The clock taken down, and the pendulum fecured, as at the 
cape of Good Hope, after the direction given per Mr. Ellicott 
the maker. 
From the mean of a great num- 
ber of obfervations, taken at I ( November 68.7 'j from 1 2th 
different times of the day and >in< December 70.3 > to 
night, Farenheit’s thermo- l January 72.3 J the 1 8th. 
meter ftood at - - - - J 
The thermometer was hung by the fide of the clock, and I never 
faw it higher (from 12th of November 1761 to January 18th, 
1762) than 74* , or lower than 67. 
Thofe obfervations marked : are a little dubious.
