To the Editor:—  I should like to make a correction in the article on "Dinitrophenol Poisoning" reported by Drs. Jackson and Duvall in The Journal, June 2.Under the chemical analyses Dr. Jackson reported an icterus index of 20 on first examination. At the time the examination was made it was brought to Dr. Jackson's attention that the color obtained at that reading was almost entirely dissipated by the addition of 5 per cent hydrochloric acid. This is according to recommendation made by Dr. Tainter and his co-workers in The Journal of Nov. 4, 1933. A second determination could not be made at this time because of lack of serum. The second report of 5.3 was obtained on later serum (also dark in color), which was decolorized with 5 per cent hydrochloric acid.I make this correction in order that the report may not be accepted by some as conclusive
