I been in possession of
instruments, but was obliged to content myself with some of the elements
of that art, learned from books, and a few rude observations made with a
telescope, sufficient only to give me a general idea of the situation of
the heavenly bodies; for my short sight is insufficient to distinguish
the stars without the help of a glass.

I recollect an adventure on this subject, the remembrance of which has
often diverted me. I had bought a celestial planisphere to study the
constellations by, and, having fixed it on a frame, when the nights were
fine and the sky clear, I went into the garden; and fixing the frame on
four sticks, something higher than myself, which I drove into the ground,
turned the planisphere downwards, and contrived to light it by means of a
candle (which I put in a pail to prevent the wind from blowing it out)
and then placed in the centre of the above--mentioned four supporters;
this done, I examined the stars with my glass, and from time to time
referring to my planisphere, endeavored to distinguish the various
constellations. I think I have before observed that our garden was on a
terrace, and lay open to the road. One night, some country people
passing very late, saw me in a most grotesque habit, busily employed in
these observations: the light, which struck directly on the planisphere,
proceeding from a cause they could not divine (the candle being concealed
by the sides of the pail), the four stakes supporting a large paper,
marked over with various uncouth figures, with the motion of the
telescope, which they saw turning backwards and forwards, gave the whole
an air of conjuration that struck them with horror and amazement. My
figure was by no means calculated to dispel their fears; a flapped hat
put on over my nightcap, and a short cloak about my shoulder (which Madam
de Warrens had obliged me to put on) presented in their idea the image of
a real sorcerer. Being near midnight, they made no doubt but this was
the beginning of some diabolical assembly, and having no curiosity to pry
further into these mysteries, they fled with all possible speed, awakened
their neighbors, and described this most dreadful vision. The story
spread so fast that the next day the whole neighborhood was informed that
a nocturnal assembly of witches was held in the garden that belonged to
Monsieur Noiret, and I am ignorant what might have been the consequence
of this rumor if one of the countryme
