heaving, or symptoms of broken wind, or heaves in horses. 

 It will be needless for me to say, that if the lead is not

 Poisoning.) 



(1.) Oxide of Lbad. — This preparation of lead is 

 used in the manufacture of common sticking plaster, or 

 Diachylon. 



(2.) Iodide of Lead. — (See Iodine.) 



(3.) Acetate of Lead. — Sugar of Lead. Solution of 

 acetate of lead is known by the name of Goulard's Extract 

 of Lead, and was formerly, and is still by some persons 

 recommended, and used in cases of sprains, and as a wash 

 for diseased eyes. Better and less injurious agents are 

 now used by the educated veterinary surgeon. 



Observe. Goulard's Extract, or lead-water, should never 

 be used in diseases of the eye, as it can do no good beyond 

 what cold water can do, but it dulls the eye, by making it 

 hazy and opaque. It will be well to remember this, and 

 act upon it, not minding what old and antiquated books 

 and individuals may say pr think in regard to what is here 

 recommended. 



Lime. — Oxide of Calcium. 



Lime, Carbonate of. — (See Chalk.) 



Linseed, — Linwm, Usitatissimum. Ground flaxseed 

 makes the best poultice, as it is less irritable and retains 

 its moisture better than most articles in use for that 

 purpose. 



Cake Meal. — That portion which is kept after the oil 

 has been expressed from the seed, is a good feed for horses 

 and cows, given occasionally, and makes a good and much 

 ehes^per poultice than tb« most costly seed.
