APPENDIX D. 259 
summary of botany in a moderate-sized octavo volume. Behrens’s” 
Botany is less recent, but very suggestive. All four books are 
profusély 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 wholly 
a laboratory 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.
