' Life conquers the Land '

(From Edinburgh)
Contrast living conditions in water with those on land and you will note wetness,denseness, and dissolved air as against dryness and free air. Land plants and animals must depend upon their own structure to support their weight in such a light medium as air ; and must be able to breathe the dry oxygen of the air. All the evidence goes to prove that living things originated in water, and that in course of time some were able to forsake the water and gain a foot-hold on land. How this came to pass is Professor Peacock's subject today.
