250 THE IMPROVED ART OF FARRIERY. 



at. It may be further remarked on it that here also 

 some symptoms are mistaken for original and distinct 

 diseases, among which stands the old affection of the 

 mouth called lampas. 



Lampas is a symptom of that derangement of the 

 stomach and its recipient passages which sometimes 

 follows, and sometimes precedes, the binding of the 

 hide, an unthrifty and staring coat, &c. &c. Its treat- 

 ment must therefore fall under the remedial plan de- 

 tailed for the removal of morbid condition. 



Ragged Teeth. ---Not unfrequently in old horses the 

 teeth become unevenly worn, and now and then actually 

 decayed, in w^hich cases, as they grind the food less 

 minutely, so they rob the animal of a portion of his 

 nutriment, and thus injure his condition. 



Crib-biting. — This likewise proceeds from a deranged 

 state of stomach, and is therefore a frequent, though 

 not a constant companion, to the other symptoms 

 of defective condition. 



The morbid change which takes place in the aU- 

 mentary canal in the state called " out of condition," 

 is not sufficiently defined, and whether it be a diseased 

 state of structure in its surface, or whether it arises 

 from a vitiation of the secretion of the parts, is not al- 

 together clear. If we argued from some appearances 

 which occur, as the swollen state of that cuticular por- 

 tion of the alimentary canal which lines the mouth, 

 called lampas, and the thickened state of the cuticle 

 of the tongue also, we should be led to infer a diseased 

 alteration in the cuticular lining of the canal through- 

 out. I have also observed in two instances which oc- 

 curred of horses having been accidentally killed, both 

 of which were very much out of condition, that the 

 cuticular portion of the stomach was relaxed and 

 streaked with inliamed marks nor w^as the secretjng
