From 1863 till 1867 he was vice-president of the city council and member of the school-board. While holding these offices he was invited by Louis Agassiz to come to Cambridge as assistant in entomology at the Museum of comparative zoölogy, and in 1870 was made professor of that science at Harvard. In 1863 he received the honorary degree of Ph.
