Reviews — Huxleijs Physiography. 563 



Among the figures eliminated from tlie Guide, we miss the 

 picture of the ' Musk-ox,' and the molar teeth of the Indian and 

 African elephants (useful for comparison) ; these are probably 

 excluded as living forms, but by the time a new edition is called 

 for we may see the whole of the recent and fossil mammalia and 

 birds amalgamated in one Guide. Signs are not wanting of what 

 Sir Henry Howorth, writing to the Times, described as the coming 

 fusion of the Louvre and the Luxembourg Galleries.

IT was in 1877 that Huxley's " Physiography " was introduced to 

 the public, and to a certain extent it revolutionized, as was the 

 aim of the author, the old method of teaching Physical Geography. 

 He sought to convey scientific conceptions by an appeal to observa- 

 tion ; to create interest in the study of ' Earth-knowledge ' by 

 commencing with the local geography, " until step by step the 

 conviction dawns upon the learner that, to attain to even an 

 elementary conception of what goes on in his parish, he must know 

 something about the universe." Thus " the knowledge of the child 

 should, of set purpose, be made to grow in the same manner as that 

 of the human race has spontaneously grown." 



The original edition of Huxley's book owed much, as the author 

 cordially acknowledged, to the editorial care of Mr. F. W. Rudler. 

 The work became at once popular in the best sense of the term, 

 a third edition was issued in 1880, and it has continued to hold its 

 place with comparatively little alteration until the appearance of the 

 present work. The progress of science during the past quarter of 

 a century has, however, made necessary many additions and modi- 

 fications in detail, while here and there alteration in plan has been 

 deemed desirable. 



The most prominent change is in the omission of the special 

 reference to the Thames and its basin, which Huxley had taken for 

 his ' text ' ; instead, the central idea has been transferred to any 

 river basin. This difference in treatment is marked when we com- 

 pare the index of the present volume with that of Huxley's third 

 edition. In the latter there are more than sixty references to the 

 Thames and its basin. In the present index the Thames is not 

 recorded. Considering the interest of the subject, a little more space 

 might have been given to the "Development of a drainage area," as 

 but scant justice can be accorded in a page of print to the views 

 enunciated by Professor W. M. Davis ; and his nomenclature of 

 rivers is not even mentioned. 



A conspicuous feature in the new work consists in the number of 

 admirable pictorial and other illustrations, of which six only appeared 

 in the old editions ; and it is satisfactory to find that while the work
