NEW VIEWS REGARDING ROARERS. 
membrane throughout the whole extent of the canal, including 
the bronchial tubes, presented a beautiful specimen of health, 
and, to all appearance, lubricated with the usual moisture both in 
quantity and quality. Considering that this animal possessed a 
noble thorax as to capacity, I should have had no hesitation in 
declaring publicly, that the entire respiratory apparatus, so far 
as I had then inspected it, was of the most perfect order as to 
conformation and exemption from disease. 
The jugular veins were perfect, and his throat free from glan- 
dular enlargements ; the channel between the jaws was capacious ; 
and I may add, his head was set on to the neck with elegance. I 
should have stated, that there was not the slightest ossification 
of the larynx or trachea; that I most anxiously examined every 
ring for twists or indentations, but could not detect one dis- 
placed ; till at length, chagrined with disappointment at not 
finding the jewel as well as the casket, I had the head severed 
from the neck, dismissed the carcass and attendants, and retired 
alone with the head in shame, being my only remaining chance 
and solace. 
I say shame, because I began to think how humiliating for 
an old hand like myself to be compelled to say to the scientific 
owner, “ Sir, I have ridden your horse, and 1 have dissected him 
from head to foot, but I am at a loss to tell you the seat of his 
malady, although I am bound to acknowledge its existence in a 
most decided form.” 
Now, gentlemen, you will think I have been long enough 
telling you what disease the poor grey had not got ; but I will 
very soon relate what he really had, and which is the burden of 
my story. 
I detached the lower jaw from the upper, and finding it free 
from any tumour, or projection, cast it aside. No part now re- 
mained to be explored except the face ; but here the intruder 
was secreted. 
Upon holding the head up to a strong light and looking 
through the palatine arch, I immediately detected a permanent 
obstruction in the right nasal fossa. The cartilaginous partition, 
the septum narium, was exactly in the centre, in its natural posi- 
tion and condition ; but the obstructing body was the abnormal 
condition of the right anterior and posterior turbinated bones : 
they were enormously enlarged, but, as I shall hereafter shew, 
merely dilated but not distended by any accumulated con- 
tents. 
The structure of these turbinated bones, I need not remind 
you, is very curious; they are thin bony lamellae, folded in the 
form of a turban (and hence their name), thin as gauze, perfo-
