52 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



the instruments and their capacity. My intention is to observe right 

 ascensions of certain stars with the present Transit, and, if practica- 

 ble, to get a better Meridian Instrument and pursue the observation 

 of the zone 35 to 40, undertaken at Chicago. 



My leisure is rather limited. I am professor of physics and as- 

 tronomy, and am printing two volumes: (1) Observations of right 

 ascension, about 15,000 in number, made at Cambridge in 1862-65 

 by several observers (about half my own), on a plan arranged be- 

 tween Professor G-. P. Bond and myself. The stars are largely those 

 near the pole, and contribute to my general plan of work. (2) A 

 compiled catalogue of 2018 latitude stars, for Lieut. Wheeler, U.S.E. 

 Modern authorities are utilized, including many scattered series by 

 Bessel, Gauss, Argelander, Struve, and others, which have mostly 

 escaped notice because used in special memoirs on latitude. My 

 last publications, w r ith one exception, treat of the solar motion as 

 connected with the stars 1 proper motions and distances; and the 

 observations of the next year will bear on this subject. 



My present working list contains nearly 400 stars. These are such 

 as occur in the two books above mentioned and need reobservation ; 

 mostly those which exhibit a decided proper motion not yet deter- 

 mined with accuracy ; in many cases wrongly given elsewhere.
