A few alterations have been found necessary in gathering them into a consecutive whole, and each chapter has been carefully revised. With respect to the illustrat. ions, several of which did not accompany the papers in their original form, I am indebted to the kindness of Mr. A. Cowper Ranyard, the editor of Knowledge, for permission to reproduce the photograph of the Moon, taken with the Great Refractor of the Lick Observatory Frontispiece, Mr. Lassells picture of the Great Nebula in Orion, and drawings of the Rev. F. Howletts photographs of sun-spots of 1882-3. To the Council of the Royal Society I owe thanks for a similar favour in regard to the Krakatoa diagrams. The object of the book is to give the general reader some sketches of specially interesting matters relating to the different heavenly bodies.

Steele, for their aid in revising the work. ROBERT S. BALL. OBSERVATORY C , O . DUBLIN. Apd, 1894. - CONTENTS - CBAPTPR A61 I . E HEAT OF THE SUN.
