Sir — I am grateful for the opportunity to reply to the criticisms raised by Mr VincentCitation (5) . It seems to me that the bulk of his argument is concerned with the statistical treatment of the data that I presentedCitation (3) . However, he has apparently misunderstood the purpose of statistical analysis of results, and also seems to have missed the point of my paper. For example, he states that my results “are contradictory to all previous trials (sic) results”. My interpretation. arising from the method of analysis chosen, is that under the conditions of my trials, any apparent effect of fenbendazole could be due to chance.
