deceive ilie public. From out dram to two or three 

 is a proper dose. — Corrosive sublimate and calomel 

 are the most common forms of mercury used in vete- 

 rinary medicine. — Corrosive sublimate is used in farcy 

 and glanders, and may be given in doses of ten grains, 

 increasing with caution to two scruples in desperate 

 cases, and sometimes even to much more. Calomel 

 is given as an alterative in worms ; in hide bound, 

 surfeits, and mange. The dose is from one scruple to 

 two daily ; but caution is necessary in watching it very 

 strictly ; for a horse will bear much less mercury, 

 MJthout salivation, comparatively, than a man. 



Another class of alteratives are Diureiics, which 

 act on the kidneys, and increase the flow of urine. 

 Diuretics are very uucertahi in the human subject, 

 but in the horse are very certain ; hence they are 

 Tery frequently resorted to. Those in general use are 

 resin, nitre, cream of tartar, oil of juniper, turpen- 

 tine, tobacco, foxglove, Sec. &c. — Resin is an active 

 and useful diuretic, but it simply empties the system ; 

 w hile nitre appears to cool and lessen the circulation, 

 as well as stimulate the kidneys. From two drams to 

 four of the former is a dose as an alterative ; and from 

 three diams to six of the latter. — It requires rather 

 more of cream of tartar to produce a diuretic effect. 

 — About a scruple of foxglove, and about two scruples 

 of tobacco, are necessary to produce any effect. — Oil 

 of juniper may be given in doses of one to two and 

 three drams ; and double or treble of this quantity 

 of oil of turpentine will have the same effect. 



A third very important class of alteratives are such 

 as act on the stomach, increasing its tone, called 

 Stomachics ; to which may also be referred Coi'diah, 

 as bitters of various khids, spices, malt, beer, dc.
