APPENDIX. 
The following statement will shew the degree of correctness with which 
these four chronometers had maintained their respective rates, deduced 
from their going in the last three months at Winter Harbour; the same 
which are specified in Table V., under the title of “ Average daily 
rates.” 
The difference of each chronometer, on mean observatory time at Winter 
Harbour, is given in Table V. ; the observatory time was 5".3 slow of 
mean time at the Hecla’s winter station, as deduced from the bearing and 
measured distance ; the difference of the meridians of Greenwich and of 
the Hecla’s station, was 7 h . 23 m . 14 s . the longitude of the latter being- 
110 0 48' 30" west ; these data give the differences of the chronometers 
on Greenwich time on the 31st of July, as follows : —

By applying to each chronometer the allowance for its rate in 104 days, 
agreeably to the average daily rates in Table V., and adding ll m . 22.5 s . to 
No. 253, in compensation of an accidental stoppage to that amount on the 
3d of September*, the differences of the chronometers on Greenwich time 
on the 12th of November, conformably to the rates, are as follows: — 
h. m. s. 
228 slow

* Mr. Hooper and Captain Sabine having accompanied Captain Parry on shore on the west coast 
of Davis’ Strait, on this day, their return to the Hecla was delayed by unforeseen circumstances 
until between five and six hours beyond the usual time of winding the chronometers. Fortunately 
253 was the only one which had gone down ; being wound up and set in motion, it was com- 
pared with the other chronometers, and due allowance having been made for its rate since the 
comparison at noon of the preceding day, it was found to have been stopped for llm. 25.5s., 
which loss is accordingly brought into the account.
