    about eight weeks after being placed on this food. The deaths continued through a period of thirty-nine days. During this period 154 died in the pen of 624. The average death rate per day during this period was 3.95. The first fifteen days it was five per day; the next eleven days, 6t\ per day, and the last eleven days, \\ per day. Percentage that died, 24-]^. Post mortenis were made in fifty-eight cases, taken indiscriminately. Oct. 25, 1858. Another lot of 404 hogs, just driven in from the surrounding country, where they were purchased from farmers, were placed in another pen, and put upon the slop from the whiskey distillery. This slop is the residue from the steam stills, after distilHng off the high wines. It is always very sour, from the presence of acetic acid (vinegar), and is filled with alcoholic and vinegar yeast (saccharomyces cerevisiaB, and mycoderma aceti). These hogs were all in the finest and healthiest condition, and would average in weight 170 to 180 lbs. each. By way of explanation, I will here state that each bushel of corn produces about forty gallons of slop. Each gallon of slop contains about four drams of acetic acid. Of the TStVtt per cent, of nutritious matter in corn, all is used up in the process of whiskey-making (alcoholic fermentation), but 12tc?o per cent., which is itself partially decomposed. This renders the slop worth for fattening purposes, less than h or \ that of the grain. When the hogs are on full feed, each hog is allowed eight gal- lons per day. During the first eight weeks, however, the new hogs are kept on short feed, and are only allowed five gallons each per day. Oct. 25. Fed ravenously. Wanted more feed than was al- lowed them. Oct. 26 and 27. Feeding ravenously. Very active ; squeal- ing and tearing about the pen ; fighting and very uneasy. Oct. 28. Beginning to get costive, and bloating up with wind. Still ravenous for more food ; very uneasy. Oct. 29. Becoming quite constipated, and very much bloated. Stools hard and becoming darker and more scanty.
