"When the Moon falls into the shadow of the Earth, the rays of the Sun are intercepted, or hid from her, and she then becomes eclipsed. when the Earth's shadow covers a part of her face, as seen by us, she suffers only a partial eclipse, one part of her disc being obscured, while the other part reflects the Sun's light. But when her whole surface is obscured by the Earth's shadow, she then suffers a total eclipse, and of a duration proportionate to the distance she passes through the Earth's shadow." —Comstock, 1850

"When the moon psses between the Earth and Sun, there happens an eclipse of the Sun, because then the Moon's shadow falls upon the Earth. A total eclipse of the Sun happens often, but when it occurs, the total obscurity is confined to a small part of the Earth; since the dark portion of the Moon's shadow never exceeds 200 miles in diameter on the Earth. But the Moon's partial shadow, or penumbra, may cover a space on the Earth of more than 4,000 miles in diameter, within all which space the Sun will be more or less eclipsed. When the penumbra first touches the Earth, the eclipse begins at that place, and ends when the penumbra leaves it. But the eclipse will be total only where the dark shadow of the Moon touches the earth." —Comstock, 1850

"Umbra and Penumbra. A solar eclipse, with the penumbra, d, c, and the umbra or dark shadow is seen here. When the Moon is at its greatest distance from the Earth, its shadow m o, sometimes terminates, before it reaches the Earth, and then an observer standing directly under the point o, will see the outer edge of the Sun, forming a bright ring around the circumference of the Moon, thus forming an annular eclipse." —Comstock, 1850
