According to Sir Robert Ball the whole difficulty of finding out the causes of the Glacial period vanishes when the solution of the problem is sought for in astronomy rather than in geography. Changes which seem to be so gigantic on the globe are, it is said, but daily wrought by cosmical forces with which we are familiar in astronomy, and one of the chief merits of Croll’s theory is supposed to consist in the fact that it satisfactorily accounts for a succession of Glacial and Inter-Glacial epochs during the Pleistocene period. Dr. Croll in his *Climate and Time* and *Climate and Cosmology* has tried to explain and establish his theory by elaborate calculations, showing that the changes in the values of the variable elements in the motion of the earth round the sun can adequately account for the climatic changes in the Pleistocene period. We shall first briefly state Dr. Croll’s theory, and then give the opinions of experts as regards its probability.
