The authors of the paper on The Insensible Loss of Water, p. 1, volume 22, no. 1 (January 1942) desire to record the following corrections: p. 6: The column at the right of figure 1, designated “grams,” should start at 517 and increase by 345 for each interval. In the legend of this figure the phrase “or grams of water vapor per 24 hours” should be transferred to the end of the last sentence. p. 14: Reference (67) following “Rubner” should become (65). p. 16: Reference (68) should be deleted.
