    retaining their normal structure, were considerably hypertrophied. They were twice or three times the size of normal fibers from corresponding muscle utilized as control preparations. Muscle fibers vary considerably in size even under normal conditions. Ini Fig. 4—Muscle showing transverse striations. Paramyoclonus multi- plex. general, the larger the muscle the larger is the muscle fiber. In man the minimum diameter is given as io micromillimeters; the maximum as ioo micromillimeters. In the case under considera- tion, the larger proportion of the muscle fibers on transverse sec- tion averaged a diameter of 150 micromillimeters, many measur- ing 175 micromillimeters. This increase in size of the fibers not universally distributed over the microscopic field. In round numbers, two thirds may be said to have presented this change.
