ANTS, BEES, AND WASPS. A Eecord of Observations on the Habits of the 
Social Hymenoptera. By Sir JOHN LUBBOCK, Bart., M. P., F. K. 8., etc., author 
of " Origin of Civilization, and the Primitive Condition of Man,' 1 etc., etc. With 
Colored Plates. 12mo, cloth, $2.00. 
"This volume contains the record of various experiments made with ants, bees, and 
wasps during the last ten years, with a view to test their mental condition and powers 
of sense. The principal point in which !?ir John's mode of experiment differs from 
those of Iluber, Forel, McCook, and others, is that he has carefully watched and 
marked particular insects, and has had their nests under observation for long periods 
one of his ants' nests having been under constant inspection ever since 1814. His 
observations are made principally upon ants because they show more power and flexi- 
bility of mind ; and the value of his studies is that they belong to the department of 
original research." 
" We have no hesitation in saying that the author has presented us with the most 
valuable series of observations on a special subject that has ever been produced, charm- 
ingly written, full of logical deductions, and, when we consider his multitudinous en- 
gagements, a remarkable illustration of economy of time. As a contribution to insect 
psychology, it will be long before this book finds a parallel." London Athenaeum.

MYTH AND SCIENCE. By TITO VIGMOLI. [12mo, cloth, price, $1.50. 
" His book is ingenious ; ... his theory of how science gradually differen- 
tiated from and conquered myth is extremely well wrought out, and is probably in 
essentials correct." Saturday Review. 
"The book is a strong one, and far more interesting to the general reader than its 
title would indicate. The learning, the acuteness, the strong reasoning power, and the 
scientific spirit of the author, command admiration." New York Christian Advocate. 
"An attempt made, with much ability and no small measure of success, to trace the 
origin and development of the myth. The author has pursued his inquiry with much 
patience and ingenuity, and has produced a very readable and luminous treatise." 
Philadelphia, North American. 
" It is a curious if not startling contribution both to psychology and to the early 
history of man's development." New York World.
