An aerial view of a German Benedictine Monastery compound. A small town is nestled at the foot of a hill in the background. The monastery includes a ditch surrounding the outer wall, stables, gardens, graveyard, workshops, church, cloister, living quarters, and various other buildings. It is pictured as it would have looked at the end of the Middle Ages.

"The compound ascidians, or <em>Botryllidae</em>, are united togetyher by the coalescence of of their mantles, so as to form a leathery or gelatinous mass, ususally attached to stones or sea-weed; in this the seperate animals are imbedded round a common canal, many of them being adorned with beautiful colors, and these masses are of an almost infinte variety of forms." &mdash; Goodrich, 1859

"The eyes, which are among the most wonderful objects in nature, are almost always of the kind called <em>compound</em>, that is to say, they consist of a multitude of little hexagonal facets, brought close together on each side of the head, each furnished with a cornea, a lens, a coating of pigment, and a nervous filament, and being in fact a true eye." &mdash; Goodrich, 1859

"Find the center of gravity of two of the bodies, as W1, and W4, in fig 4. Assume that the weight of both bodies is concentrated at C1, and find the center of gravity of this combined weight at C1, and the weight of W2; let it be at C2; then find the center of gravity of the combined weights of W1, W4, W2 (concentrated at C2), and W2; let it be at C; then C will be the center of gravity of the four bodies." &mdash;Hallock 1905
