  <dc:title>Plate, three nebulae observed in April 1852 and April 1855 by [William Parsons]</dc:title>
  <dc:description>Four figures showing nebulae observed by Parsons. The first two figures are two possible forms of a spiral nebula, either S-shaped or a standard spiral, observed on 13 April 1852. The second two figures are two nebulae, one with a wedge-shaped division and the other a brighter S-shaped spiral nebula, observed together in April 1855. The nebulae are drawn in graphite. The nebulae correspond to numbers 1085 and 1092 in William Herschel's catalogue of nebulae.
