" This is one of the most impressive and suggestive Books on religion that 

 we have read for a long time. Indeed, with the exception of Dr. Mozley's 

 University Sennofis, we can recall no book of our time which showed such 

 a power of restating the moral and practical truths of religion so as to make 

 them take fresh hold of the mind and vividly impress the imagination. No 

 one who reads the papers entitled ' Biogenesis,' ' Degeneration,' ' t^ternal 

 Life,' and 'Classification,' to say nothing of the others in this volume, will 

 fail to recognise in Mr. Drummond a new and powerful teacher, impressive 

 both from the scientific calmness and accuracy of his view of law, and from the 

 deep religious earnestness with which he traces the workings of law in the moral 

 and spiritual sphere." — Spectator.

"Professor Drummond is here at his very best. The article on mimicry 

 especially is worthy to rank with anything ever written by Wallace, Bates, or 

 Darwin himself on this fascinating subject. In the presence of such perfect 

 form, such graphic description of details, such genial humour and subtle 

 reasoning, the critic has nothing to do but quote. The only difficulty is to 

 find one passage more suitable than another for the purpose." — Academy. 



" Professor Drummond is a clear and accurate observer, and as he has had 

 a sound scientific training, and has a real interest in the human side of African 

 life, he is able to present us with pictures of a distinctness and originality not 

 often met with in books of African travel." — Times. 



"It is a charmingly written book. . . . Professor Drummond has not 

 inflicted the entire contents of his note-books upon a long-suffering public ; he 

 has been content with valuable and suggestive results, to compress the sum of 

 his observations into a few well-weighed and well-written pages." — Saturday 

 Review. 



"Professor Drummond has undoubtedly succeeded in conveying to the 

 unlearned multitude a vivid and entertaining picture of the country he deals 

 with." — Athenceum.
