 resented in black. One whole fasciculus and one fibre from an adjacent fasciculus have 

 been included, a, perimysium ; 6, endomysium ; c, a large vein seen in transection.

FIG. 71. STRIATED MUSCLE OF A CAT SEEN IN TRANSECTION. 



The blood vessels have been injected and are black in the figure. At a an artery is 

 contracted and empty. The heavy black vessels are veins and arterioles ; the small 

 black dots are capillaries in transection. One whole fasciculus is represented and is sur- 

 rounded by a delicate perimysium of connective tissue. Between the muscle fibres is the 

 still more delicate endomysium. The larger vessels are almost exclusively found in the 

 perimysium. The section was not stained, x '80.
