In Reply.—I do not believe, as Dr Jorgenson and his colleagues suggest, that I have understated the case for considering dental anomalies to be a constant feature of the Morquio syndrome. The whole point of my article is summarized in the abstract, in which I wrote: "These defects [ie, of the enamel] are an apparently constant feature of the Morquio syndrome, and are therefore important aids in the differential diagnosis."
There is an unfortunate printer's error in the first sentence of the third column of page 1447. That sentence should read: "There is now [as opposed to "no"] sufficient evidence available to conclude that enamel defects are a constant feature of the Morquio syndrome." While this misprint may have contributed to any misunderstanding, it should have been readily apparent that it was an error in view of the rest of the article.
