The rope used November 17 and 18 was measured, and its 36 feet mark was 

 found to be 30 feet 8 inches ; a proportionate reduction of the readings, as recorded, 

 is therefore to be made. 



A new rope was used between November 19 and December 10; the distances 

 from foot mark to foot mark, along its- range, are recorded as follows: —
