NOMENCLATURE. 



The popular term &quot;murrain was applied, in times past, to all fatal cattle diseases that 

 prevailed in an epizootic form. The first satisfactory description of the lung plague, 

 written by Bourgelat, in 1769, teaches us that the malady has been known for some years 

 in Franche-Comtd, under the name &quot;murie.&quot; The expression &quot;pulmonary murrain has 

 been somewhat extensively used in Great Britain of late years, especially when reference 

 has been made to the outbreaks of the last century, which have been considered as due to 

 the simultaneous introduction into the British Isles of the Steppe murrain, commonly 

 known as the rinderpest and cattle plague, and contagious lung disease. 



When free trade first admitted continental cattle and the lung plague into the British 

 Isles within this century, the dairymen who first observed the new fatal foot and mouth 

 disease at once became alarmed at the &quot;new disease,&quot; which proved incurable. Professor 

 Hertwig, of Berlin, and correspondents of agricultural papers, soon enabled our veterina 

 rians to recognize in the &quot;new disease&quot; the Lungenseuche, or, literally, lungs plague of 

 cattle, which had been studied with great ability by the veterinary surgeons of Germany. 

 Haller had termed it Viehseuche, and expressed his astonishment that it had not been 

 recognized as a disease of the lungs. 



German writers were so numerous that attempts were not rare to give a scientific 

 name to the disease, and Sauberg quotes seven Latin sentences employed by different au 

 thorities in accordance with the views of the nature and origin of the disease. They are : 



Peripneumonia pecorum epizootica typhosa Veith, Tscheulin, Burger. 



Peripneumonia exsudativa contagiosa Rychner, Van Hertum. 



Peripneumonia exsudativa enzootica et contagiosa Gielen. 



Peripneumonia n. pleuropneumonia pecorum enzootica Dieterich, Vix. 



Pleuritis rheumatico-exsudativa Wagenfeld. 



Pleuropneumonia interlobularis exsudativa Gluge. 



Pneumonia catarrhalis gastrica asthenica Naumann. 



Haller s title of Viehseuche is now almost always restricted to the Russian murrain, 

 and the name in universal use in Germany is the popular one of Lungenseuche, and on 

 the title-pages of monographs the ordinary expression employed is Lungenseuche des 

 Rindviehes. It has, however, also been termed Lungenfdule and Krebsartige Lungenfdule. 



Of the French authors, Chabert first names the malady Pcripneumonie, ou Affection 

 gangrcneuse du poumon. Huzard describes it under the head Pcripneumonie chronique, 

 ou Phthisic pulmonaire, and in 1844 Delafond designated it Prripneumonie contagieuse du 

 gros betail. 



The Dutch called it Kioaadaardige Slijmziekte, Heerschende or Besmettelijlce Long- 

 ziekte, Slijmziekte, Slijmlongziekte, and Rotachtige Longziekte. 



In Italy it has been known by the names Pulmonea dei bovini, and Pleuropneumonia 

 essudativa.
