of Mr. Sloan. 



PEECIOUS AND ORNAMENTAL STONES 



The third especial collection is one illustrating precious and 

 ornamental stones, compromising specimens which I have gathered 

 during many years. While by no means complete and neces- 

 sarily consisting for the most part of small specimens, this will 

 present a beautiful and attractive exhibit. 



Rocks 



The Tvluseum already possessed a fair collection of rocks both 

 American and foreign. To these I have added a nearly- complete 

 representation of the paleozoic series of New York State, from 

 Ohio, and numerous volcanic rocks from various localities. 



Fossils 



I have presented to the Museum the greater part of my ex- 

 tensive collections in paleontology. These represent more 

 than 500 specimens ranging from the eozoic through to the exist- 

 ing epoch and illustrating somewhat completely every important 

 period of geological time. This is doubtless much the fullest 

 representation of the paleontology of New York State to be found 

 south of Washmgton, together with much material from other 

 parts of the United States, Europe and elsewhere. 



TERTIARY COASTAL PLAIN FOSSILS 



It has been my desire ever since taking charge of the depart- 

 ment to develop here a collection of the tertiary fossils of the
