He attended the 1841 meeting of the Asso- 

 ciation of American Geologists and Natur- 

 alists and read a paper of capital impor- 

 tance upon the slates of AA'"aterville, Maine, 

 in which he discussed the markings upon 

 the slates and indicated their organic origin, 

 which he regarded as proving their great 

 age. He was present also at the third 

 meeting and took a prominent part in the 

 discussion of the ' drift ' so that he was ap- 

 pointed member of the committee to pre- 

 pare a report upon that subject for the next 

 meeting. He was elected secretary of the 

 Association for 1843 and, with Benjamin 

 Silliman, Jr., served in the same ofl&ce for 

 1844. His duties at Dartmouth were ex- 

 acting, so that for many years he published 

 few extended papers, but he made many 

 brief communications to societies, all of 

 which were characterized by keen discrimi- 

 nation and manjj- of them were important 

 contributions. 



Doctor Hubbard joined this Academy in 

 1874 and at once became so active that 

 when Mr. Browne, who had been Record- 

 ing Secretary from 1839, resigned in 1875, 

 Professor Hubbard was chosen as his suc- 

 cessor. He retained this office until 1885, 

 when he became Vice-President. At the 

 death of Doctor N"ewberry in 1892, he was 

 made President, but he served for only one 

 term, declining re-election because of his 

 advanced years. From 1874 until 1893 he 

 rarely failed to attend the meetings, when 

 in the city, and he alwaj's presented some- 

 thing of interest bearing upon matters under 

 consideration. His manner was courteous 

 to the last degree and he understood well 

 how to discuss without disputing. 



Professor Hubbard's individuality was 

 very decided ; though so gentle and con- 

 siderate in his manner, he always held posi- 

 tive opinions and, when necessary, did not 

 hesitate to express them. His shrewd com- 

 mon sense made him a good counsel and 

 his advice was sought in many directions. 



He was a member of the New Hampshire 

 Legislature in 1863-4, but one year's ex- 

 perience in that kind of work sufficed and 

 he declined to be a candidate for re-elec- 

 tion. His quiet humor and his store of 

 reminiscences made him a delightful com- 

 panion. He retained his mental vigor to 

 the last and only two months ago he pub- 

 lished an article correcting errors in a re- 

 cently published work. When ninety 

 years old, he attended the New York meet- 

 ing of the Geological Society of America 

 and remained throughout an afternoon 

 listening to severely abstract papers, with 

 as much interest, apparently, as though he 

 were just beginning his work. 



Professor Hubbard was almost the last 

 link binding our time with that of the 

 early geologists. Hall and Dana died 

 within the last half decade and there re- 

 main only Boye and Lesley of those who 

 attended the earlier meetings of the Asso- 

 ciation of American Geologists. He passed 

 away in a ripe old age, his life full of good 

 works and his name absolutely unstained. 

 This Academy owes him much, and here 

 his name should be cherished.

The purpose of the GifFord Lectures at the 

 four Scottish universities is now understood 

 pretty well even in foreign countries. The 

 Deed of Gift defines it as the " Promoting, Ad- 

 vancing, Teaching and Diffusing the study of 

 Natural Theology, in the widest sense of that 

 term"; and directs the "lecturers to treat their 

 subject as a strictly natural science, without
