EVOLUTION IN NATURAL SCIENCE 3 



The general plan of my lectures has been sketched 

 in the programme. In the first I hope to give 

 a brief account of the doctrine of evolution under 

 the aspect of a scientific hypothesis, and to illustrate 

 my remarks by a series of photographic lantern 

 slides, which I have selected from my special 

 province, viz. the guests or inquilines (i.e. parasites) 

 of the ants and termites, or white ants, because 

 with regard to these creatures I feel most at home, 

 and have not to rely upon the authority of others, 

 but incidentally I shall refer to arguments derived 

 from other departments of science. 



In my second lecture I intend to distinguish, as 

 clearly as I can, between the doctrine of evolution, 

 as a scientific hypothesis, and the same doctrine 

 as a philosophical theory of life, and further, be- 

 tween the doctrine of evolution as resting upon 

 a theistic foundation, and as based upon materi- 

 alistic atheism, and finally I wish to distinguish 

 between Darwinism and the theory of evolution. 



In my third lecture I intend to deal with the 

 application to man of the theory of descent, and 

 to show you a few diagrams by way of illustration. 

 We have arranged to have an evening discussion 

 on Monday in the great hall of the Zoological 

 Gardens. 



When the struggle arose between the Coper- 

 nican and Ptolemaic systems, over 350 years ago, 

 people had no conception how far the new ideas 

 would lead. It was reserved for more recent ages
