Two pages, 12mo, fold marks, one edge stained and roughened (perhaps blank second leaf of bifolium removed, and item tipped into album), text clear as follows: "The points which are partally fixed in Ireland extend to the southward as far as Bray Head on the East Coast. And they can be given to the Admiralty Surveyor if required in the course the present year. The North East Coast is already surveyed, and may be copied by the Admiralty surveyors at any time. But though the Survey is proceeding rapidly to the southward I should not like to hazard a guess as to the time when Dublin Bay would be surveyed." See Wikipedia biography for some detail concerning the Irish survey and Colby's personal life in 1828 (marriage).
