    exposed to it for a greater length of time, even at a tension far below the one which kills quickly. Bert observed that the development of eggs and the metamorphosis of insects were injured by a long stay in pure oxygen under ordinary pressure. When we inhale pure oxy- gen its consumption and the formation of carbonic acid become diminished. The delete- rious effects of excess of oxygen and overac- cumulation of carbonic acid when occurring together cause an animal to perish even when neither of the two gases by itself is present in a dangerous dose. Pflueger, in order to bring the remarkable effects of compressed oxygen nearer to our un- derstanding, has called attention to its analo- gous behavior toward phosphorus. In pure compressed oxygen phosphorus does not give light and does not absorb oxygen; as soon, however, as sufficient nitrogen is added, or the pressure is diminished, the production of light takes place and the oxygen becomes absorbed. Altho carbonic acid is a matter for excretion and life can be continued only when this gas is [14]
