 an average space of four feet in height, and one foot square, would 

 form a vertical column, havirg for its base the whole surface of the 

 earth and sea spread out into a plane, and for its height 3674 times 

 the sun's distance from the earth ! The number of human straf.i 

 tlids piled one on the other would amount to 460,790,000,000,000.
