  <dc:title>Letter, from Thomas Maclear to Sir John Herschel</dc:title>
  <dc:description>Autograph letter signed by sender. Polar region was thick this evening so that very minute stars were invisible. Set C. P. Smyth to the transit and himself at the circle to observe John Frederick William Herschel's list of stars. Received the spherometer safely. Intends to stake out the base line again on Tuesday. [Andrew?] Sm[y]th's expedition will be a serious undertaking in the Eastern direction.</dc:description>
