The advantage gained by this attachment is, that by constantly pre- 

 senting to the cutting wheel new surfaces of the specimen upon the 

 same plane, the capacity is doubled, viz.: by this means a wheel cut- 

 ting in a direct line to the depth of only six inches may be made 

 to cut through a fossil or rock specimen of twelve inches in diameter 

 by the revolution of the turn-table.
