the organ. A minute pointed process of the outer margin of the car- 
tilage under consideration indicates the situation of the posterior root 
of the lateral portion of the atrophied ring. The first and second 
bronchial semirings are upturned laterally, and more slender than those 
below them. The first anteriorly sends upwards and inwards a lengthy 
process of about three times the thickness of the body of the ring 
itself, cut away obliquely, so that its upper end looks inwards and a 
little upwards, nearly to meet its fellow, from which it is separated 
by a narrow triangular fibro-cartilage, developed at its base from the 
middle of the antero-inferior margin of the penultimate ring of the 
trachea. The second semiring is slightly swollen at its ends to articu- 
late with the semiring above. The interval between the penultimate 
ring and the first semiring is necessarily considerable, and is quadrate 
as well as slightly biconcave; that between the first and second semi- 
ring is meniscoid, convex upwards and shallow. The bronchial semi- 
rings below the second are peculiarly lengthy, especially the fifth, and 
pointed at the ends. Strangely also, semiring three, a short distance 
external to its anterior termination, articulates by small special facets 
with those above and below, The bronchidesmus is particularly 
strong. 
By Temminck* this windpipe is imperfectly figured.
