A Catalogue of the Declinations of 532 Stars culminating near the Zenith of the 
Observatory of Harvard College, Cambridge. 
By T. H. SAFFORD. 
(Communicated September 11, 1860, by G. P. Bonn.) 
Tue Catalogue here communicated was originally prepared at the Observatory of 
Harvard College, at the request of Captain George G. Meade, of the United States To- 
pographical Engineers, for the use of the Survey of the North and Northwest Lakes, in 
the determinations of latitudes with the zenith telescope, according to the method 
proposed by Talcott. ‘The method requires for its successful application the combi- 
nation of pairs of stairs distant generally less than 10^ from the zenith of the place 
of observation, and having accurately determined positions. The present collection has 
been the result of a careful discussion of the positions of the stars included, as given 
by the best existing authorities,* and is intended to facilitate the determinations of 
latitudes at stations near the northern boundary of the United States.
