appear that there is anything essentially characteristic in the 

 constitution or temperament of the horse which renders it 

 inevitably certain that all shall be affected with the disease, 

 nor yet that it is necessary for his future development or 

 vigorous health, added to which is the consideration of deteri- 

 oration and loss attendant on an accession of strangles and 

 the possibility of its propagation by contagion, it is assuredly 

 a more rational procedure to put in force all preventive 

 measures with a view to mitigate its severity or circumscribe

 and intrinsic which may operate as predisposing influences, 

 attention ought to be bestowed on the protection of the 

 healthy from such agencies which, from their relation to, or 

 association with, the diseased, may be considered capable of 

 inducing it, as removal of the actually suffering from amongst 

 the healthy, abstaining from using the same utensils in con- 

 nection with both, and thoroughly cleansing and disinfecting 

 stables and furnishings where the diseased have been located 

 ere healthy animals are permanently or temporarily placed 

 there.

Synonyms. — Malleus, Equinse Apostimatos, Malleus Humidus, 

 Maliasmus, Farcinnia, Farcina equi, etc. 



Definition. — A specific contagious disease of a malignant 

 type, the spontaneous origin of ivliich has not been demon- 

 strated. In the horse, the specific effects of the implanted 

 virus are shown on the nasal mucous membrane, from which an 

 aqueous, viscid or purulent fluid is discharged, and on which 

 chancre-like sores are formed. The mucous membrane of the 

 sinuses of the head, the larynx and trachea, as also the lung- 

 tissue, are specifically affected. There may also be a general 

 or local inflammation of the lymphcdic vessels, lymphatic 

 glands and skin, with a tendency to form small circumscribed 

 tumours, knoivn as farcy buds or buttons, u'hich gradually
