As { am anxious to determine the error of the Astronomical 
Tables by means of the observations made on the late solar 
eclipse, I should be much obliged to you, or Dr. Burney, to com- 
municate, through your Magazine, the latitude and longitude of 
Dr. Burney’s Observatory at Gosport. 
I am, dear sir, yours respectfully, 
To Dr. Tilloch. Gro. INNEs. 
VII. Remarks on Mr. Rippxe’s Claim to the Invention of a new 
Method of determining the Latitude. 
Edinburgh, June 8, 1821. 
Sir, — As an article by Mr. Edward Riddle has been inserted 
in the Philosophical Magazine for May 1821, which appears to 
me to contain insinuations totally unfounded, I beg leave to ar 
a few words in reply. 
General Brisbane having been abroad for some tine expresses 
himself as follows, in his Memoir on the Repeating Circle, Edin- 
burgh Philosophical Transactions, vol. ix. Part I, page 97, &e. 
and read in February 1819.
