A work for reference or continuous reading, at once popular and, in the modern sense, 
thoroughly scientific. The new edition is practically identical with the former four-volume 
edition except that the colored plates in the latter have been omitted. The wood-engrav- 
ings, over two thousand in number, have been retained. 
Prof. Fohn M. Coulter, in THE Dia: ‘Prof. Kerner has brought the most recent re- 
searches within reach of the intelligent reader, and in a style so charming that even the 
professional teacher may learn a lesson in the art of presentation. . . . It is such books as 
this that will bring botany fairly before the public as a subject of absorbing interest; 
that will illuminate the botanical lecture-room.” 
Prof. Chas. R. Barnes, in THE BOTANICAL GAZETTE: ‘This lucidity, and the ex- 
cellent illustrations, not only will introduce the non-botanical reader to the science of 
botany, but should serve as a lesson to the professional botanist in the art of presenta- 
tion.” 
The Nation: ‘‘He has succeeded in constructing a popular work on the phenomena of 
vegetation which is practically without any rival.”

‘Science: ‘*The volume is full of original suggestions and differs quite markedly from the 
old-time works devoted to plant physiology.” : 
William F. Ganong, Professor in Smith College: ‘‘T am much pleased with the clear- 
ness, proportion, and vigor with which it treats the subject. It seems to me an admirable 
exposition of the principles of plant physiology as they are understood at 
the present day, and it should have a wide use.
