influenza may attack the lungs themselves, causing a dull soft cough, and 

 great prostration and acceleration of the pulse ; and sometimes, though 

 rarely, the disease may terminate in mortifiration of the lung tissue itself. 

 In some epidemics, ''pleurisy,' or inflammation of the lining membrane of 

 the chest and lungs, complicates influenza, and sometimes rages under the 

 name of "epidemic pleurisy," or pleuritic influenza." Of the special forms of 

 influenza, "pink eye" is perhaps the best known, for it has been very 

 prevalent of late years. By some it is regarded as a distinct disease, but it 

 is in the writers' opinion most probably only a modified ^•ariety of simple 

 influenza. It is usually characterised by the pink colour of the white of the eyes, 

 and by great severity of constitutional symptoms and great prostration. 

 One or both lungs often become diseased, and violent diarrhoea and colicky 

 pain, indicating disease of the organs of the belly, may supervene ; and in 

 some cases there is total loss of power in the hind quarters. This form of 

 influenza is especially dang'erous in weakly animals. 



The complicated forms of influenza now recognised are three. The first 

 or the "thoracic" form, attacks the organs of the chest mainly, i.e., the lungs, 

 pleura, and heart. The second, or the "abdominal" form, or so-called 

 ^'bilious fever" or so-called "typhoid fever," attacks the organs of the belly, 

 and is characterised by great prostration, and by the yellow colour of the 

 membrane of the nose and other \isible mucous surfaces, and of the white 

 of the eye. The third and last form is termed the " rheumatic variety." 

 This form usually appears towards the close of the ordinary symptoms of the 

 disease, and is recognised by the pain in the joints, which crackle when moved, 

 and after a time swell. The heart is often attacked in this \ariety. One 

 point more we should mention as very common in influenza, and this is the 

 great liability for the glands of the throat to become inflamed and swollen, 

 and even to form abscesses. 



Influenza is a very debilitating disease in horses, as it is in man, and it is 

 to be borne in mind ' that one attack does not secure immunity from a second 

 or even a third.' 



We will now turn our attention to the consideration of the general and 

 special management of this contagious malad)-. In every outbreak of influenza 

 it should be our first object to inquire carefully into the hygienic arrangements 

 of our stables ; to see that the drains and ventilation are not at fault ; to 

 ascertain — and this is very important — whether or not the water supply is 

 contaminated with sewage matter ; and, finall)-, to see that the oats and 

 other fodder are in good condition. 



If these matters are carefully attended to, influenza will be much 

 less likely to break out in a severe and lingering form than among animals 

 subjected to defective sanitarj^ arrangements. 



In speaking of the treatment of influenza, we should always remember that 

 grave symptoms may in many instances be prevented by early and judicious 

 care and treatment. Indeed, it is certain that many a neglected case proves 

 fatal, which with proper care and attention would have pro^•ed but a simple, 

 mild attack.
