Arkless and Graham (1967) , in reviewing a case which had been previously described as pseudo-pseudohypoparathyroidism by Miles and Elrick (1955) , discussed the roentgenographic relationships and semantic problems involving brachydactyly, cone epiphyses, peripheral dysostosis and pseudo-pseudohypoparathyroidism. The present study will present the results of a roentgenographic examination of the hands of a sample of normal school children and will discuss these results with respect to each of the four above-mentioned conditions.
