Cassowary New Holland. ISS 
died of inflammation of the lungs and air-cells in the bottom of 
the neck. The investing membrane was excessively vascular; 
and the lymph, effused over a very extensive surface, had as- 
sumed, as is usual, the form of a membrane. There was little 
or no effusion. The cause of death did not appear on the dis- 
section of the New Holland Cassowary. It will be readily ima- 
gined^ that I did not even attempt to look at the nervous sys- 
tem, since the only parts which came properly under my inrspec- 
tion were the viscera, cut from the back-bone, and dragged out 
through tlie abdominal cavity. 
Of the organs of sense, the only one I had it in my power to 
examine was that of vision. Many interesting appearances pre- 
sented themselves, to detail which would be foreign to the ob- 
ject of this notice, and would, moreover, interfere with a me- 
moir I am preparing on the anatomy and physiology of this 
organ. I shall therefore merely mention, that the examination 
of the eye in theGaleated and New Holland Cassowary, confirmed 
all my previous observations on the eyes of birds, the principal 
of which go to prove, that the marsupium, by some considered 
a muscle, is simply a membranous expansion reflected by the 
choroid, and quite continuous with it ; that the white lines of 
nervous matter at its base, to which so much importance has 
been attached by some, are occasioned by the dissection, and are 
not natural to the organ ; that there is a perfect analogy between 
the marsupium in birds and in many fishes ; that the annulus 
albus, or ciliary ligament, supposed by some distinguished ana- 
tomists to be a nervous plexus or ganglion, is a muscular body, 
and is principally concerned in enabling the eye to adapt itself 
to tlie perception of objects placed at various distances. 
The salivary glands have been already sufficiently described. 
The tongue, in each, is small, triangular, and has on its edges a 
number of soft projecting fringe-like bodies. The hyoid bone 
is nlso small, corresponding with the dimensions of the tongue, 
and with its comparative immobility. A true membranous crop 
can hardly be said to exist, since the gullet dilates uniformly 
until its termination in the ventriculus succenturiatus or glandular 
crop. This latter is divided, as in the ostrich, into two portions, 
viz. one possessing glands, and one without apparent secreting 
organs, placed between the former and the gizzard. The por-
