Ants, Bees, and Wasps. 



A Record of Observations on the Habits of the Social Ilymcnoptera. By 

 Sir Joii-S Lubbock, Bart., M. P., F. R. S., etc., author of " Origin of Civiliza- 

 tion, and the Primitive Condition of Slan," etc., etc. With Colored Plates. 

 12mo, cloth, $2.00. 



"This volame contains the record of various experiments made with ants, bees, and wasps dur- 

 in^r the last ten years, with a view to test their mental condition and j)Owei-s of sense. The prin- 

 cipal point in which ?ir John's mode of experiment dift'ers from thost.- of lluber. P^ord. McCook, 

 and others, is that he has carefully watched and marked particular insects, and has had their 

 nests under observation for Ions' periods — one of his ants' nests havinj,' been imder c<mstatit in- 

 spection ever since 1S74. His observations are made principally uj)on ants because they show 

 more power and flexibihty of mind; and the value of his studies is that they belong to the de- 

 partment of original research." 



" We have no hesitation in saying that the author has presented \is with the most valuahie 

 series of observations on a special subject that has ever been produced, charuiingly written, full of 

 logical deductions, and, when we consider his multitudinous engagements, a remarkable illus- 

 tration of economy of time. As a contribution to insect psychology, it will be long before this 

 boot finds a parallel." — London Athenceum.

Myth and Science. 



By Tito Yignoli. 12mo, cloth, price, $1.50. 



" His book is ingenious ; . . . his theory of how science gradually differentiated from and con- 

 quered myth is extremely well wrought out, and is probably in essentials correct." — Saturduy 

 xieview.

 indicate. The learning, the acuteness, the strong reasoning power, and the scientific spirit of the 

 author, command admiration."— iVeiw Yu?'k Chiistian Advocate. 



" An attempt made. Avith 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.''' —p'hiladelphia JVorth Ainerican. 



" It 13 a curious if not startling contribution both to psychology and to the em-ly history ol 

 man's development." — New York World.
