...This will be evident, on consideration. I am therefore disposed to believe that the plumb-line was drawn towards the south, from the action of matter,...producing that deflection extends in a southern direction beyond Arbury Hill. If the error, though not probable, as above observed, be supposed to exist at Dunnose,... | |

...if taken at 52° 50' 23",38, by about 8", nearly answering to 2" on each degree. A deviation of 8" J from the true vertical is a large quantity, nor can the cause of it be assigned, unless it be supposed that the matter producing such deflection extends in a .southern direction beyond Arbury Hill."... | |
