Press Notices 



" The papers which Mr Buchanan republishes in this volume are 

 specially interesting as placing on authoritative and permanent record 

 the original papers of a worker who was to a very great extent a pioneer 

 in a new subject. However great are or may be the amplifications and 

 modifications of the results obtained from the great voyage of H.M.S. 

 Challenger, it cannot be disputed that they laid the foundations of 

 physical oceanography, and that the foundations were well and truly 

 laid. Upon the chemist and physicist of the expedition there fell the 

 task not only of exploring unknown seas, but of devising means of doing 

 so ; and the most important papers in this volume are probably those 

 discussing the relation of specific gravity to salinity in sea-water, 

 the formation of sea-water ice, and instrumental methods generally, 

 or describing the laboratory experiences on board the Challenger, or 

 apparatus employed in deep-sea investigation up to the year 1881. 

 Mr Buchanan's work has been discussed and built upon by later workers 

 of all nationalities, and we may be allowed to offer our congratulations 

 to a veteran in the field of research upon the appearance of this book of 

 collected papers." Geographical Journal 



" The numerous expeditions which have explored the depths of the 

 sea since the voyage of H.M.S. Challenger during the years 1873-76 



have added much to our detailed knowledge but the great pioneer 



voyage remains the only one which has surveyed the whole world of 

 waters, and it is remarkable how little the work of more recent years... 

 has modified the broad outlines of the Challenger results. It is of 

 fundamental importance to the history of oceanography that the record 

 of these early investigations should be made accessible once for all by 

 the best authorities ; those authorities, to wit, to whom the researches 

 themselves were originally due.. ..It is therefore a matter for much 

 satisfaction that this has now been done, in so far as the physical and 

 chemical work is concerned, by the chemist and physicist of the expedi- 

 tion himself.. ..We welcome this volume of reprints of his original papers, 

 both for historical reasons and for the permanent value of the results 

 obtained." Nature
