IN the present work the Author has endeavoured 

 to give a brief and general outline of the rise and 

 progress of the science of Natural History in 

 Britain. As the great advances in this and other 

 sciences have been for the most part brought about 

 by individual workers, it has been thought desir- 

 able, in consistence with the principle of the Series 

 to which this book belongs, to throw this outline 

 into the form of biographical sketches ; and as 

 some of the most important steps in the develop- 

 ment of the science of zoology have been effected 

 by foreign investigators, it has been necessary to 

 some extent to pass beyond the limits of our own 

 country. 



As the last great epoch in zoology is that marked 

 by the appearance of the ' Origin of Species by 

 means of Natural Selection,' the survey here under- 

 taken ends naturally with the great name of 

 Darwin ; obvious reasons rendering it undesirable
