PlateXXIX. Upper or dorsal surface of the lungs of the ox, reduced to one-twelfth of the natural size:a,a', the right and left principal lobes. These are the largest and are situated posteriorly, resting upon the diaphragm;b,b', the ventral lobes, situated between the principal lobes; andc,c',c''the most anterior, or cephalic, lobes.
