8 Editor's Foreword 



volume should appeal not only to the oil geophysicists and geologists but 

 to everyone interested in modern developments in geophysical methodology. 

 Since the translation of Soviet scientific hterature is as yet in a pioneering 

 stage it is, perhaps, not inappropriate to add a few remarks of a purely Hnguis- 

 tic nature. The relatively prolonged isolation of Russian scientists from 

 their western colleagues has led to differences in terminology. For instance, 

 the Russian term equatorialnyi sond does not mean an equatorial sonde, 

 but probes with a quadrilateral arrangement, while the word podniatie in 

 various contexts impHes an elevation, a culmination or an upfold. In the 

 present volume, where necessary, the Russian usage is indicated and it is 

 hoped that such editorial remarks will be of use to the translators of scien- 

 tific Russian. Responsibihty for these remarks rests with the editor, but in 

 certain instances Professor R. M. Shackleton and Dr. C. D. V. Wilson of 

 the University of Liverpool were consulted and made suggestions, for which 

 the editor wishes to express his gratitude.
