THIS book covers the college entrance requirements in 

 botany, providing a course in which a careful selection 

 and a judicious arrangement of matter is combined with 

 great simplicity and definiteness in presentation. 

 ^ The course offers a series of laboratory exercises in the 

 morphology and physiology of phanerogams ; directibns for a 

 practical study of typical cryptogams, representing the chief 

 groups from the lowest to the highest ; and a substantial 

 body of information regarding the forms, activities, and re- 

 lationships of plants and supplementing the laboratory studies. 

 ^ The work begins with the study of phanerogams, taking 

 up in the order the seed, bud, root, stem, leaf, flower, and 

 fruit, and closing with a brief but sufficient treatment of 

 cryptogams. Each of the main topics is introduced by a 

 chapter of laboratory work, followed by a descriptive chapter. 

 Morphology is treated from the standpoint of physiology and 

 ecology. A chapter on minute structure includes a discussion 

 of the cell, while another chapter recapitulates and simplifies 

 the physiological points previously brought out. 

 ^ The limitations of the pupil, and the restrictions of high 

 school laboratories, have been kept constantly in mind. The 

 treatment is elementary, yet accurate ; and the indicated 

 laboratory work is simple, but so designed as to bring out 

 fundamental and typical truths. The hand lens is assumed 

 to be the chief working instrument, yet provision is made for 

 the use of the compound microscope where it is available.
