MESSMATES : 



A Book of Strange Companionships 



By EDWARD STEP. F.L.S. 



Author of "The Romance of Wild Flowers," " Shell Life," etc. 



With 55 illustrations _^om photographs on art paper. 



A popular account of the remarkable partnerships habitually 

 set up between animals totally unrelated, and even between 

 animals and plants. These associations, to which Science 

 appHes the terms Commensalism and Symbiosis, are quite 

 different from Parasitism, with which many of them were 

 formerly confused, as they are based on the principles of mutual 

 aid and advantage ; whilst Parasitism implies advantage to one 

 side and loss to the other. The stories told are of absorbing 

 interest, and the author has told them for the general reader, 

 avoiding; all technicalities. The book will be fully illustrated 

 by photographs and drawings. 



THE COURTSHIP OF 

 ANIMALS 



By W. P. PYCRAFT. A.L.S.. F.Z.S. 



With numeroiis illustrations on art paper. 



The aim of this book is to bring together what will surely 

 prove to be a most astounding collection of facts in regard to 

 the Courtship of Animals of all kinds, from Apes to Ants. It 

 will describe the sanguinary conflicts which obtain when mates 

 are only won by battle, as m the case of deer and sea-lions, and 

 other beasts ; and the no less bloody, and often fatal battles 

 fought by birds whose legs and wings are armed by_ fearsome 

 spurs for this purpose. But quite as interesting will be the 

 survey of the methods which more properly fulfil the meaning 

 of courtship — strange dances, love flights and musical rivalry, 

 and the display of gorgeous vestments such as are furnished 

 by the birds.
