Horfes, or Beafts with dry Meat, drink as much cold Water as they can at once, if they be permitted twice a-Day, or oftener, which is the only Alloy they have to condense the Steam, contract the Stomach, and give an Opportunity to the Glands in the Stomach and Guts to fill with Juices. A moderate Quantity of cold Water, or other weak Liquor, doubtless condenfes the Steam, and makes the Stomach contract, but the Parts of Water are fo light, that unless one take a very great Quantity, the Heat of the Body in a fhort Time takes off the Cold, and raifes a Steam before any great Quantity of the Juices can be fecreted into the fmall Veffels and Glands, and thence into the Stomach, and repels the Blood, and extends the Stomach. But when the Body is very hot, the Steam high, and the Juices very thin, and little remaining in the Stomach, if one drink a confiderable Quantity of cold Water, it wholly condenfes the Steam in the Stomach, and perhaps fome may pafs down into the Guts before the Pilorus can fhut, and it will abate the Strength of the Steam ifluing out of the Guts, fo far, that immediately that which perfpires will fick

And nothing will fufficiently change the Conftitution of the Blood and Juices, but a conftant Diet, which will let the Stomach contract, the Juices come in, clog, alloy, and discharge them downward, and fupply the Blood with fresh cool Juices.

The natural Efforts made by the Agents to remove the Matter which offends or obfructs, and to prevent too great Emiffion of the Juices outward or inward; in short, to keep every Thing in Order, and to repair every Thing which is out of Order.

When Phlegm increafes, it ftraightens the Paffages, and flops the Salts to diffolve it.

When the Steam drives the Blood with too great Force, thins it too much, and makes too great Secretions, it extends the Bloodveffels, and ftraightens the Glands.
