This notebook was kept by Amasa Holcomb (1787-1875), a self-educated surveyor and telescope maker. It contains notes of observations, records of telescopes made and sold, and some notes and formulas pertaining to the construction of instruments. Two descendants, Grace E. Holcomb Steere and Eva C. Holcombe Storey, gave it to the Smithsonian in 1933.
