When you do administer a Glister, you shall set the Horses hinder parts somewhat higher then the foreparts, and then you shall put the Glister-pipe in at his Tuel into his Fundament up to the head, and having the confection within the Bladder, wring it with a very good strength into his body. A Glister would be administred to a Horse when he is rather empty than full paunched, whether it be in the fore-noon or after-noon. Now for the retaining or holding of the Glister in the Horses body, three quarters of an hour is sufficient, of what quality soever it be. Now you are to note by the way, that as soon as the Glister is administred unto the Horses body, you must draw out the Pipe with all the gentleness that may be, and suddenly clap his tayl to his Tuel, and so hold it with your hand, without any moving or stirring of the Horse, till the Medicine hath his full time of working.
