HENRY AUGUSTUS ROWLAND* 



In reviewing the scientific work of Pro- 

 fessor Rowland one is most impressed by its 

 originalitj^ In quantity, as measured by 

 printed page or catalogue of titles, it has 

 been exceeded by many of bis contempora- 

 ries ; in quality it is equaled by that of 

 only a very, very small group. The entire 

 collection of his important papers does not 

 exceed thirty or forty in number and his 

 unimportant papers were few. When, at 

 the unprecedentedly early age of thirty- 

 three years, he was elected to membership 

 in the ISTational Academy of Sciences, the 

 list of his published contributions to science 

 did not contain over a dozen titles, but any 

 one of not less than a half dozen of these, 

 including what may properly be called his 

 very first original investigation, was of such 

 quality as to fully entitle him to the dis- 

 tinction then conferred. 



Fortunately for him, and for science as 

 well, he lived during a period of almost un- 

 paralleled intellectual activity', and his work 

 was done during the last quarter of that 

 century to which we shall long turn with 

 admiration and wonder. During these 

 twenty- five years the number of industrious 

 cultivators of his own favorite field increased 

 enormously, due in large measure to the
