now went fo irregularly, that we made no farther ufe of it. 
The poor fellow was not lefs chagrined than we were, at 
our bad fuccefs; which, however, I am convinced was more 
owing to the miferable tools he was obliged to work with, 
and the ftiffnefs his hands had contracted from his ordinary 
occupation, than to his want of fkill. 
For the fatisfaCtion of thofe who may with to have a 
general view of its rate of going, I have added the follow¬ 
ing table. 
The firft and fecond columns contain the dates when, 
and the names of the places where, its rate was obferved. 
The third column contains the daily error of its rate, fo 
found from mean time. The fourth column has the lon¬ 
gitude of each place, according to the Greenwich rate; that 
is, calculated on a fuppolition that the time-keeper had not 
varied its rate from the time it left Greenwich. But as we 
had frequent opportunities of afcertaining the variation of 
its daily error, or finding its new rate, the fifth column 
has the longitude according to its laft rate, calculated from 
the true longitude of the place laft departed from. The 
fixth is the true longitude of the place deduced from aftro- 
nomical obfervations made by ourlelves, and compared 
with thofe made by others, whenever fuch could be ob¬ 
tained. The feventh column fhews the difference between 
the fourth column and the fixth in fpace; and the eighth 
the fame difference in time. The ninth fhews the number 
of months and days in which the error, thus determined, 
had been accumulating. The difference between the fifth 
and fixth columns is found in the tenth, and fhews the er¬ 
ror of the time-keeper, according to its rate laft found, in 
fpace; and the eleventh, the fame error in time. The 
twelfth contains the time elapfed in failing from the place
