a drink consists in not putting too much into the horn at once , 

 introducing the horn far enough into the mouth, and quickly turn- 

 ing and withdrawing it, without bruising or wounding the mouth, 

 the tongue being loosened at the same moment. A bottle is a 

 disgraceful and dangerous instrument to use, except it be a flat 

 pint bottle, with a long and thick neck. 



Emetic Tartar. — See Antimonio Potassio Tartras. 



Epsom Salts. — See under Magnesia. 



Ergot of Rye. — See Secale Cornutum.

Eye Lotions or Washes. — See CollyfcIa. 



Fep^rum, Iron. — Of this metal there are two preparations 

 adopted by veterinarians. The rust, or Carbonate, is a mild 

 and useful tonic, in doses of from two to four drachms. The Sul- 

 phate {green vitriol or cojyjjeras) is more powerful. It should 

 never be given in the early stages of recovery, and always with 

 caution. The dose should be the same as that of the carbonate. 

 The sulphate has lately been recommended for the cure of that de- 

 ceitful stage or form of glanders, in which there is nothing to char- 

 acterize the disease but a very slight discharge from the nostrils. 

 It is to be dissolved in the common drink of the horse. It is worth 

 a trial, but too sanguine expectations must not be encouraged of 

 the power of any drug over this intractable malady. The iron 

 should be given in combination with gentian and ginger, but 

 never with any alkali or nitre or soap, or catechu, or astringent 

 vegetable. 



Fever. — For the nature and treatment of the fever, both pure 

 and symptomatic, reference may be made to page 163. 



Forge Water, — used to be a favorite tonic with farriers, and 

 also a lotion for canker and ulcers in the mouth. It owes its power, 

 if there be any, to the iron with which it is impregnated. 



Flax Seed. — See Linseed. 



Fomentations, — open the pores of the skin and promote per- 

 spiration in the part, and so abate the local swelling, and relieve 

 pain and lessen inflammation. They are often used, and with 

 more benefit when the inflammation is somewhat deeply seated, 

 than when it is superficial. The effect depends upon the warmth 

 of the water, and not on any herb that may have been boiled in 

 it. They are best applied by means of flannel, frequently dipped 

 in the hot water, or on which the water is poured, and the heat 

 should be as great as the hand will bear. The benefit that might 

 be derived from them is much impaired by the absurd method in 

 which the fomentations are conducted. They are rarely contin- 

 ued long enough, and when they are removed, the part is left wet 

 and uncovered, and the coldness of evaporation succeeds to the 

 heat of fomentation. The perspiration is thus suddenly checked ,
