vessels to the kidney. The right renal artery gives oS renal, 

 suprarenal and capsular vessels, but no parietal nor ovarian 

 arteries. 



Ovarian Arteries : — The left one comes from the left renal 

 artery, but the right one springs from the aorta. Both run as in 

 Man, and their terminal parts are convoluted. 



Lumbar Arteries : — Four single arteries arise from the back of 

 the aorta. The liighest is level vi^ith the coeliac axis, the second 

 is just below the renal arteries, the third is level with the third

lumbar vertebra, and the fourth is at the fourth vertebra. 

 These bifurcate, and the halves run like the lumbar arteries 

 in Man. 



The common iliac arteries diverge for one and a half inches 

 from the aorta,, along the pelvic brim, and each gives off the 

 hypogastric artery and is continued as the external iliac artery. 

 The left vessel is the more vertical. 



The extei-nal iliac arteries give no branches, but those which
