Mr. Fisher on the errors in longitude , &c.. 
As an Appendix to these observations, I beg leave to add 
the following Table of Kates, furnished by Mr. Coleman, 
to which I have prefixed his letter as an introduction. 
157, Lcadcnhall-Strect , 
5th June, 1820. 
Sir, 
I n compliance with the wish of our common friend Lieutenant 
Everard Home, I have much pleasure in sending you a table 
of rates of chronometers. My profession as Teacher of 
Navigation, conjointly with Mr. Norie, which connects me 
so intimately with the Officers of the Honourable East India 
Company, employed on board the ships trading to India, 
has enabled me to present you with this table upon an en- 
larged scale. While engaged in the same service eighteen 
years, this subject occupied my attention, and it affords me 
much satisfaction that you are bringing the subject before 
the Royal Society. My remarks correspond very much with 
those, I understand, you are now bringing forward. 
I am, Sir, 
Your obedient servant, 
George Coleman.
