These, in the Horse,are smaller and more spherical at the periphery, larger and moreoval toward the centre, of the cortical substance, there offeringthe linear arrangement. Gland-vesicles also occur in the medul-lary substance of the Horses adrenals. In the Ox the trabeculartissue of the cortical substance defining the lobules is firm andwell-marked: the fatty globules are fewer than in Man. Thegland-vesicles are distinct in the adrenals of the Hedgehog. In.

Theirlength was one inch: their situation mesiad of the upper extremityof each kidney. They have a similar cylindrical figure, and largerelative size in the Porcupine and many other Rodents: they areshorter in the Muridce ; are roundish and somewhat flattened inLeporidcB. In a young Sloth I found the adrenal surpassing thekidney in size, and showing distinctly the cortical and medullarysubstances. In the Cetacea there is an interesting analogy betweenthe adrenal, in regard to its lobulated exterior, and the multi-lobate kidney. In the Elephant the adrenal is a depressed cone,with the base bilobed. In the Rhinoceros the adrenal bo
