DR. BARTLETT.

The further any thing is from us, the smaller it appears; as that kite for instance, it will appear much less in the air, than it does on the ground.

CHARLES.

Certainly; and this is also a proof, that the sun must be amazingly great, because that it is at such an immense distance from us. The moon, by the same rule, must be very large.

DR. BARTLETT.

The moon is large; but much less than the earth. There are stars which are of a much superior magnitude.

WILLIAM.

We should not think so.

DR. BARTLETT.

That arises from the stars being still further from us than the moon.
