The relations existing between ants and numerous vegetable 

 species has received much attention of late in the studies of sev- 

 eral biologists, notably of the younger Schimper and Delpino. 

 Taking this topic as the text of an address as the retiring presi- 

 dent of the Cambridge Entomological Club, Professor Trelease 

 remarks on the present state of knowledge of the very interesting 

 subject, and the views and hypotheses of the several observers.

 Outlines of Lessons in Botany, /. Jane H. Newell. (Ginn 



and Co., Boston, 1889, pp. 140). 



Miss Newell's attractive little volume in its completed form 

 more than fulfils the promise of its first chapters, which were is- 

 sued separately as pamphlets. The plan is not only perfect- 

 ly practicable and the method of treatment suggestive, but it is 

 also calculated to lead to a knowledge of more complex process- 

 es through a series of simple experiments which any child could 

 perform. The illustrations also are excellent and attractive, evi- 

 dently studied from nature, recording stages of common things 

 in a way to make both teacher and pupil wish to see for them-
