Total of all tunnels: ?? epidid large 32 medium 3 small 8 43 ?? nipple large or medium 25 small 12 tiny 19 56 Weights of [illegible] specimens ?? epidid large 8.1, 7.7, 8.4, 7.4, epidid small 9.5, 10.0, 10.2, 8.8 ?? nipple small-med. 10.0, 9.3 The leaniness of young males seemed due to more fat than an old male.
