From the Expanded Diary of Pedro Font:
"Friday, October 27.— I observed at this place of Tuquison, and found it to be without correction in latitude 32° 30', and with correction in 32° 22', and so I say: near the pueblo of Tuquison, outside of it a league to the north, on October 27, 1775, meridian altitude of the lower limb of the sun, 44° 26'."

Padre Font used a Mariner's Quadrant to determine latitudes along the route.
