Not illustrated. 1877 Excerpt: ... are observed on week-days in the first half of each lunation (the other half being effectually secured under the administration of M. Le Verrier). The moon is observed when visible at meridian passage on every day, without any exception. The Astronomer-Royal says, " The number of small planets has now become so great, and the interest of establishing the elements of all their orbits so small, --while at the same time the light of all those lately discovered is very faint, and the difficulty and doubt of observation greatly increased, --that I have begun to think seriously of limiting future observations to a small number of these objects. A German society proposes to observe in the next year, among the planets whose elements are known most accurately, a fist of seventeen planets, including all which are sufficiently bright to be observed with few chances of mistake, and a sufficient number possessing the various characteristics of small and large inclinations and excentricities, and proximity to Mars and to Jupiter. This proposal appears to me to be probably worthy of attention at Greenwich." With the altazimuth, the moon and corresponding stars have been observed without intentional loss of a day on which she was visible. Amongst the observations made with the transit-circle, are 3485 transits, the separate limbs being counted as separate observations; 3374 circle-observations, each requiring a separate reading of the six, four, or ten microscopemicrometers. With the reflex-zenith-tube 39 pairs of observations of y Draconis were made, the instrument being reversed between the observations, and 5 single observations. With the altazimuth, amongst other observations, 791 azimuths of the moon and stars, and 367 zenithdistances of the moon were taken. ...
