Eight months later the museum officially opened to the public. "It contained 80,000 square feet of exhibit space with specially designed mahogany exhibit cases. The exhibit halls contained exhibits on geology, metallurgy, zoology, medicine, anthropology, art, history and technologies such as ceramics, printing, transportation, textiles, fisheries, and agriculture." Under the guidance of George Brown Goode, a historian and ichythyologist, a Division of Arts and Industries and Materia Medica was established that same year and materials from the museum were sent to many late nineteenth century expositions to teach people about the country's political and natural history.
