A NEW INFLUENZA. 
eyes partially closed, as though light were offensive to him, and 
with swelling of the legs commonly as well; or the complaint 
about him may be, simply that he is dull and off his feed the 
eyes and legs being as yet unaffected. Examination of the par- 
tially closed eye shews a blush of redness upon the conjunctiva, 
but in general no appearance of disease in the eye itself. When 
the conjunctival redness, however, increases into actual inflamma- 
tion, should the reflected portion of the membrane become in- 
volved, the cornea loses its pellucidity, and in some rare instances 
the inflammatory action extends into the eyeball, causing changes 
in the iris, effusion into the anterior chamber, &c. The ophthalmia, 
conjunctival in its seat, is of the nature of that denominated puru- 
lent : after the second or third day, pus is seen collected around 
the margins of the eyelids, and now and then is secreted in suffi- 
cient abundance to run over upon the cheek. Preceding the secre- 
tion of the purulent matter, in the first instance, the tears are re- 
dundant, as is evinced at the time we are examining the eye, by 
their running over upon our fingers, conveying to them the sensa- 
tion of “scalding hot.” The dropsical infiltration commonly shews 
itself in the hind legs ; either they are simply filled or they are 
tumefied. Sometimes swelling is perceptible in all four legs. 
Seldom does it attack one leg first and afterwards the others. 
Now and then, however, the swelling attacks the belly first, often is 
seen in the sheath. Sometimes upon the belly the tumefaction has 
that circumscribed isolated appearance, that induces one to think it 
is no more than a girth-gall. Commonly the sub-abdominal tume- 
faction has a soft puffy feel : now and then it is firm and solid. Sel- 
dom is the swelling of the limbs so great as to extend above the 
hocks and knees. One solitary instance has occurred of aphthous 
inflammation and ulceration of the buccal membrane, resembling to 
all appearance that which was so much complained of among neat 
cattle at the time of their epidemic. 
The vicissitudes of temperature of wet and dry have certainly 
been, this present summer, greater than we, even in our variable 
climate, are in the habit of witnessing : that these changes from cold 
and wet to heat, and vice versa, have had something to do with the 
production of the two visitations of influenza we have experienced, 
one among the young the other mostly among aged horses, we think
