carriages, he says that even greater endurance is shown by certain wild 

 animals that are akin to Dogs. Thus the Wolf can run between fifty 

 and sixty miles in one night, and an Arctic Fox can do quite as well, 

 if not better. Nansen met one of these Foxes on the ice at a point 

 more than seventy miles north-west of the Sanikow territory, which 

 is 480 miles from the Asiatic coast. Eskimo and Siberian Dogs can 

 travel forty-five miles on the ice in five hours, and there is one ease 

 on record in which a team of Eskimo Dogs travelled six and one-half 

 miles in twenty-eight minutes. According to M. Dusolier, the speed 

 of shepherd Dogs and hunting Dogs ranges from ten to fifteen yards 

 a second. Foxhounds are extraordinarily swift, as is proved by the 

 fact that a Dog of this breed once beat a thoroughbred horse, covering 

 four miles in six and one-half minutes, which was at the rate of 

 nearly eighteen yards a second. Greyhounds are the swiftest of all 

 four-footed creatures, and their speed may be regarded as equal to 

 that of carrier Pigeons. English Greyhounds, which are carefully 

 selected, and which are used for coursing in Nebraska and other 

 States, are able to cover at full gallop a space between eighteen and 

 twenty-three yards every second. 



The Council of the London Natural History Society invites any

Mr. E. G. Boulenger, F.Z.S., who has charge of the unrivalled 

 collection of lower vertebrates in the Zoological Society's Gardens 

 in Begent's Park has just produced a monograph on ' Beptiles and 

 Batrachians,' unique in the fact that it is a comprehensive treatise 

 devoted entirely to the study of this particular branch of Natural 

 History. The author gives a complete account of the general classi- 

 fication of the groups dealt with, and a detailed description of the 

 commoner and more interesting types : he also deals very fully with 

 the habits of the animals in captivity, for observing which he has 

 had special opportunities, and much that is included is the result of 

 his direct observation, and has not previously been recorded. 



The book is illustrated by two hundred photographs, mostly 

 from living specimens, and by numerous figures in the text. 



Messrs. J. M. Dent & Sons issue the book.
