570 WILLIAM HOLMES CHAMBERS BARTLETT. 



President, the lion. Charles F. Adams, was too seriously affected in 

 health to fulfil that duty. Impossible as it was in so brief a time for 

 the orator to do justice to himself or the occasion, he gave an eminently 

 graceful and ai)propriate discourse. 



Mr. Winthrop was twice married, and three children survive him. 

 The memory of his character and services is among the precious 

 possessions of this century in Massachusetts.

WILLIAM HOLMES CHAMBERS BARTLETT. 



William Holmes Chambers Bartlett, for many years Pro- 

 lessor of Natural and Experimental Philosophy in the Military Acad- 

 emy at West Point, contributed as much as any man to impress 

 upon that institution its well known character. As a scientist, he 

 was one of the tlrst to base a system of physics on the principle of 

 the conservation of energy ; as a teacher, he was so clear and logical 

 that he made the most complicated laws of physics and astronomy 

 embraced in his course of instruction appear to be self-evident truths. 

 His genial manner and personal interest in his pupils will ever be 

 remembered with gratitude, and his magnetic influence helped to unite 

 the officers of the army and attach them to the Union at a time when 

 so many were tempted to join their native States. 



He was born in Lancaster, Pennsylvania, in September, 1804, but his 

 parents moved to St. Louis, Missouri, while he was yet an infant. He 

 was appointed a Cadet at the Military Academy in 1822, graduated at 

 the head of his class in 1826, and promoted to the rank of Second Lieu- 

 tenant of Engineers. He served at the Military Academy as Assistant 

 Professor of Engineering from 1827 to 1829 ; as Assistant Engineer 

 in the construction of Fortress Monroe, Virginia, in 1828, and of 

 Fort Adams, Newport, Rhode Island, from 1829 to 1832; as Assist- 

 ant to the Chief of Engineers at Washington, from 1832 to 1834; as 

 Acting Professor of Natural and Experimental Philosophy from 1834 

 to 1836; and as full Professor from 1836 to 1871, when, on his 

 own application, he was retired from the active list for forty years of 

 continuous service. Since his retirement he has been Actuary of the 

 ]\Iutual Life Insurance Company of New York. He died at Yonkers, 

 New York. Februarv 11, 1893.
