chronologically indicate to some extent the 

 development, progress, scope and character of 

 his life work. They embrace sjibjects pertain- 

 ing to geology, paleontology, zoology, botany, 

 anthropology, local history, medicine and do- 

 mestic science. Besides these writings of 

 permanent importance there have been many 

 of transient interest, for Dr. White began 

 writing for publication as early as 1847. 



The prosecution of much of his geological 

 work was of the nature of pioneer exploration, 

 and was extended into most of the states and 

 territories west of the Mississippi. He twice 

 traveled extensively in Europe, the second 

 time accompanied by his wife, when they ex- 

 tended their journeyings into Egypt and 

 Palestine. 



His correspondence' with scientists and 

 other noted persons both in our own country 

 and abroad was extensive. Many of the letters 

 thus received are preserved in the State His- 

 torical Department of Iowa, at Des Moines, 

 where also his diplomas, testimonials, com- 

 missions, etc., are preserved. He made that 

 disposition of those papers because he grew 

 up to citizenship in Iowa, and always con- 

 tinued to regard himself as a citizen of that 

 state.
