REPORTS ON THE INFLUENZA 
It is impossible to ascertain the precise number that died in 
the colony, but it was considerably more than seven thousand. 
The character of the runs upon which the sheep fed was that of 
lofty ranges abounding in excellent pasturage and' good water. 
The sheep, it may also be remarked, had depastured in the same 
locality for five or six years, and remained perfectly healthy. 
When the sheep were first attacked with the disease they were 
removed to another run, without any diminution of the severity 
of the disease. 
Symptoms. 
The first observation I had of this disease led me to divide it 
into three stages ; but as I wish to impress on the mind of the 
reader the importance of selecting and treating the sheep in the 
first stage of the malady, it may be of consequence to remark, 
that a careful observer may distinguish a sheep attacked by the 
disease nearly 36 hours before its ceasing to feed, by sneezing, 
and before it has exhibited any of the more marked symptoms 
which are placed under the first stage of the disease. 
The disease commences with sneezing, more particularly at 
night, followed by general lassitude ; and although at first the 
secretion from the nostrils merely bedews the surface, yet it soon 
becomes of a thick glairy consistence, and is secreted in a large 
quantity. The interior of the nose at this stage exhibits but 
little increase of vascularity. The eyes are suffused, and in some 
instances there is a profuse discharge of tears ; in others, again, a 
discharge of matter from the meibomian glands is also observed, 
encrusting the eyelids. The animals cease to ruminate, and 
droop the head. In some the respiration is affected as soon as 
the attack comes on. The tongue is parched, the secretions are 
diminished, except in the inflamed membranes ; perspiration is 
obstructed, and general fever accompanies the attack. A rest- 
lessness is also perceived in the animals. 
As the disease advances to the second stage, which varies in 
duration from four to twelve hours, all the foregoing symptoms 
increase in violence. The interior of the nose exhibits a 
florid hue, as if all the bloodvessels had been filled with minute 
injection ; the secretion from the nostrils now becomes thick, of 
a yellow colour, and frequently hardens upon the orifices of 
the nostrils, impeding respiration. 
The general fever is much increased ; there is suppression of 
urine in many cases ; costiveness is also occasionally observed, 
but is far from being general. The tunica conjunctiva of the eye 
displays an inflammatory character. There is a heaviness in 
the head, and an apparent desire on the part of the animal to
