THE LIFE AND WORK OF DR. GOULD. 



Somewhat more than a week has passed 

 since the sods were placed over the honored 

 grave of Dr. Gould, yet even in the busy 

 haste of our American life there are many 

 who will welcome an appreciative account 

 of the life and achievements of this eminent 

 astronomer. So many notices of him were 

 printed in the daily journals, immediately 

 after the community was apprized of its sad 

 loss, that it is unnecessary here to recount 

 the details of his work. But it may be of 

 service to give, in right perspective, a just 

 idea of the magnitude and character of his 

 contributions to astronomy, to speak of the 

 purpose and importance of what he accom- 

 plished for science, and of the nature of his 

 strong personal influence in its advance- 

 ment. 



Considered apart from the great things 

 he accomplished, the first thing that strikes 

 us about his career is the intimate way in 

 which it is bound up with the history of his 

 beloved science on both sides of the Atlan- 

 tic, and the unique position he held, as il- 

 lustrated by the number and extent of his 

 personal alliances. It is scarcely possible 

 to realize that he was the friend of von 

 Humboldt, then in his 77th year ; that it 

 was due to the friendly interest of this great 

 man, indeed, that he became the pupil, 

 friend and intimate in the household of the 

 great master of modern astronomy, Gauss, 

 then in his 70th year; that he was the
