2l6 CONCLUSION. 



Let us extend our haystack to the whole land surface of 

 the globe, which is estimated at 52.5 million square miles, 

 and it will hold only 5 250000 oooooo such stacks,. 



To find a needle in a haystack covering all the land of 

 the terrestrial globe, therefore, is a mere child's play in 

 comparison to finding the one chance in our number given 

 above. 



The entire surface of the earth, land and sea, all counted 

 in, amounts to only 200 million square miles. A needle in 

 a haystack covering the entire surface of the earth will, 

 therefore, be 



as i to 20 ooo ooo ooo ooo, 

 which chance is 



50 ooo ooo ooo 



times greater than the one under consideration above. 



Now then, if to find a single needle in a haystack of a 

 square rod base and say about a rod high, is a chance of say 



i in 50 coo, 



then the " selection " of 12 elements to be successful in the 

 sense above given is 



one million times 



more difficult than finding a single needle in a haystack 

 covering the entire surface of the earth, both land and sea. 



In other words, our haystack must be a million times as 

 large as the entire surface of the earth. 



Taking all the planets of our solar system, we obtain only 

 a total surface of about 160 times that of our earth. Even 

 the sun has only a surface of 11,700 times that of the 

 earth. 



The combined surfaces of sun and all planets, therefore, 

 is less than 12,000 times the surface of the earth. 



The haystack covering the surface of all bodies of our 

 solar system, gives us less than the eightieth part of the area 

 required for the haystack to contain the single needle which 

 to find will be equal to the chance of our twelve elements 

 having atomic weights terminating in .00 exactly. 



For this, our haystack, we need a globe having exactly 

 one thousand times the linear dimensions of our earth. A 

 town lot of 50 by 100 feet on our earth would represent a
