The name "the clap", in reference to the disease, is recorded as early as the sixteenth century, referring to a medieval red-light district in Paris, Les Clapiers. Translating to "The rabbit holes", it was so named for the small huts in which prostitutes worked.In 1854, Dr. Wilhelm Gollmann addressed gonorrhea in his book, Homeopathic Guide to all Diseases Urinary and Sexual Organs. He noted that the disease was common in prostitutes and homosexuals in large cities. Gollmann recommended the following as cures: aconite to cure "shooting pains with soreness and inflammation;" mercury "for stitching pain with purulent discharge;" nux vomica and sulphur "when the symptoms are complicated with hemorrhoids and stricture of the rectum. Other remedies include argentum, aurum (gold), belladonna, calcarea, ignatia, phosphorus, and sepia.Silver nitrate was one of the widely used drugs in the 19th century. However, it became replaced by Protargol. Arthur Eichengrün invented this type of colloidal silver, which was marketed by Bayer from 1897 onward. The silver-based treatment was used until the first antibiotics came into use in the 1940s.The exact time of onset of gonorrhea as prevalent disease or epidemic cannot be accurately determined from the historical record. One of the first reliable notations occurs in the Acts of the (English) Parliament. In 1161, this body passed a law to reduce the spread of "... the perilous infirmity of burning". The symptoms described are consistent with, but not diagnostic of, gonorrhea. A similar decree was passed by Louis IX in France in 1256, replacing regulation with banishment.
This is louder than a jackhammer at a distance of 1 m (3 ft 3 in). Burped speech
It is possible to voluntarily induce burping through swallowing air and then expelling it, and by manipulation of the vocal tract produce burped speech. While this is often employed as a means of entertainment or competition, it can also act as an alternative means of vocalisation for people who have undergone a laryngectomy, with the burp replacing laryngeal phonation. This is known as esophageal speech. Other animals
Many other mammals, such as cows, dogs and sheep, also burp. Ruminants
Much of the gas expelled is produced as a byproduct of the ruminants digestive process. These gases notably include a large volume of methane, produced exclusively by a narrow cohort of methanogenic archaea in the animals gut; Escherichia coli (E. coli) and other bacteria lack the enzymes and cofactors required for methane production. A lactating cow produces about 322g of methane per day, i.e. more than 117 kg per year through burping and exhalation, making commercially farmed cows a major (37%) contributor to anthropogenic methane emissions, and hence to the greenhouse effect. 95% of this gas (wind) is emitted through burping. This has led scientists at the Commonwealth Scientific and Industrial Research Organisation of Perth, Australia, to develop an anti-methanogen vaccine to minimize methane in cow burps.One reason why cows burp so much is that they are often fed foods that their digestive systems cannot fully process, such as corn and soy.
