Domestic Encyclopædia (1802)/Warbles
WARBLES, in farriery, are small, hard tumors arising on a horse's back, and generally occasioned by the heat, or friction, of the saddle in travelling.
As these injuries frequently occur in horses, after hard journies, or a severe chase, we would advise every person to whose care these noble animals are entrusted, minutely to examine the back every time when the saddle is removed. If any hardness or inequality should be perceived, from which a warble may probably ensue, the affected part must be bathed with the following liniment, that alone will be sufficient to check the progress of the swelling: Take of extract of lead, half an ounce; camphorated spirit of wine, two oz.; soft water, half a pint. Previously to adding the water, the extract and spirit should be well shaken, so that they may be duly incorporated.
