THE BRITISH ASSOCIATION AT DUNDEE. 

 SECTION K. 



Opening .Address by Prof. Frederick Keeule, Sc.D , 

 President of the Section. 



It is with more than the normal trepidation natural 

 to presidents that I, who have worked on the border- 

 lines of several biological sciences, undertake the task 

 of addressing the members of this section. As well 

 might a rogue and snapper-up of unconsidered trifles 

 recite his doggerel songs before a bench of learned 

 magistrates. 



Therefore, although I have studied from their works 

 the wavs of presidents, and although I shall strive 

 to keep the path which they have mostly trod, yet 

 should I stray I plead with Autolycus that — 



" When I wander here and there, 

 I then do most go right." 



The addresses which I have consulted show me two 

 alternative models. 



I may take all knowledge for my province and 

 discourse on the progress, of our science as a whole. 

 This is Ercles's vein, a tyrant's vein. Or as a lover 

 of a department of the science and more condoling, I 

 may confine my address to a special branch of botany. 

 Each method has its merits and its drawbacks, and 

 the one is corrective of the other. 



The departmental method depicts the tree of know- 

 ledge in .sympodial symmetry. The branch which the 

 president of one year holds out for our inspection is 

 seen arising from an erstwhile dormant lateral bud 

 far back from the growing point of the branch ex- 

 hibited by his predecessor. Under the magic of the 

 presidential hands the new branch grows as grows 

 the enchanted mango. Like the lean kine, it eats up 

 the fat kine, and by the end of the address it dominates 

 all other branches. 



The general method shows the tree in other guise. 

 As an artist is wont to paint a tree, so the historian 

 draws it on monopodial lines, with branches standing 

 in due subservience to the leader and in strict co- 

 ordination with one another. Together these methods 

 tell the truth, which is that the tree of knowledge 

 grows, like many another broad-leaved tree, by a 

 mixed process of monopodial sequences following upon 

 sympodial developments. 



What is to the specialist, and indeed for a space is, 

 the luxuriant predominance of his branch appears in 

 historical perspective but as a new lateral for the 

 extension of all the sublateral shoots of science.
