Erratum

In the article by Takashi Taniguchi, Motohatsu Fujiwara and Kiyoshi Ohsumi, Vol. 201, No. 3, June 1977, the following correction should be noted. On page 681, the figure legend should read:

FIG. 1. Histofluorescence of rabbit heart. Endocardial surface is on upper side. A. The walls of right atrium. The fluorescent material is localized to varicose fibers. The density of the fibers is lower than in the S-A node. B. The area I of the S-A node in figure 2. The fluorescent nerve fibers surround the muscle fibers of the specialized tissues. The area is occupied by a large number of connective tissues. C. The area II of the S-A node in figure 2. The fluorescent nerve fibers are distributed densely and surround the muscle fibers of the specialized tissues. Connective tissues are less developed. (x120.)
