Guide to the specimens of the horse family (Equidae), R. Lydekkek (Lon- 

 don; Oovt., 1907, pp. 42, pis. 15). — This contains an outline of the evolution of 

 the horse and an account of the specimens in the British Museum, which repre- 

 sent different types of living and extinct relatives of the horse. 



On the science of hippolog-y, E. Nicolas (Rev. G6n. Med. V^t., IJf (1909), No. 

 159-160, pp. 129-168, figs. 3). — The author explains the need for more exact 

 information relating to the characteristics of horses, and outlines a method of 

 procedure which should be adopted in purchasing horses to be used in the 

 French army. Measurements and various tests should be made periodically, 

 from the time of purchase until the death of the animal. Accurate records 

 of the form, physiological characters, adaptability for different kinds of work, 

 and a post-mortem examination would eventually supply data for an exact 

 science of liippology. 



The Nellore cattle, F. C. Geaehart (Pliilippinc Agr. Rev. [English Ed.], 2 

 (1909), Xo. 7, pp. 373-375, pi. 1). — A brief account of a shipment of Xellore 

 cattle from India to the Thilippine Islands. It is thought that these cattle are 

 superior to any of the indigenous breeds. Up to the present time European 

 breeds have not proved to be of any value under natural range conditions in 

 the Orient. 



Rations for fattening swine, B. E. Carmichael (Ohio 8ta. Bui. 209, pp. 71- 

 89). — Young growing animals were used in all the experiments.
