FROM THE ANATOMY OF A PORPOISE. 61 



and the canals of Nuck and of Gartner of the adult female economy, 

 may have the history of their existence thus read. 



As more and more verae causae assert their existence and vindicate 

 their rights, the ancient realm of Archetypal Ideas will suffer 

 more and more serious curtailment 1 . But like all other failing" 

 empires, it too will find its advocates to speak of it as being an 

 ' essentially conservative power:' though after short campaigns it 

 has, once and again, had to resign some of the fairest provinces in 

 the world of thought, its existence will still be said to be necessary 

 for the preservation of the due ' balance of power * amongst rival 

 biological principles. 



Let us hope that in the interludes of rhetoric the logic of facts 

 may find a moment to make itself heard. It will teach men mundum 

 quaerere non in microcosmo sno seel in munclo majore, to hold of Nature 

 that her ways are not as our ways, nor her thoughts as our thoughts. 

 The notion of type may help man's weakness, but it by no means 

 therefore follows that it regulates Nature's operations ; it may 

 enable us to colligate phenomena, but it may no more for that be 

 the cause of their evolution than the mule's panniers which carry 

 home the grapes are, by virtue of this their function, the cause of 

 the growth of the vine. 



1 Even in Mr. Herbert Spencer's 'First Principles' we find, at p. 22, the following 

 sentence, ' In Biology we are beginning to progress through a fusion of the Doctrine 

 of Types with the doctrine of adaptations ; * and Mr. Darwin, in the last page but one 

 to which we have referred in his writings, speaks of * Homology coming into play ' as a 

 really efficient physical agent.
