their place an outline of the natural arrangement adopted by De 

 Candolle and most modern systematic writers. We think that 

 150 pages devoted to this latter part of the science is almost alto- 

 gether out of place in a book "intended to give the important facts 

 of botanical science as briefly and popularly as possible." 



But we must not be misunderstood. This is an excellent book, 

 and well fitted to follow a "brief and popular" primary volume, 

 such as Henfrey's ' Rudiments.' It will even, we suspect, supersede 

 Balfour's ' Manual' in many places where that has been usually em- 

 ployed : this is a misfortune; for the 'Manual' is far better fitted 

 for the more advanced student than are these ' Outlines.'
