of cold and 3 of boiling water. It is used for the same 
purpose as the chloride of barium. 
“ Properties and Uses . — Occasionally the barytic salts are 
employed in veterinary medicine, but with doubtful efficacy. 
They are nearly all poisonous, except the sulphate, which is 
harmless. The safest antidote, therefore, for the soluble salts, 
is the sulphate of soda; and in poisoning by the carbonate 
it has been proposed to use a mixture of vinegar with an 
alkaline sulphate. They give a greenish yellow tinge to the 
flame of spirit of wine, and with the exception of the sul- 
phate are all soluble in dilute nitric and hydrochloric acids. 
A saturated aqueous solution of strontia is the best for the 
salts of baryta. 
“ Mr. Percivall has recorded several experiments with these 
compounds on farcied and glandered horses ; from which it 
would seem that on which the most reliance, if any, can be 
placed, is the chloride of barium, given in doses of from 3ss 
to 5ijj and repeated in the course of the day, if found neces- 
sary. It is safer to begin with the smaller quantity, and 
very gradually to increase it ; but should inappetence be 
produced, the agent must be immediately withheld for a 
time, otherwise poisoning may result, of which he adduces 
more than one instance.”

te Put the lime first mixed with the water into a retort, and 
to these add the spirit, that the mixture may fill only the 
third part of the retort. Then heat in a sand bath : and 
when ebullition first commences, remove the fire as quickly 
as possible, lest the retort be broken by the suddenly in- 
creased heat. Let the solution distil into a receiver as long 
as there is nothing which subsides, the fire being restored if 
it be at all needed. Add four times as much water to the 
distilled liquid, and shake all well together. 
“ Cautiously separate the heavier part as soon as it has 
subsided, and to this add the chloride, and shake occasion- 
ally during an hour ; finally let the fluid again distil from a 
glass retort into a glass receiver.
