LIST OP MEDICINES. 385 



tincture of aloes, says Mr. Youatt, " is a very useful, stimula- 

 ting and healing external application to wounds. Two ounces 

 of powdered aloes and a quarter of an ounce of powdered 

 myrrh, should be macerated [soaked] in a pint of rectified 

 spirit and diluted with an equal quantity of water." 



ALTERATIVES. Ethiop's mineral, (black sulphuret of 

 mercury,) nitre and sulphur, compounded in the proportions 

 of one, two and four, is useful in the cutaneous diseases of 

 sheep. Average dose two drachms, administered daily. 



ALUM Is used in some astringent medicines, but is 

 inferior to various other articles for this purpose. It is some- 

 times employed in solution to bathe an inverted womb or a 

 prolapsed rectum. (See page 145.) Burnt alum is used as a 

 stimulant and caustic on wounds, but there are better ones. 



AMMONIA In the form of hartshorn, enters into various 

 liniments, and some other medicines. It is an excellent 

 external stimulant, and rubefacient. Internally it is an 

 antacid and sudorific, but is not often thus used in sheep 

 diseases. 



ANODYNES. Opium is chiefly employed for this purpose. 

 The modes and times of its exhibition have been pointed out 

 throughout this volume. 



ANTIMONY, (the Chloride of Butyr of.-) By far the best 

 caustic in advanced stages of hoof -rot. For the causes of 

 its superiority, and for its mode of application, see page 370. 



AQUA-FOKTIS. See Nitric Acid. 



ARSENIC. Used in solution to kill ticks and cure scab. 

 See pages 188, 341-343. 



ANTISPASMODICS. Opium is employed in the case of 

 tetanus or locked-jaw, colic, etc. 



ASTRINGENTS. Opium (acting as an anodyne,) is chiefly 

 relied on internally. Catechu frequently forms a part of 

 medicines intended to have a slightly astringent effect. Alum 

 is used in the form of alum whey 2 drachms of pulverized 

 alum dissolved in a pint of hot milk. The external astringents 

 most used in sheep diseases are a solution of alum, or a 

 decoction of white oak bark, burnt alum, bole Arminian, etc/ 



BALLS. Medicine should never be administered in the 

 form of balls to sheep. For the reasons see page 299. 



BLISTERS. Not often resoi-ted to in sheep practice. 

 When used the hair or wool must be closely shaved, and the
