The stars consisted mainly of stars used in the Army surveys for observations with the zenith telescope, many stars in the lists of the Coast Survey, and many of Lacaille's stars which had mostly been observed by Lacaille only, and for observing which our Observatory was favorably situated. During these years, Mr. James Ferguson, who so faithfully labored for so many years with the Equatorial, was making constant demands upon me (Yarnall) for observations of comparison stars for the objects observed by him; and this will account for the great number of small stars in the Catalogue.

Excerpt from Catalogue of Stars Observed at the United States Naval Observatory During the Years 1845 to 1871 When the time came for putting these observations in the form of a Catalogue, the number of stars having greatly increased, I concluded to extend its limit so as to include all the stars of which Right Ascensions and Declinations had been published in our volumes; and this, with a few exceptions, has been done. The idea of forming a General Catalogue of our observations had occurred to Mr. Ferguson; and he, assisted by Professors Hall and Eastman, collected 011 sheets the observations made from 184 5 to 18 50, inclusive; and the observations of 184 5 having been reduced by Professor Hall to 1 8 50, the collection was transferred to me for further reduction. The stars transferred to me were those of all the instruments, and the places of the-stars were united into one for each co-ordinate.
