 * Section 1: remeasure Hounslow base with new chains. Result 27404.315. Correct Roy value 27404.084. Mean 27404.2 ft. SECT2(441/29): Triangles south to IOW Dunnose. Then link to Rot grid and test accuracy. Early possibility of a meridian arc. 2 Improvements to theodolite. 3 White lights. 4 Angles. 6 Dunnose latitude 9 stations (15 in number) (many later rejected) SECT3(474/60) 1 Salisbury base 36574.4 SECT4(488/75) Sides 2Spherical excess then correct angles  4 Calculate salisbury from hounslow 36574.7 (one route) Find other routes. SECT5(517/105) Meridian at Dunnose and azimuths SECT6(530) distances from meridian. lat/lon coords 7ellipse datum SECT7(539/126) secondary triangles (160 in number) have only two angles measured (unlike three angles for the main survey) SECT8(567/155) bearings and distances and lat lon of secondary objects. SECT9 (579) heights start from dunnose by levelling. other heights by reciprocal elevations CONCLUSION(589/176)  small instrument FIGURES/maps (592/179)

Clarke Ordnance Survey publications
The following list contains the major reports prepared by Clarke, as well as his text book. The title pages of many of the reports mention only Colonel Henry James, Superintendent of the Ordnance Survey, but in every case it is made clear that Clarke was de facto author.
