Tyrannosaums is ^^(f? y^<^. Fig. 93. Four Restorations of the Ostrich Dinosaur, Stnithiomimus {Ornithomimus). A. Showing the mode of progression. B. Illustrating the hypothesis that the animal was an anteater which used the front claws like those of sloths in tearing down anthills. C. Illustrating the hypothesis that it was a browser which supported the fore part of the body by means of the long, curved claws of the fore limb while browsing on trees. D. Illustrating the hypothesis that it was a wading type, feeding upon shrimps and smaller by Osbom. No satisfactory theory of the habits of this animal has asyet been advanced. an illustration of the law of compensation, first enunciated byGeoffroy St. Hilaire, first, in the disproportion between thediminutive fore limb and the gigantic hind limb, and second,in the fact that the feeble grasping power and consequentdegeneration of the fore limb and hand are more than com-pensated for by the development of the tail and the hind claws. 2l6 THE
