The "Twenty-ninth Annual Report of the Cincinnati Price Current," published while the author has been writing this chapter, shows what our country can do in supplying meat for foreign as well as home markets. The states of Ohio, Indiana, Illinois, Iowa, Wisconsin, Michigan, Minnesota, Nebraska, Missouri, Kansas, Kentucky, and Tennessee, contributed to the packing establishments between November 1, 1877, and March 1, 1878, during the winter season of six months, 6,505,446 hogs; and during the summer season, from March 1 to November 1, 2,543,120 animals,--making a one year's total of 9,048,566 pigs, which averaged a net weight, when dressed, of two hundred and twenty- six pounds. Thus the weight of meat alone packed in one year was 2,044,975,916 pounds. Add to this the crop of California, Oregon, and Canada of the same year, and the total swells to 12,301,589 hogs, duly registered as having been killed by the pork-packers, and there still remain uncounted all the pigs killed in thirty-eight states by farmers for their own and neighbors' consumption. This annual crop of pork a jocund professor once described as "a prodigious mass of heavy carburetted hydrogen gas and scrofula;" but the chemists of our day would more properly stigmatize it as a vast quantity of Luzic, Myristic, Palmitic, Margaric, and Stearic acids in combination with glycerine and fibre. A western savant, having investigated the parasites existing in hogs, affirms that in western pork, eight animals out of every one hundred are affected by that muscle-boring pest so dangerous to those who have eaten the infected meat, and so well known to all students as the Trichina spiralis. The distinguished writer Letheby says of this parasite: "As found in the human subject (after death) it is usually in the encysted state, when it has passed beyond its dangerous condition, and has become harmless. In most cases, when thus discovered, there is no record of its action, and therefore it was once thought to be an innocent visitor; but we now know that while it was free, (that is, before nature had barricaded it up in the little cyst,) its presence was the cause of frightful disorders, killing about fifty per centum of its victims in terrible agony. The young worms having hatched in the body of man, migrate to the numerous muscles, causing the most excruciating pain, so that the patient, fearing to move his inflamed muscles, would lie motionless upon his back, and if he did not die in this state of the disorder, nature came to the rescue and imprisoned the creature by surrounding it with a fibrous cyst, where it lives for years, being ready at any moment to acquire activity when it is swallowed and released from its cell."
