ANNALS OF THE ACADEMY 65 



tion ordered to be included with the report of the President 

 for that year. It was not published there, however, but in the 

 Memoirs of the Academy. 52 A resolution was also adopted by 

 the Academy thanking the Secretary of the Navy for the aid 

 rendered by the Navy Department, and also Captain Carpenter 

 and the other officers of the Hartford for " the energy and 

 personal interest with which they co-operated in the work." 



We read in the annual report of the Secretary of the Navy 

 for 1883 that "the Hartford, before she became the flagship 

 [of the Pacific Station], made a cruise to Caroline Island, carry- 

 ing a party of observers of the solar eclipse, sent by the National 

 Academy of Sciences "; 53 also the following: 



"Hartford: Arrived at Callao from the United States January n, 1883. 

 Proceeded to Caroline Island with a party of observers of solar eclipse in May 

 last. Returned to Callao via Honolulu; arrived at Callao August i8." 54 



Through the death of Joseph Henry in 1878, the National 

 Academy of Sciences became concerned with the Tyndall trust 

 fund. This fund, which amounted to about $13,0x30, was estab- 

 lished by John Tyndall from the proceeds of his lectures in 

 America in 1872 and 1873. Having been invited by friends to 

 lecture in this country, he decided to do so, with the idea of 

 bringing pecuniary aid to the city of Chicago which, as is well 

 known, was devastated by fire in the fall of 1871. On arriving in 

 America, however, he found that the city had already received 

 such great contributions of money that the amount he could com- 

 mand would be insignificant in that connection. He turned his 

 donation, therefore, in the direction of establishing a trust fund 

 to enable American students of physics to study at the German 

 universities. He designated Professor Joseph Henry, Dr. E. L. 

 Youmans, and General Hector Tyndale, a kinsman, as trustees 

 of the fund, with the proviso that vacancies on the board oc- 

 curring through death or otherwise should be filled by the
