136 CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 



18. Carcasses and cadavric debris uTifit for food should be buried or so treated as to 

 become absolutely inoffeusive. 



19. Stables, fair-grouuds, markets, aud vehicles which have beeu occupied by dis- 

 eased or suspected auinuils, should be carefully cleaused, disiufected, and puritied. 

 These dift'erent operations should be under the direction of a veterinarian. 



20. A stable perfectly disinfected and purilied by eight days' free ventilation may 

 he refilled without danger. 



21. Pasturages that have been occupied liy diseased cattle should be shut up for 

 forty days at least. 



"22. Th<i different materials, objects, aud instruments that have been employed in 

 tlie slaughter, transportation, and burial of diseased or suspected animals should l>e 

 destroyed or thoroughly disinfected. Forage aud litter should be utilized for horses 

 and other solipedes. 



23. Persons who have become soiled by infecting materials should wash their hands, 

 brush or wash their clothes, and wash their boots with a disinfectant solution. 



24. All persons and animals capable of carrying the virus should be, as far as possi- 

 ble, kept from disea-ed animals, their carcasses, aud cadavric debris.* 



2.5. Indemnity should be accorded : 1. For animals slaughtered officially. 2. For 

 those that have died from inoculation. 3. For dirtVi-ent ol.yects or instruments of 

 ■which the destruction is judged necessary. 



26. Very heavy penalties should be imposed on persons who violate the different 

 sanitary regulations ordered by the authorities. 



27. A good organization of the veterinary service is the best guarantee of the ap- 

 plication of the dift'erent measures prescribed. 



28. A last and potent measure for securing the extinction of contagious pleuro-pneu- 

 monia consists in adopting a provision for the contagious diseases of animals as has 

 beeu done for the phyloxera of the vine ; to formulate an international agreement, in 

 which shall beindicated the essential elements which ought to form the basis of the 

 legislation to be adopted by each country which shall join it. 



Degive justly accorded to lung plague a principal place among the 

 plagues which are most detrimental to agriculture aud the public wealth. 

 In enumerating its anatomicallesionshe lays stress on the inliammatory 

 action being especially provocative of exudation into the interstitial 

 connective tissues of the lung — interlobular, perivascular, interalveolar, 

 and subpleural — upon the prominent implication of the lymphatics, 

 upon the great extent of lungs involved even when the general symp- 

 toms of illness have only just appeared, upon the presenceof lesions of 

 different ages, implying a long standing and a slow and occult progress 

 of the disease, and the existence in the exudate of the specific micrococ- 

 cus of Willems, Bruylant, and Verriest. (Strangely enough, he fails to 

 emphasize the infarctions and encysted sequestra which are so charac- 

 teristic of the affection.) Under the head of physiological characters, 

 beside the general synjptoms of fever and inliammation of the lungs, he 

 lays special stress on the two types of the disease, rapid and slow, the 

 latter remaining insidious, hidden, and apart from indications furnished 

 by auscultation and percussion, hardly recognizable throughout its 

 entire course; on the mortality averaging 30 per cent. ; on the infectious 

 property, very variable in different cases, but always highly conclusive 

 wheu well marked. He seeks to establish a theory of spontaneity from 

 the facts that in many cases contagion cannot be traced, that Oiawitz, 

 Greenfield, and JJuchuerhave cultivated pathogenic fungi and bacteria
