Synopsis

MARS AS THE ABODE OF LIFE FOREWORD UP to the middle of the nineteenth century, astronomy was busied with motions. The wanderings of the planets in their courses attracted attention, and held thought to the practical exclusion of all else concerning them. It was to problems of this character that the great names of the past - Newton, Huygens, Laplace - were linked. But when the century that has gone was halfway through its course, a change came over the spirit of the investigation; with the advance in physics celestial searchers began to concern themselves with matter, too. Gravitational astronomy had regarded the planets from the point of view of how they act; physical astronomy is intent upon what they are. One outcome of this more intimate acquaintance is the new study with which the present papers deal: the evolution of the planets regarded as worlds. Such research has to do not merely with the aggregation of material, but with its subsequent metamorphoses
