but, like cordials, they have been fatally abused. Many a horst 

 recovering from severe disease has been destroyed by their too 

 early, or too free use. The veterinary surgeon occasionally ad- 

 ministers them injuriously, in his anxiety to gratify the impa- 

 tience of his employer. The mild vegetable tonics, chamomile, 

 gentian, and ginger, and, perhaps, the carbonate of iron, may 

 sometimes be given with benefit, and m,ay hasten the perfect reco- 

 very of the patient ; but there are few principles more truly found- 

 ed on reason and experience, than, that disease once removed, 

 the powers of nature are sufficient to re-establish health. Against 

 the more powerful mineral tonics, except for the particular pur- 

 poses that have been pointed out under the proper heads, the horse 

 proprietor and the veterinarian should be on his guard. 



Turner's Oerate, — see under Digestives, and also under 

 Zinc. 



Turpentine. — The common liquid turpentine has been de- 

 scribed as one of the best diuretics, in doses of half an ounce, and 

 made into a ball with linseed meal and powdered ginger. It is 

 added to the calamine or any other mild ointment in order to ren- 

 der it stimulating and digestive, and, from its adhesiveness and 

 slight stimulating power it is an ingredient in mange ointments. 

 The oil of turpentine is an excellent antispasmodic. For the re- 

 moval of colic it stands unrivalled. Forming a tincture with 

 cantharides, it is the basis of the sweating blister for old strains 

 and swellings. As a blister it is far inferior to the common oint- 

 ment. As a stimulant frequently applied it must be sufficiently 

 lowered, or it may blemish. — See Resin.

Wax, — The yellow wax is used in charges and some plasters

Zinc. — The impure carbonate of zinc, under the name of 

 Calamine Powder, is used in the preparation of a valuable heal- 

 ing ointment, called Turner's Cerate. Five parts of lard and ont 

 of resin are melted together, and when these begin to get cool 

 two parts of the calamine, reduced to an impalpable powder, ar<3 

 stirred in. If the wound is not healthy, a small quantity of com 

 mon turpentine may be added. This salve justly deserves thd 

 ..■•ine which it has gained, " The Healing Ointment." The ca- 

 i amine is sometimes sprinkled with advantage on cracked heela 

 and superficial sores.
