CAUSTICS 



Are substances which burn away the living tissues of the body, by the decom- 

 position of their elements. They are of two kinds, viz., first, the actual cautery, 

 consisting in the application of the burning iron, and called firing ; and, secondly, 

 the potential cautery, by means of the powers of mineral caustics such as potash, 

 lunar-caustic, corrosive sublimate, &c. 



Firing is seldom practised on the dog, but sometimes it may be had recourse 

 to with advantage, when a very thin iron must be used. The red-hot iron is also 

 sometimes needed to stop bleeding from warts in the mouth removed by the knife > 

 or in a similar way for piles. 



STRONG SOLID CAUSTICS are as follows : 



1. FUSED POTASS. Difficult to manage, because it runs about in all directions, 

 and little used in veterinary medicine. 



2. LUNAR CAUSTIC, OR NITRATE or SILVER. Very valuable to the veterinary 

 surgeon. It should always be kept at hand in the portable wooden case made 

 specially for it. 



3. BLUE STONE, OR SULPHATE OF COPPER. May be handled safely, and no 

 case therefore is required. When used, it should be freely rubbed into the part 

 affected, It is valuable for unhealthy sores, &c. 



4. CORROSIVE SUBLIMATE is only required to remove warts, but can seldom be 

 trusted to any but a practised surgeon. 



CORDIALS 



Are medicines which act as warm temporary stimulants, augmenting the 

 strength and spirits when depressed, and often relieving an animal from the 

 ill-effects of over-exertion. 



1. CORDIAL BALLS. Powdered caraway seeds, \ to If drachms ; ginger, 20 to 

 40 grains ; oil of cloves, 3 to 8 drops. Mix. and give 10 grains for a dose. 



2, CORDIAL DRENCH. Tincture of cardamoms, \ to 1 drachm ; sal volatile, 15 

 to 30 drops ; infusion of gentian, f to 1 drachm ; camphor mixture, 1 ounce. Mix. 



DIURETICS 



Are medicines which promote the secretion and discharge of urine, the effect 

 being produced in a different manner by different medicines ; some acting directly 

 upon the kidneys by sympathy with the stomach, while others are taken up by the 

 blood-vessels, and in their elimination from the blood cause an extra secretion of 

 the urine. In either case their effect is to diminish the watery part of the blood, 

 and thus promote the absorption of fluid effused into any of the cavities, or into 

 the cellular membrane, in the various forms of dropsy.
