In this astronomical chart (front and back) Gibbes provides a diagram of the phases of the eclipse and the circle of the Earth's shadow when the moon enters the shadow, eclipse begins, middle of eclipse, end of eclipse and the moon leaving the shadow. On the back of the page Gibbes provides the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter. Gibbes also provides the time of the aforementioned phases.
In this astronomical chart (front and back) on the front of the page Gibbes provides a diagram and the elements for constructing the diagram. Also included are his calculations of the partial lunar eclipse including the hourly motion, declination, hourly motion in declination, horizontal parallax, and semidiameter. Gibbes also provides the results of the eclipse (phases of the eclipse: beginning, middle, end and duration). On the back of the page Gibbes provides the calculations from the quantities given on the front page to calculate logarithms, the auxiliary quantities, and relative orbit described by the moon in one hour of time.
In this astronomical chart (front and back) Lewis R. Gibbes provides the mathematical calculations and diagram for a total eclipse of the sun in relation to time; the parallel of declination and Charleston, S.C.; the Equator; Earth's moon and the North Pole. Gibbes' calculations continue onto the back of the chart.
In this astronomical chart (front and back) Gibbes provides on the front page a diagram and the elements for constructing the diagram. Those elements are hourly motion, declination, hourly motion in declination, horizontal parallax and semidiameter. Gibbes also provides the result times of the eclipse including the beginning, total, opposition, middle, end of total, general and duration of eclipse. On the back of the page Gibbes provides his calculations for the result times.

In this astronomical chart Gibbes provides a diagram, its calculations and results (phases of the eclipse: beginning, middle end and duration), and the mathematical calculations for a total eclipse in relation to the elements of the eclipse. Those elements are time (Greenwich Mean Time), hourly motion, hourly motion in declination, relative motion, declination, semidiameter and horizontal parallex.
Frank R. Fisher's notes contain observations, drawings, and photographs relating to scientific studies, particularly astronomical observations made while Fisher was a resident in Charleston, S.C., during the 1880s. Fisher, a cashier at the South Carolina Railroad Company in Charleston, was an amateur scientist and inventor who occasionally worked in consultation with longtime College of Charleston professor Lewis R. Gibbes. Fisher's astronomical observations begin in Charleston in 1882 with the sighting of a comet. He also records his observations of the transit of Venus (1883), an aurora and sun spots (1892), and discusses new theories concerning Jupiter (1894) and the nature of the sun's corona (1892). He includes charts, drawings, and diagrams. Of particular interest are observations made during the Charleston earthquake in Aug. 1886 (pages 41-73). Other notes include inscriptions from buildings in Nineveh, Hebrew alphabets, the "hieroglyphic alphabet" and discussions on the Rosetta Stone and the statue of Memnon at Thebes. 123p. Full text.

In this astronomical chart Gibbes provides a diagram, its calculations and results (phases of the eclipse: beginning, middle, end and duration), and the mathematical calculations for an annular partial eclipse of the sun in relation to the elements of the eclipse. Those elements are time, hourly motion, declination, hourly motion in declination and horizontal parallax.
