I therefore, with all humility, -beg leave to offer the following experiments to the consideration of the learned. put on the third day there seemed to be as great a discharge as Experiment I. A fine fresh young horse being seized with the glanders, was turned into a salt marsh, and neglected till the distemper arrived at its greatest height, or what the farriers call the chine 488 To an old cast-off horse, blind, and troubled with the poll evil, I gave a pint (wine measure) of laurel water in the morning fasting, he having been tied up to an empty rack all night for that purpose. Just before I gave it him I took seven. ounces a drachm and a scruple of blood from the jugular vein, which was extremely viscid and foul, looking at first like coarse grease, and after it had stood some time it had a coat upon it above aninch thick, tough and horny, rather resembling one part of brawnthan buff leather. The gore was of a deep black. The serum was pellucid, but no more in quantity than six drachms. The pulse, before he tookthe laurel water *, beat 34 strokes in a minute; and indeed they were not so much accelerated by the dose as I expected, they never exceeding 45 that day. The only visible effect was stopping the humour that flowed fromhis poll; which, thoughit ran in an extraordinary manner before he took the laurel water, was quite suppressed in the evening. About two hours after he had taken his dose, I gave him some oats, which he ate greedily, and continued perfectly well all night. The next morning I let seven ounces and a drachm of blood, which, after it had stood twenty-four hours, as the otherdid , separated an ounce and two scruples of clear, straw-coloured serum. The crassamentum was something improved in its co- lour, and the horny coat at the top of it was not quite three quarters of an inch thick. The poll evil was quite shut up all this day ; and theref ore that I might know how long it would remain so, I desisted from giving any more laurel water for three days. The next morning co Experiment U1. glanders, which among themis deemed incurable. The matter which was discharged from his nose was very viscid, yellow, and extremelyoffensive. His veiceaniiney gxceeding glutinous and foul, and had a buff coat upon it more than half an inch thick. The cohesion of the crassamentum was so strong as to resist the weight of a columnof mercury, in a glass tube, with an obtuse point about the. size of a se 134 inches high, before the point of the tube cut through. The bore of the tube was one-third of an inch diameter. Eight ounces of this blood, which was taken from the jugular vein, separated, after’ standing twenty-four hours, no more than two drachms ten grains of yellow serum. : July 28, 1734. I gave to this horse six ounces of laurel water diluted with half a pint of spring water, and repeated it every morning for eight days. Aug. 5. I increased the dose to eight ounces, and continued it for eight days more. The same dayeight ounces of blood afforded one ounce two drachms of serum, not quite so yellowas before. The buff coat was three-eighths of an inch thick. The cohesion very little altered. Aug. 13. The dose was increased to twelve ounces, and repeated every morning for eight days. The same dayeight ounces of blood separated one ounce and a half of good-coloured serum. ‘The buff coat was now not above a quarter of an inch thick, and gave way to the weight of the humour began to flow again, though not so much asbefo re; ten inches of mercury. 4 Aug. 21.
