is 3 inches long, 3^ twelfths in diameter, very slightly dilated at the

The trachea is 2 inches 5 twelfths in length, its diameter 1^ 

 twelfth, gradually diminishing to 1 twelfth. The contractor muscles 

 are both anterior for the length of 1^ inch, beyond which they become 

 lateral, and terminate in the sterno-tracheal at the distance of 2 twelfths 

 from the bifurcation. There are no inferior laryngeal muscles. The
