HISTORY OF MAURITIUS. 
Observations on the Latitude. 
" As the Sun passed at noon too near the Zenith, I determined the latitude by 
the meridian altitude of six stars, three of which were on the north side, and three 
on the so utli.

“ It appears, therefore, that the real height of the Equator is 69° 8' 17", and con¬ 
sequently the elevation of the Pole 20° 51' 43". It is also evident that the quadrant 
made the altitudes appear too little by 26". 
“ The quarter of St. Denis being at the foot of Cape Bernard, which is the north¬ 
ernmost point of the Isle of Bourbon, the latitude of this Cape, which was due west 
of the place where I lived, at the distance of five or six hundred paces, may be de¬ 
termined to be 20° 51' 43". 
Observations on the Longitude. 
« February 9, 1754, at i2 h 34' 7 " true time, the first satellite of Jupiter appeared 
to me to come forth from the shadow: it seemed rather to adhere to the body of the 
planet, which was in opposition to the Sun on the 1st of this month.
