3 4 o MOSTLY MAMMALS 



the Indian Ocean in a state of nature we know practically 

 nothing, owing to the fact that in South Aldabra alone 

 are any members of the group living in a wild condition, 

 and that accurate observation is there practically impos- 

 sible. Of the mode of life of the Galapagos species we 

 have comparatively full accounts ; but limitations of space 

 render it impossible on the present occasion to refer 

 further to these species, either as regards their distinctive 

 characteristics or their history and habits. I have only 

 to add that readers of this volume are indebted to Mr. 

 Rothschild for the loan of the photograph illustrating 

 this article.
