OP THE SOLID CEUST OF THE EAETLI.

Minicoy Island is about 250 miles west of Punnae. Its average radius is about 2'5 
miles; and three miles from the shore the sea is about 300 fathoms, or about one-third 
of a mile. If, then, to make our cylinder accord with this case, right angles being cut 
down, we make a= 5 and 7i=l, we have 
m— 50. 
Til — 100.

Under the heading “ Correction for Local Attraction” Dr. Young's is found by taking 
one third for the “Reduction for Height” in Table III. The three columns for Plains, 
Himalayas, and Sea are taken from paragraphs 15, 19, 21, 22. These three columns, in 
each case of to, are added together, and after the values for Punnae are subtracted the 
results are recorded in columns B and C. 
In order the better to compare these results with the quantities which are to be ac- 
counted for, I compile the following Table from the columns A, B, C of Table VII. 
The sign + indicates a force acting downwards. In all the columns the numbers are 
the last figures of seven places of decimals in the ratio to gravity, the decimal point and 
ciphers being omitted for convenience.
