DISEASES OP SHEEP. 21 



prominent kinds of such issues are, — Diffusion, Suppura- 

 tion, Ulceration, Exudation, Callosity or Hardening, and 

 Gangrene or Mortification, which are described as follows : 



1st. Diffusion. This issue of an inflammation is the 

 most desirable and beneficial, and in almost every case the 

 consequence of prompt and suitable remedies. 



2d. Suppuration. Whenever a diflfusion of the inflam- 

 mation does not occur, and the latter continues with more 

 or less vehemence, suppuration will probably and generally 

 take place. Suppuration consists in the formation of a 

 fluid, which in the beginning is of a thin and watery ap- 

 pearance, but afterward changes into a fluid of a slimy and 

 stronger consistence, without any remarkable smell, and in 

 appearance like cream. The secretion of the inflamed 

 part occurs either upon the surface or at the bottom of the 

 same, and produces, whenever a larger amount of secretion 

 takes place, the so-called boils or an abscess. All parts of 

 the body are not in the same measure inclined to suppura- 

 tion, although there is scarcely any part which under cer- 

 tain circumstances cannot be aflTected with suppuration. 

 The liver, spleen and muscles are very seldom affected with 

 suppuration, whereas the upper skin, the cellular tissues, 

 etc., very easily begin to suppurate. Suppuration is either 

 produced by transformation of the fluids (such as blood, 

 fibrous matter, etc.), which enter into the inflamed parts or 

 is otherwise a secretion of the so-called carbuncles. 



3d. Ulceration. This represents another kind of suppu- 

 ration, the former being of a mild nature, whereas ulcera- 

 tion is of a malignant character ; for this reason the latter 

 is sometimes called " malignant suppuration." This is 

 always the consequence of an inflammation. It consists in 

 a sore, from which a certain fluid matter of a fetid smell 

 emanates. Instead of healing, the sore changes into ulcera- 

 tion by constantly enlarging upon and destroying the
