462 NAVIN ON THE HORSE. 



Epsom Salts. — This medicine is too well known to need de- 

 scrij^tion. It is given as a physic, in half-pound doses, as a 

 drench. It is sometimes used in the commencement of fevers, 

 in doses of six or eight ounces, and repeated. But it is not 

 equal in such cases to a dose of podophyllin, and, should the 

 case prove to be inflammation of the lungs, would be much 

 more likely to do mischief. 



Extract of lead, or GoiilarcVs extract, is the subacetate of lead. 

 It is much used in Europe for inflammation of the eyes, in the 

 early stage, in proportion of a dram to a pint of water. Twice 

 as strong, it forms a good application for inflammation not 

 deeply seated, and is good, mixed with poultices, for inflamed 

 and painful parts. 



Galls. — The gall-nuts are parasites growing on the leaves of 

 some species of the oak. They are astringent, and useful in 

 scours, overphysicking, or wherever an astringent is required. 

 The dose is from two to four drams of powdered galls, given 

 in water. Tannin is now generally used in place of galls. 

 The dose of tannin is twenty to forty grains in water. 



Garlic is used in the form of a sirup in hysteria, pleurisy, 

 cough, urethral gleet, farcy, indigestion, and rheumatism. 

 Dose, from one to two ounces, generally given in combination 

 with other remedies. It is antisj^asmodic, expectorant, and 

 alterative. 



Gentian. — The root of the plant is the part used. It is 

 found in the solid form, or pulverized, in the drug-stores. It 

 is the principal tonic used in the treatment of the horse. It 

 improves the tone of the stomach. It is generally given with 

 chamomile, ginger, or carbonate of iron. It is used in chronic 

 debility, and also debility following protracted disease. The 

 dose is from- two to four drams, repeated daily. A strong 

 infusion .of gentian is a good application to putrid sores. The 

 tincture of gentian may be used for the same purposes as the 

 powdered root. The dose is from two to four table-spoonfuls.
