the State would require at least an equal amount of space in addi- 

 tion to that now occupied, or about 1,000 square feet. 



2. Economic Geology. 



The area now occupied in wall cases and floor-room is 180 square 

 feet. Space needed for a proper arrangement and enlargement of 

 the collection, equal to one-half that at present occupied — ninety 

 square feet. 



The specimens of this department no win the new Capitol, which 

 will eventually go into the Museum, would require twice the space 

 now used for this collection, or 360 square feet ; and in order to 

 provide for a proper exhibition of the iron ores of the State we 

 should require an additional space of at least 200 square feet. 



3. Minerals. 



Area now occupied by the general collection in wall cases and 

 table cases is as below : 



One thousand five hundred specimens in cases occupying 413 

 square feet. Additional area required, 200 square feet. 



The New York collection of minerals and ores numbers 1,500 

 specimens, occupying 1,181 square feet. 



In each of these departments one-half more space is necessary for 

 collections now on hand, without providing for future additions, 

 which ought to require double the space now occupied, or an area 

 of 800 square feet. 



4. Paleontology. 

 Palfeozoic. — There are now 11,700 specimens arranged in the cases 

 on the second floor of the Museum, which occupy an area of 2,175 

 square feet, disposed of as follows : 



Square feet. 



In table cases 1, 1 25 



In wall cases 840 



In floor-room 210 



Total area 2, 175 



Of the above number of specimens, 9,000 are from the New York 

 formations. The remainder are chiefly from the coal measures of 

 Pennsylvania and the western States. 



Tiie number of specimens, the property of the State, which are 

 not on exhibition, is upwards of 200,000. Of these, 25,000 are in 

 the Museum in drawers and boxes, 155,000 in 3,200 drawers in the 

 custody of James Hall, 20,000 in boxes in the custody of James Hall. 

 Total number of non-exhibited specimens in Palaeontology, 200,000. 

 From this amount there will be taken tlie specimens occupying 

 about 1,000 drawers for exhibition in the Museum ; a portion of 

 these are typical specimens. 



The addition of this material will necessitate an area of 7,360 

 square feet, or nearly three times the space now occupied by this
