A popular work, in part a compilation, but including much interesting 
original matter.. The term “ants” is used in its widest possible 
extension, to include Formicidce, Dorylidaz , Mutillidce , Thynnidce , and 
Termites. The writer (ch. iii.) argues that Sir J. Lubbock’s obser- 
vations on the vision of ants are open to an alternative explanation, 
and thinks that ants may possibly shun the ultra-violet rays of the 
spectrum rather on account of their chemical action than of their 
colour. On p. 50, a curious instance of the beneficial effects of formic 
acid is related, which may not be unworthy the attention of medical 
men. F. Smith estimated the probable number of species of ants at 
about 3000 (pp. 87 & 88). Observations on Aphides , and other myr- 
mecophilous insects, likewise occur. The illustrations are very fairly 
good.
