REVIEWS AND NOTICES OF BOOKS. 



Le Monde Social. des Fourmis du Globe compare a celui de V Homme. 

 By Dr. Auguste Forel, Geneva, Librairie Kundig, Editeur. Tome lier, 

 1921. Pp. i.-xiv. and 192 ; 2 coloured plates, 1 black and white plate, 

 and 30 figures in the text. 



The first volume of this interesting and comprehensive work on 

 the ants of the World has been sent to us to review. The book will be 

 completed in five volumes, and we advise all students, not only of 

 Hymenoptera, but of Entomology in general, who can read the French 

 language to obtain it as soon as possible. The price 10 francs a 

 volume (which is very moderate especially taking into consideration 

 the great cost of publication everywhere at the present time) should 

 bring the work within the reach of everyone. 



Volume I. deals with the genesis of ants, their anatomy, general 

 classification and geographical distribution. 



Chapter I. : Phylogeny (evolution of the species of ants of the 

 geological epochs up to the present day). 



Chapter II. : Ontogeny (evolution from the egg, and larva to the 

 adult state). Polymorphism (the three or four kinds of individual 

 adults). 



Chapter HI. : Exterior anatomy (skin, hairs, sculpture, limbs). 



Chapter IV. : Interior anatomy (digestive canal, nervous system, 

 brain, glands, muscles, etc.). 



Chapter V. : General summary of Classification. 



Chapter VI. : Geographical Distribution. Migrations ancient and 

 modern, local faunas. 



Chapter VII. : Fossil Ants. 



The beautiful coloured plates as well as all the other illustrations 

 both original and reproductions are by Mons. E. W. Heinrich and 

 deserve great praise. 



The arrangement of the figures in the text is not good, and gives 

 considerable trouble to the student. The figures are not in order but 

 dotted about all over the book ; for example— Fig. 20 is on page 115, 

 but Fig. 22 is on page 49 ; Fig. 25 on page 43, etc. ! Then in the 

 text when one is told to see Fig. " so and so," one has to turn to the 

 index and find out on which page it is, and then turn for that page, 

 and lose one's place, and the sequence of one's thoughts, etc. 



It is not our purpose here to discuss the whole work in detail, nor 

 would the space at our disposal allow of it. We can only touch on a 

 very few points ; but the reader may rest assured that every problem 

 concerning ants is mentioned and expounded by the author. 



In the preface the author gives a short account of his earliest 

 experiences with ants at the village of Lonay pres de Morges, where 

 he spent the first eight years of his life. He also records that at the 

 age of eleven he was given Pierre Huber's work on the habits of ants,
