...shower, which numbered only about four hundred and fifty Leonids in all, the number of successful photographs was remarkably large. On each of two plates there were three trails and a single distinct trail was found on each of twelve others. It will now be possible to locate the radiant from which the Leonids proceed, by tracing back the trails photographed on the plates and determining the point at which they intersect...
...Observatory also succeeded in photographing the same Leonid with two cameras a mile apart. By the parallex method, using this mile as a base line, it will be possible to obtain the height of the radiant...
...about seven dozen photographs were made and although they have not as yet been carefully examined their development shows them to have been fairly successful. The Observatory succeeded in getting several photographs of the Leonids' trails and by the use of them will probably be able to locate the radiant. Two plates seem to show photographs of the spectra of the Leonids. This is an unusual success, as it is very difficult to photograph the spectrum of a falling body. It cannot be stated positively that photographs of spectra have been obtained until a more careful examination has been made...
...shower. Four cameras have been mounted on a platform moved by clockwork so that they will cover the same sixty degrees of the sky, throughout the entire shower. Six other instruments will be in use for determining the spectrum, magnitude and distance of the Leonids, and the radiant from which they come...
