Abstract
II. IN considering the effect of depth on the gaseous contents of sea water, Dr. Tornoe arranges his results in groups, giving the mean percentage of oxygen in different intervals of depth. From the consideration of this table he concludes that “the proportion of oxygen, which at the surface is 35.3 per cent, begins at once and continues to diminish, at first rapidly and afterwards at a slower rate, till it has reached 32.5 per cent. at the depth of 300 fathoms, from whence it keeps almost constant. I will not omit, however, to observe that of the samples of water examined, forty had been drawn from the bottom; it was, however, impossible to detect any difference in composition between these and the samples obtained from equal intermediate depths.”
