By re-computing thefe obfervations, I find, that 
the external contad of Venus happened at b** 5 ^ 
the internal contad at y*' 8 ' 21'', the beginning of 
theeclipfe of the Sun at 18^ 8' o", and the end at 
19^20' 33", all apparent time j and that the lati- 
tude of the place, by the mean of the 4 altitudes of 
Cor Scorpii, is 36° 4' 44 N. The dip of the ho- 
rizon of the fea, for an elevation of i6o feet, may be 
reckoned i 2' 5".
