^4 inches. I am the rather induced at prefent to 
mention this, as the latitude of Oxford, given by 
Mr. De la Lande in the ConnoiJJance des TempSy 
and attributed to me, was determined by the late 
ProfelTor Blifs, from obfervations made with a fmaller 
and lefs perfect inftrument. The longitude of Ox- 
ford is 5' 3'' or 5' 4'' to the well; of Greenwich, 
the former quantity being deduced frow a compa- 
rifon of the Sun’s ecliple, obferved by myfelf, with 
Mr. Short’s’ obfervation, an allowance being made in 
the computation for the figure of the earth, in the 
effect of the Moon’s parallax.
