X y°u my refpeCts, on occaflon of 
the paflage of Venus over the fun’s difk, on the 6th

Mellieurs Maraldi, De la Lande, and De Lifle,

flans, St. Hubert, and to the Chateau de la Muette, 
where the King s philofophical and optical chamber is.

time to the weft of the Royal Obfervatory, that I 
made my obfervations, in company with Monf. De 
Fouchy.

limbs of the fun, for want of a good micrometer, I 
made ufe of a quadrant of 24 feet, made by Lan- 
glois * and for obferving the egrefs, 1 had a good re-
