An easy introduction to astronomy for young gentlemen and ladies : describing the figure motions, and dimensions of the earth : the different seasons : gravity and light : the solar system : the transit of Venus and its use in astronomy : the moon's motion and phases : the eclipses of the sun and moon : the cause of the ebbing and flowing of the sea, &c.
An introductory astronomy textbook by the Scottish instrument maker and lecturer James Ferguson, issued in 1812 by Johnson and Warner of Philadelphia for young readers. Copper-engraved fold-out plates combine bare geometric line work — ellipses, orbital paths, ray bundles keyed by letters — with shaded globes, moon phase sequences and a sun drawn as a saw-toothed disc, useful as diagrammatic line motifs.
