METHOD OF DISCOVERY. 59 



conclusion. And, by the help of farther reasoning, 

 which, if drawn out, would have to be exhibited in 

 two or three other syllogisms, you arrive at your final 

 determination, "I will not have that apple." 80 that, 

 you sou, you have, in the first place, established a law 

 by Induction, and upon that you have founded a De- 

 duction, and reasoned out the special conclusion of the 

 particular case. Well now, suppose, having got your 

 law, that at some time afterwards, you are discussing 

 the qualities of apples with a friend : you will Bay to 

 him, "It is a very curious thing, — but I find that all 

 Hard and green apples are sour!" Your friend says 

 to you, " But how do you know that \ " You at once 

 reply, "Oh, because I have tried it over and over 

 again, and have always found them to be so." Well, 

 if we w T ere talking science instead of common sense, we 

 should call that an Experimental Verification. And, if 

 still opposed, you go farther, and say, il I have heard 

 from the people in Somersetshire and Devonshire, 

 where a large number of apples are grown, that they 

 have observed the same thing. It is also found to be 

 the case in Normandy, and in North America. In 

 short, I find it to be the universal experience of man- 

 kind wherever attention has been directed to the sub- 

 ject." Whereupon, your friend, unless he is a very 

 unreasonable man, agrees with you, and is convinced 

 that you are quite right in the conclusion you have 

 drawn. lie believes, although perhaps he does not 

 know he believes it, that the more extensive Verifica- 

 tions are, — that the more frequently experiments have 

 been made, and results of the same kind arrived at, — 

 that the. more varied the conditions under which the 

 same results have been attained, the more certain is
