lectures, racy with humour and crowded with 

 adventure, were always counted among- the prin- 

 cipal features of the session's programme. 



We owe to Tempest Anderson also several im- 

 portant contributions to the literature of volcanic 

 geology, including a report to the Royal Society on 

 the West Indian eruptions of 1902 and papers on 

 the eruptions of Savaii and of Guatemala. But he 

 was ever more ready with the camera than with 

 the pen, and it is well known to his friends that he 

 had an enormous number of negatives of active 

 and extinct volcanoes, and his mind was richly 

 stored with facts concerning them. He was a 



Journal. The photographs and descriptions 

 take us over a very large field. Vesuvius, 

 Etna, the Liparis, St. Vincent, Martinique, 

 Mexico, Guatemala, Savaii, Hawaii, Java, 

 Krakatau, and Luzon receive illustration in turn. 

 Prof. Bonney's notes contain many particu- 

 lars extracted from Tempest Anderson's field 

 notes, and the book is full of interest, not only to 

 the professed man of science, but also to all who 

 admire beautiful or striking scenery and desire to 

 understand its origin. 



Most of the photographs are very well repro- 

 duced, though they are not all of equal merit, but

true enthusiast. When news arrived of an im- 

 portant eruption in Java or Savaii it was not long 

 before Tempest Anderson had completed his 

 arrangements to visit the spot and get some good 

 photographs. No difficulties, dangers, ill-health, 

 or expense daunted him ; and though neither 

 young nor very robust, he always succeeded. 



This memorial volume has been edited by Prof. 

 Bonney, one of his oldest friends, whom he always 

 recognised as his guide and master in his investi- 

 gations. It appears as the second part of a 

 volume with the same title issued in 1903, and 

 contains eighty-one photographs with descriptive 

 text. A short biographical notice by Mr. G. Yeld 

 is reprinted, with some additions, from the Alpine

this can be understood by anyone who knows the 

 difficulty of getting good negatives on tropical 

 expeditions and surrounded by the fumes of active 

 volcanoes. The. most interesting subjects are 

 Krakatau as it was in 191 3, Tarawera in 1913, 

 Savaii, and (best of all in our opinion) the terrible 

 volcanoes of Java. Some of the views taken in 

 earlier years have been already published, and 

 where so much was available we question whether 

 it was advisable to reproduce them. The text is 

 very clear and admirably suited to the pictures, 

 but we would take exception to the explanation 

 of the "bread-crust" bombs on p. 42. The 

 Clacked crust is due, not to the contraction of the 

 crust or the interior, but to the expansion of the
