In this convolutional plan, as thefigures borrowed from Owens Anatomy of the Verte-brates show, the primary convolutions of the two halvesof the Cerebrum converge from behind forwards, as faras the anterior third of the Cerebral Hemispheres—andthence diverge in different directions.*. Fig. Q3.—Brain of the Rock Coney, side view. Fig. 94.—Brain of tlie Giraffe,side view. Starting from another small form, the Pigmy Chevrotain(Tragulus), we may find a similar convolutional develop-ment attaining to higher t3^es of the same general patternin the Stag (fig. 91), the Sheep, the Ox, the Giraffe(figs. 92, 94), the Camel, the Hippopotamus and theElephant (fig. 95). The greater convolutional complexityof the brain in these larger forms is represented in detail,as Owen has pointed out, by the fuller development of theprimary fissures, by their more sinuous course, and by * The letters and numerals in the several figures are always thesame for corresponding Convolutions and Fissures, and this willmaterially assist the reader in his comparison of the differentforms. The explanations of these references are given by Owen(loc. cit., vol. iii. pp. 136, 137), where the Fissures and Convolutionsof Mammalia are enumerated mainly in their order of outline figures of
