Sir.—In a recent reply letter in the May 1988 issue of AJDC, Drs Specker and Tsang1 claimed that Dr Chesney and I provided spurious data regarding the radial bone mineral content of children at age 6 years.2 In fact, the values we provided were correct in grams per centimeter as opposed to the values in grams reported by Drs Specker and Tsang in their reply letter. By way of clarification, the values reported by Mazess and Cameron2 were 0.486 g/cm and 0.475 g/cm for male and female children, respectively, whereas the value at age 6 years as reported by Specker et al3 in their original report was 0.356 g/cm. These are the values reported in our previous letter. It is unfortunate that Drs Specker and Tsang misread the table provided in the Mazess and Cameron article.
