There are two large lymph glands antl a inmihcr of Inemolymph glands above the phar\ni.\. The CESophagus has a lumen of about an inch (ca. cm.) when moderately distended; otherwise it resembles that of the ox. The stomach is like that of the ox in its general arrangement. Its average capacity is about four gallons (ca. 15 liters). The cardia is opposite the eighth intercostal space; it is just to the left of the median plane, and about two inches Dorsal curviitiirc <if rumc. fcl'"" ' lja<^ r Posterior groori- of ninuii I photograph of specimen hardened in silu. The reticulu (ca. 5 cm.) l)elow the vertebral cohnnn. The dorsal sac of the rumen is a little longer than the ventral sac and extends considerably (ca. cm.) further forward than the latter. The ventral sac is relatively larger and extends further to the right of the median plane than in the ox; its posterior blind sac extends further (ca. 6-8 cm.) back than that of the dorsal sac. The parietal attachment of the dorsal sac extends back to the second lumbar vertebra. The left longitudinal groove ex- tends upward and backward for a short distance only, and therefore does not connect with the posterior groove. There are two longitudinal grooves on the right side which join at each end, thus enclosing a long, narrow prominent area; the dorsal one contains the right ruminal artery, and the ventral one corresponds to.
