The number of the dorsal vertebrae corresponds withthe number of the ribs, which in man amounts to twelve 114 shews the articulation of the xth, xith, and xnthdorsal vertebrae, and the changes of form which the centrum and K. 130 LUMBAR 4 XII apophyses present, when compared with the fourth and fifth ; (figs. 112 and 113) theparapophy-ses and pleurapophyses are short,and the hcemapophyses have disap-peared. We here see a transitionform, for blending with the ver-tebras of the loins. [§ 256. THE LUMBAR VERTE-BRA (figs. 115 and 116) are of alarger size than those in the dor-sal region ; they are five in num-ber, and have the long diameterof the centrum in the trans-verse direction ; the neural spinepresents a considerable surfacefor the tendinous attachment ofthe muscles of the back andloins ; tlieparapophyses are short,
