 Lord Kelvin made himself responsible for the 

 statement, that while "fortuitous concourse of 

 atoms" is not an inappropriate description of the 

 formation of a crystal, it is utterly absurd in re- 

 spect to the coming into existence, or the growth, 

 or the continuation, of the molecular combinations 

 presented in the bodies of living things. 1 One 

 agrees with the latter part of the statement, but one 

 finds it difficult to entertain the first. What does 

 a "fortuitous concourse of atoms" mean, unless 

 simply a concourse whose antecedent conditions 

 are unknown to us? It cannot mean a chaotic 

 state of things, if it gives rise to one of the most
