Erratum.
Figure 1 in the report "Ice nucleation by, alcohols arranged in monolayers at the surface of water drops" by M. Gavish et al. (16 Nov., p. 973) should have been credited to B. Kamb [in Structural Chemistry and Molecular Biology, A. Rich, Ed. (Freeman, New York, 1968), pp. 507-542, figure 3a].
