GENERAL ANATOMICAL CHARACTERS OF INFLUENZA. C9 



the lining membrane, thickened, infiltrated, and marked with 

 petechise, is observed. 



When yellowness of the visible mucous membranes has 

 been a distinctive feature of the abdominal complications 

 there is generally observed a turgid and full condition, 

 amounting in some instances to marked friabiUty of the liver, 

 incident to the congested state of the viscus and impairment 

 of its functions. 



The kidneys and other gland-structures are often changed 

 in character, hypertemic, and marked with spots of hemor- 

 rhagic effusion, or blanched, soft, and exhibiting elemental 

 tissue changes, the result of haemal vitiation and malnutrition. 



In certain instances, both in this type and in others where 

 aberration of nerve force is a noticeable symptom, we may find 

 in the membranes of the central organ of the cranium and 

 spinal canal vascular arborescence and an extra amount of 

 straw-coloured fluid. 



"When rheumatic or metastatic inflammation of the Hmbs 

 and articulations has been exhibited during life, the presence 

 of inflammatory exudation is easily enough demonstrated in the 

 thickening of tendons, the infiltration of the connective tissue 

 around and underlying the fibrous and fibro-serous membranes 

 of joints. Those cases, however, where the rheumatic form or 

 complications are most marked and characteristic do not 

 often, unless developed in connection with some other form, 

 prove fatal. 



Treatment. — In the treatment of influenza it is needful to 

 remember that the affection is essentially febrile — a specific 

 pyrexial state — and that, like all specific fevers, it has a distinct 

 and regular course, which is pursued from incubation to ter- 

 mination ; that this course may not be cut short in its develop- 

 ment, or cured, as we are apt to say ; that our object ought to 

 be the judicious guidance of the animal through the course of 

 the fever, which certainly requires to be carefully watched, 

 and complications treated as they may arise. 



In the entire management of this disease the animal physi- 

 cian will require not only to draw upon the resources of pure 

 therapeutics, but will find much benefit — in many cases of the 

 simpler forms probably more benefit — from a correct Imowledge 

 of the laws of hygiene, and from a strict enforcement of these.
