ANNUAL MEETING, JANUARY 5TH, 1863. President in the Chair. Twelve members present. Ferdinand, Freiherr von Richthofen, was elected Corresponding Member. The committee on the meteoric iron, presented to the city by General Carleton, reported that permission had been obtained by Professor Whitney to saw a piece from it for analysis, and for distribution to some of the most important collections in this country and in Europe. A piece will be forwarded to Professor Brush, of Yale College, for analysis, and a description of the mass published in the Proceedings of the Academy, as soon as the returns of the analysis have been received. The Annual Reports of the officers of the Society for the past year (1862) were received, and the following is an abstract of their contents: The Report of the Treasurer was read, and referred to the Finance Committee. The Curator of Palæontology reported, that the number of specimens in the collection is 1,007, exclusive of numerous duplicates. They are principally from the cretaceous and tertiary formations of the Pacific coast. The collection has been rearranged in the course of the past year, and is now in as good condition as the accommodations of the Society will admit. The Curator of Botany reported, that 2,160 specimens were added to the collection during the year 1862, making a total of 6,160 specimens in the Academy’s herbarium. About twenty new specimens have been described in the Proceedings during the past year, and specimens and drawings of all of them have been placed in the collection. The herbarium is in good condition. The Curator of Entomology made a verbal report, to the effect that the collections in his department, although small, are in good order; but that few additions had been made during the year.
