THE EAR AND IT’S WONDERS.

The External Ear. – the organ of hearing consists of three parts: the external ear, the middle ear or tympanum, and the internal ear or a labyrinth. The external part of the air represented in the colored engraving is very realistic of that essential appendage to this important special organ of sense and man. It consists of an expanded sheet of cartilage, folded and true trumpet fashion, for collecting the sound waves in conveying them to the external meatus or mouth of the auditory canal.

It probably took me about 4 tries to get my voice recognition program to pick up on the word tympanum and get it spelled correctly!  That software has been one of my best buys ever, but it still makes mistakes on weird words from time to time.
