 which is not over the bulk of the price, but over the 

 last halfpenny. 



Shall we say, then, that a baby of a day old sucks 

 (which involves the whole principle of the pump, and

 pneumatics and hydrostatics), digests, oxygenises its 

 blood (millions of years before Sir Humphry Davy 

 discovered oxygen), sees and hears — all most difficult

 insignificance ? Shall we say that a baby can do all 

 these things at once, doing them so well and so 

 regularly, without being even able to direct its 

 attention to them, and without mistake, and at the 

 same time not know how to do them, and never have

A man may make a lucky hit now and again by 

 what is called a fluke, but even this must be only
