118 The Rev. Dr. Robinson on the Longitude of the Armagh Observatory/ . 



Konlgsberg, 8 of first L. 

 „ 4 of second L, 



38.17 

 26.69 



26.37.24 



The differences are considerable, but I think the mean 



26.35.64 

 must be very near the truth. 



I have had few chronometric results previous to Mr. Dent's visit, and those 

 obtained with my pocket-watch. Sharp, 1760, during my visits to London, &c. 

 under unfayourable circumstances. They are : 



Greenwich, 2 pair 

 Kensington, 3 do. 

 Edinburgh, 1 do. 



26.35.44 

 34.54 

 36.04 



26.35.09 



But the weights of these being much less than those of the results obtained 

 with Mr. Dent's watches, can only be considered as depressing a little the mean 

 of them. 



On the whole, therefore, I am not inclined to change the quantity which 

 some years since I gave to Mr. Stratford for insertion in the Nautical Almanac, 



+ 26.35.50.
