A.NTS, BEES, AND WASPS. A Record of Observations on tha 

 Habits of the Social Hymenoptera. By Sir JOHN LCBBOCK, Bart., 

 M. P., F. R. S., etc., author of " Origin of Civilization, and the Primi- 

 tive Condition of Man," etc., etc. With Colored Plates. 12rao. 

 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 Sir John's mode of experiment differs torn 

 those of Huber, Forel, McCook, and others, is that he fans 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 1874. 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 bren 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 Atfienceum.

MYTH AND SCIENCE. By TITO VIGNOLI. 12mo. Cloth, $1.50.

 from and conquered myth is extremely well wrought out, and is probably in essentials 

 correct." Saturday tieview.

 title would indicate. The learning, the acuteness, the strong reasoning power, and the 

 scientific spirit of the author, command admiration." New York Christian Advocate.

 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."

 history of man's development." New York World.
