One part of the remaining copies may be offered for sale, and the other carefully preserved, to form complete sets of the work, to supply the demand from new institutions.
Página 10 - The following are some of the subjects which may be embraced in the reports:* I. PHYSICAL CLASS. 1. Physics, including astronomy, natural philosophy, chemistry, and meteorology. 2. Natural history, including botany, zoology, geology, &c. 3. Agriculture. 4. Application of science to arts. II. MORAL AND POLITICAL CLASS. 5. Ethnology, including particular history, comparative philology, antiquities, &c.
