The erector spina3 is immensely hypertrophied, and can be felt as a thick, hard mass on each side of the spine. The spinous processes of the vertebrse lie in a groove between these masses of muscle. In the space between the crest of the ilium and the last rib the thick hard edge of the erector spinse can be felt distinctly. The belly is big, but the muscles forming its wall do not <appear to be either wasted or hypertrophied. The cremasters act readily. The chest is broad and deep, and the costal angle exceed- ingly obtuse; its conical shape can be very distinctly seen, owing to the wasting of the pectorals. The serratus magnus is large, and its serrations can be seen with great clearness through the skin; it is not hard, like the erector spinaB, but appears to act naturally.
