Abstract
IT will be a source of satisfaction to all astronomers that this bouquet of writings gathered in homage to Seeliger was published before his lamented death in December last. The volume consists of thirty-six papers, embracing subjects from abstract dynamics on one hand to the latest astrophysical problems, both experimental and theoretical, on the other. The value of the contributions is sufficiently guaranteed by the list of authors, and though selection is invidious, the names of Jeans, Eddington, Schwarzschild (pre sumably a hitherto unpublished fragment), von Zeipel, Eberhard, Kohlschiitter, Plaskett, Emden, Bergstrand, Schlesinger and Shapley will give an indication of the standard maintained. Some of the articles consist entirely of original research. Others give a general summary of recent work in some particular branch-summaries not easily found elsewhere. As particularly valuable ones may be mentioned Ludendorff's “On the relations between the different classes of variable stars,” and Guthnick's “Twelve years of photoelectric photometry at the Berlin Observatory”; also Stromgren's (of which the title had better be left untranslated) “ZuDurchmusterung des Probleme restreint.” A paper by van Rhijn contains evidence throwing doubt upon the supposed non-existence of M-stars intermediate between giants and dwarfs. Many of the papers are such as can be read with ease by those not specialists in the particular subjects concerned.
