AMONG SHEEP IN NEW SOUTH WALES. 
557 
Report by W. Sherwin, Esq. 
The first authentic account I can obtain of the existence of 
the disease in this colony is that of its appearance, about twelve 
months since, among some flocks at Burrowa; but I have every 
reason to believe that it appeared upwards of two years before 
that time at Limestone plains, and about Mudgee. 
Symptoms. — First, The diseased animal separates from the 
flock, appears listless, the eyes are watery, the membrane lining 
the nostrils presents (instead of the pale pink hue of health) an 
increasing redness, which afterwards becomes streaked with lines 
of a deeper colour; a glairy clammy discharge, similar to the 
white of a fresh egg, is perceptible in one nostril (generally the 
left), and sometimes, though rarely, in both. 
Secondly, The eyes become reddened and more watery, the 
membrane of the nose of an intense florid hue, the discharge is 
thicker, and of a yellowish tinge, and the internal membrane, as 
well as the external surface of the nose, becomes slightly swelled : 
the breathing, if carefully observed, now appears hurried, and 
the animal seems to be in pain. 
Thirdly, The membrane of the nose now assumes a dark purple 
or leaden colour, the discharge forms a crust at the edges of the 
nostrils, the breathing is more quickened, and sometimes ob- 
structed, the lips (and particularly the upper lip), nostrils, and 
sometimes the whole face and head are swollen, the eyes are 
more and more inflamed, and there is a profuse flow of tears (in 
a few instances the eyes are closed), and death ensues, rapidly 
followed by putrescency of the body. 
Appearances after Death . — The surface of the body (in many 
instances immediately) after death is of a dark purple or livid 
hue, and the wool, contrary to what is observed in animals that 
have died in health or from most other diseases, separates on the 
slightest touch. 
Dissections . — The abdominal and thoracic viscera healthy ; the 
gall-bladder in general turgid ; the membrane lining the nose, and 
extending thence to the several sinuses of the head, highly 
inflamed. The membranes of the brain, and especially the two 
nearest the brain, also presented the appearance of previous 
intense inflammation. In a few instances there was a small 
effusion of fluid into the ventricles. In one instance, in which 
the respiration had been observed to be more than usually 
affected, the mucous membrane of the lungs was found inflamed; 
though even in this case, that part of it which lined the upper 
portion of the windpipe was the more intensely so; whence it
