Contagious and Epizoohc Diseases. 1 1 



York, (Connecticut,) New Jersey, Delaware, Pennsylvania, 

 Maryland, Virginia and District of Columbia. This ought 

 to be rooted out by measures executed by the central goT- 

 ernment and defrayed out of the public treasury. Little 

 good must be looked for from isolated action by States, 

 counties, townships, or individual owners ; the danger 

 threatens the entire country, and for the general safety all 

 must pay. It is absurd to expect the unfortimate possessor 

 of sick animals to beggar himself for the pubhc good. 

 There should be destruction of the sick, partial remunera- 

 tion of the owners, thorough disinfection under professional 

 supervision, and the most perfect control and constant in- 

 spection of all suspected herds and places until the malady 

 has been eradicated from the land. This is the most in- 

 sidious of all our animal plagues, the one which now most 

 urgently presses for active interference, and which, if neg- 

 lected, will bring a terrible retribution in the future.

 swellings and formations of matter between the bones of

 irritation of teething, and, above all, change of locahty and 

 cHmate. Eepeated attacks wiU occur in the same horse 

 under the influence of the last named cause. Exposure 

 to cold and wet, impure air, sudden thaws, etc., contribute 

 to hasten its development. Lastly, contagion is a com- 

 mon cause, and, in some cases, the malady may even be 

 conveyed to man. 



Symptoms. The disease is often preceded by a period 



of unthriftiness, staring coat, loss of condition, duUness 



and. languor. Then there appear cough, redness of the 



nasal membrane, and watery flow from the nose and eyeS;
