 A history of the nutrition of plants from ancient times to 

 1861. — The particular lectures on which this volume was founded 

 were held in February and March 1880. At that time the author 

 began a continued series of lectures on plant physiology intended 

 to cover the subject as completely as did the famous lectures of 

 Aug. P. De Can d olle. Pedersen continued his lectures almost 

 until his death in 1905. Every subject was treated monographi- 

 cally, every available series of experiments explained, critizised and 

 debated. All the literature was demonstrated.
