Plate 2

Figures of horseshoe and ectopic kidneys taken from the literature to illustrate Variations of renal and sex veins (legends by E. A. B.).

7 Unrotated, right ectopic kidney, from girl baby one year of age (after Schlesinger, ’24). Note fusion of two right renal veins (Fm), the distal origin of the right ovarian vein (R.ov.7;.), and fetal lobulations (Lob.).

8 Double ectopic, unrotated kidneys from a girl twenty-three years of age (after Melissinos, ’1l). Note position of diminutive right kidney on brim of pelvis, tl1e persistence of the right posterior cardinal vein (R.p.ea1'd.12.) and of the right collateral cardinal channel (I.’.coll.card.c7:..), the disappearance of the right common iliac vein (site indicated by arrow), and the origin of the right renal veins and arteries (R.ren.1m. and ac.) from the posterior cardinal vein and common iliac artery, respectively.

9 Horseshoe kidney, from a man forty-six years of age (after Ognew, ’30). Note distal origin of right internal spermatic vein (R.mI,.sp.v.) and the accessory renal branches of the iliac arteries (A(:e.ren.a.).

10 Horseshoe kidney from a man about forty years of age (after Ssokolow, ’30). Note arrangement of multiple internal spermatic veins (Int.sp.v. 1, 2,3), the persistence and Well—marked separation of both embryonic renal veins (Ren. I and II), the persistence of an intersnpracardinal anastomosis behind the aorta (1'nt.s;m*c.anast.) connecting the right supracardinal (Inf.o.c.) with the persisting left supracardinal (L.spr1;.) and renal (Re'rL.II) veins.
