ihe iecond column of the fecond Tabic contains 
the obierved duration, or interval of time, between 
the two internal contaas ; the third contains the dif- 
ference of each duration, deduced by computation 
upon afupporuion that the Siin’s parallax wasr^8", 
on the day of the tranfit; the fourth, the differenc 
ot that duration, as determined by adual obferva- 
tion : In the laft column is given the horizontal par-^ 
Silax on the day of ihe tranfit, refulting from a 
companfon of the third and fourth column^ 
Iri the above comparifon, I have, u fed Captain 
Cook s o^ervation at the ingrefs, and a mean of his 
and Mr. Green’s obfervations at the egrefs ; becaufe 
. upon a comparifon of the oblerved times at the in- 
grds and egrefs, made at the feveral places, when 
reduced to the center of the Earth, upon a fuppo- 
htion that the Sun’s parallax on the day of the tranfit 
was 8 ,65, the difference of meridians, as deduced 
trorn Captain Cook’s obfervation at the ingrefs, a<^rees 
much better with the fame differences deduced from 
a mean of tne two obfervations at the egrefs, than 
diofe denved either from the obfervation of Mr. 
Oreen, Dr. Solander, or even from a mean of all 
the three obfervations, as appears from the following
