VETERINARY MATERIA MEDICA. 641 



Lead. — Several preparations of this metal enter into vete- 

 rinary practice. The principal of these is the 



Lead, Acetate of {Superacetas plumhi). — This is still 

 familiarly known by the old term of sugar of lead ; origi- 

 nally so called from its sweet taste. It is of much im- 

 portance in veterinary practice, forming a more conve- 

 nient, and we think a more efficacious, mode of making 

 Goulard water, as the solution of it is popularly called ; 

 but which liquor has been usually made from a prepara- 

 tion of litharge, called extract of saturn, or Goulard's 

 extract. When this celebrated liquor is to be made from 

 the acetate, do it as follows : 



Goulard luater. — Take acetate of lead, one drachm to 

 two, proof spirit an ounce, soft water a pint : when the 

 extract is preferred, it is thus made : — Liquid acetate of 

 lead {liquor plumbi acetatis) , one drachm to tw^o ; proof 

 spirit an ounce ; soft water a pint. Either of these pre- 

 parations of the acetate of lead are excellent, and justly 

 appreciated applications, in superficial inflammations ; 

 but, to produce the full effect, the part affected should 

 be kept constantly wet with one or the other of them. 

 Liternally, this preparation is inert: even four ounces 

 have been given without producing any visible effect. 



Lead, Carbonate of {Plumbi carbonas). — White lead is 

 sometimes used as a desiccative, being sprinkled over a 

 sore. 

 Lime is, in some cases, when quick, a useful caustic ; and, 

 when pulverized, is found good to sprinkle over cankered 

 feet, greasy heels, or any foul surface, where an absorp- 

 tion of moisture, as well as an escharotic process are de- 

 sirable. 



Lime Water. — Six pounds of lime, infused in two gal- 

 lons of water, may, after standing three or four hours, be 

 strained off, and kept in a closely stopped bottle for use, 

 without which care it will be useless. Lime water is a 

 good application for mange ; and is also sometimes recom- 

 mended internally for obstinate coughs and nephritic 

 complaints. 



Chloride of Lime is a most valuable disinfectant : it 

 is used as an external appUcation to wounds having a 

 putrid tendency ; in the latter use it is inferior to the
