...circulars recently issued by the Observatory describe the work being done on the accumulated photographic plates which has been made possible by the grant lately made by the Carnegie Institution and by record observations made by Professor O. C. Wendell in regard to the transparency of comets to stellar bodies. The plates under study have been made both at the Cambridge station and at the Observatory in Peru. From the observations made by Professor Wendell he disproves the statement that comets are perfectly transparent. In addition to data on these two subjects observations are recorded on missing asteroids, whose disappearance...
...station in Peru, observations have been made along new and unique lines of work with the Henry Draper Memorial instruments. First, the spectra of large numbers of stars have been photographed simultaneously, with the result that large numbers of objects having peculiar spectra have been discovered. Secondly, stellar spectra, six inches long, and showing several hundred lines, have been obtained, demonstrating that large numbers of stars have identical spectra. Thirdly, photographs of the entire sky have been taken night after night, which, with the photographs taken in previous years, furninsh a complete history of the heavens since...
