PREFACE vii 



lucid order of the Great Hall of the Natural History 

 Museum, which has been copied in every leading 

 zoological museum in Europe and in the United 

 States, may not be aware that he originated this 

 means of letting nature tell its own story of the 

 laws of evolution within little more than three 

 years after the publication of the Origin of Species. 



His early letters as a young army surgeon in 

 the Crimea, for which service he volunteered, may 

 probably have an added interest when compared 

 with recent experiences in South Africa, and in 

 view of the present invasion of Russian territory 

 by Japan.
