Abstract
1. A description is given of the hot springs of Hammam Meskoutine, Algeria, and the principal animals and plants found living in them above a temperature of 38°C. 2. Life was found up to the following maximum temperatures: plants (blue-green algae), 58° C.; animals (Cypris balnearia), 51.5° C. 3. A comparison between the death-points of the principal animals and the temperatures at which they were living shows: (a) That some animals (Cypris balnearia and Bidessus signatellus) are confined to thermal waters. (b) That some animals can exist, for short periods, at temperatures above their eventual thermal death-points (Cypris balnearia and Rana ridibunda). (c) That some animals have death-points which vary with the temperatures at which they live (Barbus callensis and Potamon edulis).Keywords
