which were covered with similar round-shaped bodies, of 
various sizes, and having also a whitish-yellow colour. No 
true adhesion, however, existed between the mucous mem¬ 
brane and these deposits. 
The layers of pseudo-membrane, with their rounded masses, 
presented at certain spots on their surface a coating of a 
dark-green colour,varying in some places to a pale green. On 
examining this by the microscope it was found to be composed 
of Mucedinece , designated by botanists the Aspergillus glaucus. 
Second Observation. — The pathological specimen of this 
case was sent by M. Poelman. It consisted of a portion of 
the trachea of an ostrich. It had been kept for some days 
in alcohol, which had somewhat altered its original condi¬ 
tion. The trachea presented nothing abnormal in its upper 
portion, excepting a yellow spot of about half an inch in 
length. This spot was covered with a layer of mucus, 
which had been coagulated by the effect of the alcohol. It 
was found to be placed in the mucous membrane, and to 
have in the centre of its exposed surface a small excavation. 
Concentric zones, limited by a margin, covered the surface. 
The inferior half of the trachea had a more singular appear¬ 
ance. It was filled with a quantity of yellowish matter, which 
was intermixed with coagulated mucus, probably from the 
effect of the alcohol. There were also some foreign bodies pre¬ 
sent, having an appearance like the remains of the grains which 
had been taken as food by the bird. This yellowish sub¬ 
stance was found in greater quantity in the bronchial division 
of the tube, which was here nearly obliterated by its pre¬ 
sence. At first sight these deposits did not appear to have 
any particular shape, but on a closer inspection it was 
found that an initial form presided in the development of 
each of them. The smallest spots had the form of a disc, 
were somewhat convex on their upper and excavated on 
their inferior surface, corresponding with the mucous mem¬ 
brane, with which it only formed a slight adhesion. The 
larger spots presented a ragged appearance superiorly, 
which seemed to arise from the layers being superimposed 
one on the other. On attentively examining the specimen 
by the mcroscope, it was found to be of the same nature as 
one previously described. 
Third Observation .—The subject of this investigation was 
furnished by M. Poelman. The morbid product was found 
in the respiratory organs of an ostrich. We omit the details, 
which are a repetition of the others. The microscopical ex¬ 
amination gave the same results as in the former cases.
