cess, indeed, there should be as little ex- 

 posure to air as possible. 



LINIMENT. A term given to external 

 applications of the oily kind, but of a con- 

 sistence rather thicker than oil. 



LINSEED. These seeds abound with oil 

 and mucilage, and are well adapted to the 

 composition of those emollient drinks that 

 are so useful in inflammations of the bladder 

 and bowels, or coniplaints of^ the urinary 

 passages. A strong mucilaginous drink 

 may be made without bruising the seeds, 

 either by decoction, or infusion. (See 

 Emollients ayid Pectorals^ Pharm.J 



LIQUORICE. An extract made from 

 liquorice root, and supposed to be of use in 

 relieving cough. In the horse it is not ap- 

 plicable to this purpose, as its good effect de- 

 pends upon its gradual solution in the mouth, 

 so as to be constantly lubricating the throat. 

 Many writers, however, recommend liquo- 

 rice in their pectoral and cordial drenches, 

 probably with a view to render them more 

 palatable. 



LITHARGE. A calx of lead employed 

 in making Goulard's extract, and diachyloij 

 plaster.
