38 DISEASES OP SHEEP, 



ears, mouth and affected spots of the skin are of extra- 

 ordinary warmth ; the gums, tongue, aud eyes are very red, 

 hot and dry ; the breathing increased. . Toward the end of 

 the second period a clear, thin slime flows from the nose 

 and eyes, as if affected by neuralgia ; and when the lips, 

 eyelids and the head contain a great number of pox, such 

 parts are often swollen to such an extent that neither 

 mouth nor eyes can be opened. 



3. Period of maturity. — This period generally begins on 

 the tenth day after contagion, and extends until the thir- 

 teenth or fourteenth day ; in this time the indications of 

 the former period (such as the inflammatory state) diminish 

 by degrees. The pox upon the centre and apex of the skin 

 shows a fading color, the- pustule becoming of a bluish- 

 white color ; the redness disappears from the inner part to 

 the exterior ; the red circle becomes paler and smaller. 

 The upper skin of the pox separates from the bottom, and 

 between both an exudation of a clear, colorless, translu- 

 cent and adhesive fluid (the so-called lymph) takes place, 

 by which the upper skin appears as a transparent bubble. 

 During the next ten days the pox become paler, the surface 

 of the same becoming less transparent, thicker and of a 

 pale white color, the red circle disappearing entirely. On 

 the thirteenth or fourteenth day the pox arrives at its full 

 maturity or ripeness, being now of a clear white color, 

 round and sometimes of a conical form ; the upper skin is 

 very thin and of a chalk-white color, covering the so-called 

 clear lymph in great quantities, which at the opening of 

 the mortified upper skin flows in larger or smaller quanti- 

 ties. By separating the epidermis from the base of said 

 pox, the base appears of a dark red color and spongy con- 

 struction, and extends somewhat above the skin. As soon 

 as the period of maturity begins, the feverish and other 

 general indications diminish by degrees; so that after a
