viii PREFACE 



a likeness of its subject, but of portraits of some of 

 his more notable comrades. I have accordingly added 

 likenesses of a dozen of his geological associates 

 whose names and work are well known. These have 

 been taken as far as possible from early photographs, 

 so as to picture the men as they looked when they 

 were actively engaged with Ramsay in geological 

 work. But in some cases when no early likeness 

 was available, or where the photographs had become 

 too faded for reproduction, later portraits have been 

 chosen.
