The Fourth Dimension.

The fourth dimension of space is a supposed or assumed dimension whose relation to the recognized dimensions of length, breadth, and thickness is ahalogous to that borne by any one of these to the other two. Four-dimen-sional space may be regarded as a hypothetical conception to explain equations of the fourth degree in analytical geometry or as an entity beyond the limitations of ordinary existence. .The treatment , of the,fourth and higher dimensions belongs to the geometry of hyphenface. The concei>tion has been used by some investigators to explain certain superphysical phenomena, which seem otherwise Inexplicable. i
