Accessory Renal Arteries. 



In this subject there was found to be three accessory renal arteries to 

 the right kidney. Of these, two arose by a common trunk, from the abdom- 

 inal aorta, above the main renal artery. The common trunk was about \ inch 

 long. These arteries passed behind the inferior vena cava and supplied the 

 upper part of the kidney. 



Another accessory renal artery arose below the main artery. It passed 

 in front of the inferior vena cava and supplied the lower part of the kidney. 

 The main artery divided up into branches and passed into the hilus of the 

 kidney as usual. 



There were also two renal veins. One came from the upper part of the 

 hilum and the other from the lower part, and both passed into the inferior 

 vena cava.

Abnormal Omo-hyoid. 



In this case the omohyoid muscle was found to be in two distinct 

 portions an inferior portion and a superior. Both parts took origin from 

 the upper border of the scapula beside the suprascapular notch by separate 

 tendons. 



The superior band blended with the sterno-hyoid muscle about f-inch 

 below the body of the hyoid bone. The inferior band joined the sterno-hyoid 

 muscle just below its middle point and was about twice as broad as the 

 superior band. The tendinous intersection of the sterno-hyoid muscle was
