To quickly assess the difficulty of the text, read a short excerpt:
But such a parallel is not admissible from a closer and more e.x.act point of vioAv. E-^ery fall of temperature below SUMMER SLEEP, 121 the optimum diminishes the vital energy of the creature more and more, till at last, at the minimum, life becomes latent ; in this condition the animal can liv^e for a long time without danger, since the consumption of organic nutritious matter is at its minimum, or, as it ■would seem in eggs which survive the winter, almost entirely suspended during long perio...ds. If, on the other hand, the temperature rises above the optimum, the vital energies are more and more increased, often accompanied, no doubt, by phenomena which seem to indicate a certain deterioration in them ; but a condition of latent vitality never supervenes ; on the contrary, death always follows as the result of a too rapid consumption of the organic matter of the body. Thus the power possessed by many animals, both warm- and cold-blooded, of enduring without injury a higher temperatui'e than tha.t which kills protoplasm, remains as yet unexplained even by the parallel above suggested, and the solution of the problem would undoubtedly be of the highest interest.
