nately, for the most part in the briefest possible form, and the results of many 

 of his researches are to be found only in the manuals he published. As an 

 author Professor Peirce was highly esteemed upon both sides of the Atlantic ; 

 his work on analytical mechanics, which appeared in 1857, being regarded 

 then, even in Germany, as the best of its kind. ... As a lecturer Professor 

 Peirce was highly esteemed in both scientific and popular circles. It is rela- 

 ted that in 1843, ^Y a sei "i es of popular lectures on astronomy, he so excited 

 the public interest that the necessary funds were supplied for, erecting an 

 observatory at Harvard. A remarkable series of lectures on "Ideality in 

 Science," delivered by him in 1879 before the Lowell Institute in Boston, 

 attracted the general attention of American thinkers, on account of the 

 thoughtful consideration of the vexed question of science and religion. 



Much of Professor Peirce's activity was absorbed by his duties as the head 

 of the American Coast Survey, a position in which he succeeded Professor 

 Bache. He brought to this work the same degree of zeal and ability which 

 were so brilliantly evidenced by his predecessor, and constantly maintained 

 the well-earned reputation of the Coast Survey among the hydrographic 

 efforts of our day. Professor Peirce was one of the founders of the Ameri- 

 can National Academy of Sciences. In 1853 he presided over the American 

 Association for the Advancement of Science. .

 in 1869, an d for three years gave great attention to the Department of Edu- 

 cation, of which he was chairman from 1869 to 1872. At the time, in 1872-73, 

 when the practical discontinuance of the Association was favored by many 

 members, by reason of the difficulties attending its work, Professor Peirce 

 was one of those who most earnestly urged its continuance; and it was 

 mainly owing to his remarks and. those of Professor Agassiz, at one or two 

 public meetings in Boston, that the Association remained in activity during 

 the years of panic and political change that followed in the re-election of 

 Gen. Grant in 1872. He supported the course taken by the Association in 

 1874, in favor of " honest money," and in that year, for the first time, read a
