On my visit to the Observatory, however, I had not leisure to examine minutely the means by which the images of stars and planets were produced.

I reserved this examination for a second opportunity, which, as it happened, never occurred.
On this occasion Eveena and Eunane were with me, and the astronomic pictures which were to be presented to us, and which they could enjoy and understand almost as fully as myself, sufficiently occupied our time.

Warned to stand at such a distance from the central machinery that in a whole revolution no part of it could by any possibility touch us, we were placed near an opening looking into a dark chamber, with our backs to the objects of observation.

In this chamber, not upon a screen but suspended in the air, presently appeared an image several thousand times larger than that of the crescent Moon as seen through a tube small enough to correct the exaggeration of visual instinct.

It appeared, however, not flat, as does the Moon to the naked eye, but evidently as part of a sphere.
