THOUGHTS ON INFLUENZA. 
granules, floating in a thin mucus, flow slowly down the 
nostrils. In cases so far advanced as this I have allowed the 
patient perfect liberty in the straw-yard ; when, after turning 
round several times like a dog, he lies down, and, giving some 
few groans, expires. 
In some young, robust animals, tumours form under the 
lower maxilla, and suppurate tardily. In others, abscesses 
exist in the guttural pouches, which is the most frequent 
kind of suppuration. But in whatever form influenza shows 
itself, the lungs, upon auscultation being resorted to, will be 
found to participate. If the pulse be appealed to, either 
oppression, or other signs of debility, will be clearly shown. 
The respiration may seem to be undisturbed, but if the 
attentive observer stand a little behind and on one side of 
his patient, he will observe that a peculiar motion of the 
flanks is visible, and a long line of constriction or “ tucking 
up” extends from the flank to the sternum, corresponding to 
the lower margin of the obliquus externus abdominis. This 
is done to render the ribs a fixed point, and to mitigate the 
friction within the chest, and it may be present on one or 
both sides. Upon applying the ear, the sound of the heart 
beating may be heard like a dull heavy thump, having a 
peculiar vibration, indicating effusion ; or it may be altogether 
inaudible from complete congestion or hepatization of the 
lungs. Percussion fully ratifies these conclusions. Effusion 
sometimes takes place within the pericardium, giving rise to 
an intermittent pulse ; then the lungs seem only to partici- 
pate partially, but pleuritic tenderness is clearly demonstrable 
both by the abdominal constriction and on slight pressure being 
applied ; also by the careful inspirations and the groans made 
in turning. When the breath is extremely fetid, one or 
both the lungs may furnish the cavernous rale . I have met 
with it in several cases which have been of long standing and 
neglected. 
During the time in which I have particularly noticed this 
disease, in this district, I find iC strangles” in young horses 
has either been greatly modified in its character, or, in the 
majority of cases, has given place to it, and, as it were, becom- 
ing latent, developed itself at a distant period in a more viru- 
lent form of influenza, in which the greatest debility exists. 
Suppuration tardily takes place in the submaxillary glands, 
or guttural pouches, the shoulder, rectum, groin, mesentery, 
or thorax ; or, in fact, it may prove to be glanders. 
In those animals which have died from that form of 
constipation already noticed, and when coma was present to a 
greater or less extent, clots of venous blood have been found
