To the Editor:—  It should have been as apparent to us as it was to several friendly critics that the evidence presented in our report (The Journal, Sept. 5, 1942, p. 25) did not warrant the statement in the summary that we were dealing with a case of chronic essential pentosuria. Using the same tests as were used at the time of the original study (as well as additional tests), seven collections of the same patient's urine at intervals between September 1942 and January 1943 were found to contain no pentose. This further evidence, in our opinion, makes it clear that the reported pentosuria was transitory, certainly not "chronic," and doubtfully worthy of the designation "essential."
