 Botany is less recent, but very suggestive. All four books are 

 profusely illustrated.

The first three of the books above mentioned are devoted to 

 experiments in vegetable physiology. Detmer's is the best for 

 those who can read German. Strasburger's book is devoted to 

 vegetable histology and is excellent, though the translation by 

 Hillhouse (of Strasburger's larger work) is less satisfactory than the 

 Kleines Botanisches Practicum. Spalding's Introduction is not whoUy 

 a laboratoiy manual, though largely so. It supplies admirable 

 directions for getting acquainted with plant life and structure at 

 first hand. Huxley's Biology is partly devoted to animals, partly to 

 plants. It gives excellent directions for the laboratory study of some 

 of the lower forms of plant life.
