as well as the stratigraphical horizon, of all his specimens. Bairstow 

 did this by drawing 1 7 datum lines on his copies of the maps (ie. they 

 are not on the originals in King's College, Cambridge). Each was a 

 straight line crossing the foreshore from the base of the cliff to the 

 seaward edge of the scar; most cross the foreshore approximately at 



right angles to the cliff, but a few cross at an oblique angle. Originally 

 he chiselled marks on the outcrops to record the exact position of 

 each datum line, but all such marks have long since disappeared. 

 Each ammonite he collected was related to the nearest point on a 

 datum line by pacing yards (0.9 m) from the intersection of the line
