Erratum
In the report "High-resolution chromosome sorting and DNA spot-blot analysis assign McArdle's syndrome to chromosome 11" by Roger V. Lebo et al. (6 July, p. 57), errors occurred in the legends for figures 1 and 2. In the next-to-last line of the legend for figure 1, "Lief bucket" should have been "Leif bucket." In the fifth line of the legend for figure 2, "
-globin" should have been "
-globin."
