Total eclipse of the Sun, May 28, 1900.—Account of the observations made by the Solar Physics Observatory Eclipse expedition and the officers and men of H. M. S. 'Theseus' at Santa Pola, Spain

The Report gives details as to the erection of coronagraphs, prismatic cameras, and other instruments, and of the results obtained by their use during the eclipse, which was observed under very favourable circumstances. Some of the more obvious results have already been stated in a Preliminary Report, and the following remarks may now be added. A comparison of the photographs taken with the coronagraph of 16 feet focus with those taken about two hours earlier in America indicates that while some of the prominences changed greatly in appearance in the interval, no changes were detected in the details of the corona.
