210 MY LIFE 



two articles, and this drew attention to them, and brought me 

 a very kind and appreciative letter from the late Frances 

 Willard, who was then in England. 



In i8<~)T I wrote the two articles on the American flora al- 

 ready referred to, and prepared a new edition of my two books 

 on " Natural Selection " and " Tropical Nature," now forming 

 one volume, but from which some of the more technical por- 

 tions were omitted, while two new chapters were added — 

 " The Antiquity of Man in North America," and " The Debt 

 of Science to Darwin." I also wrote two articles on " Appari-

In the year 1893 I was pretty fully occupied with literary

 and its Work," gave an entirely new argument in favour of 

 the ice-origin of valley-lakes in glaciated regions; and I also 

 reviewed two books and wrote a number of letters to Nature 

 on biological and physical problems. In the summer of this 

 year I went with my wife to the lake district — our first visit; 

 we ascended two of the mountains, and I paid particular atten- 

 tion to the phenomena of glaciation, which are everywhere 

 prominent in rounded rocks, glacial striae, and abundance of 

 moraines. 



In the year 1894 I read a paper to the Cambridge Natural 

 Science Club on the question, " What are Zoological Re- 

 gions?" which was printed in Nature (April 26). But my 

 conclusion — that the six regions first defined by Dr. P. L.
