PREFACE. 



THE greater number of the papers are botanical, 

 and these, I hope, will be found to contain some 

 new and original views. The remainder, dealing 

 with the animal world, though not, I trust, mere 

 transcripts, owe more to such previous and more 

 serious works as those of Mr. Darwin, Mr. A. R. 

 Wallace, Mr. Herbert Spencer, and Professor 

 Weismann. I ought also to express my indebt- 

 edness in the botanical portion to Dr. Bentham, 

 Sir Joseph Hooker, Professor Sachs, and other 



standard authors.
